UN Still Sees No Sign of Biological Weapons in Ukraine
The United Nations is not aware of any biological weapons programs in Ukraine, a senior official in the Office for Disarmament Affairs (UNODA) reiterated on Thursday in a briefing to the Security Council. This marked the third time since the 24 February invasion of Ukraine that the Council has formally met at Russia’s request to address its ongoing allegations. US Ambassador Linda Thomas-Greenfield characterized the meeting as “a colossal waste of time”, saying it was held for the sole purpose of spreading disinformation. UN News

OSTP is seeking feedback from stakeholders on how to build this capacity. RFI deadline is 27 December 2022. White House
ASM Responds to Senate HELP Report on COVID Origins
“On Oct. 27, the Senate Health, Education, Labor and Pensions (HELP) Committee Minority oversight staff released an interim report titled, “An Analysis of the Origins of the COVID-19 Pandemic.” ASM appreciates the efforts of Senate staff to provide a preliminary overview of existing information related to the origin of SARS-CoV-2, but ASM respectfully disagrees with the report’s conclusion. At this time, ASM does not believe there is enough available evidence about the origins of SARS-CoV-2 to support the report’s overarching conclusion.” American Society for Microbiology

To Fix America’s Biodefense Strategy, Think Smaller
There is no doubt that the Biden administration wants to improve the nation’s pandemic preparedness, and a strategy limited to that topic would be much more appropriate, given the significant size and complexity of US health care. There are at least three major obstacles to this effort: poorly defined terms of reference, the lack of context of how these biological threats are addressed, and the challenges inherent to an interagency response to complex issues. None of these are new challenges. Breaking Defense

MEDICAL COUNTERMEASURES
Advancing Development of Medical Countermeasures: Incorporating COVID-19 Lessons Learned Into Future Pandemic Preparedness Planning
Having in place flexible MCM development and support contracts that can rapidly pivot to and evolve with new viral or bacterial pathogens are required. Improved platform technologies that can be used to develop MCMs faster and with better breadth and duration of protection against new emerging infectious diseases are needed. Working with FDA and industry to design pivotal clinical trials with sufficient power and robust endpoints is critical for expediting regulatory approval. Easy-to-use diagnostics that can be utilized in homes and other non-traditional testing settings greatly improve access to testing and have potential to reduce disease spread.

Immune Modulatory Vaccines: Time to Move Into Infectious Diseases
Immune modulatory vaccines represent a new treatment modality that is currently under intense investigation in patients with cancer. Immune modulatory vaccines are a method of stimulating the body’s endogenous anti-regulatory T cells to target immune-suppressive regulatory cells. Immune modulatory vaccines seem to represent a novel way of activating proinflammatory cells that can affect immune inhibitory pathways without inducing increased toxicity. Several antigens for immune modulatory vaccines exist, and each could be utilized alone or together depending on the type and stage of the infectious disease. Thus, further research into the natural role and effect of anti-regulatory T cells in different infectious settings, in addition to the effects of immune modulatory vaccines as monotherapy and in combination with other therapies, is highly warranted.

Development of Functional Anti-Gn Nanobodies Specific for SFTSV
Severe fever with thrombocytopenia syndrome (SFTS) is an acute infectious disease caused by novel bunyavirus (SFTSV), with a mortality rate of 6.3% ~ 30%. To date, there is no specific treatment for SFTS. Previously, researchers demonstrated that SFTSV surface glycoprotein (Glycoprotein N, Gn) was a potential target for the development of SFTS vaccine or therapeutic antibodies, and anti-Gn neutralizing antibodies played a protective role in SFTS infection. This study screens, selects and validates a nanobody highly specific for Gn. The high-throughput technical route developed in this study could also be expanded to the production of nanobodies specific for other viruses like SARS-CoV-2. Protein Science
Rift Valley Fever Vaccine Development Strategies
Rift Valley fever (RVF) is a mosquito-borne viral zoonosis that causes high fetal and neonatal mortality in ruminants and a mild to fatal hemorrhagic fever in humans. There are no licensed RVF vaccines for human use while for livestock, commercially available vaccines are all either live attenuated or inactivated and have undesirable characteristics. Novel DIVA-compatible RVF vaccines with better safety and efficacy than the licensed ones are being developed, aided fundamentally by a better understanding of the molecular biology of the RVF virus and advancements in recombinant DNA technology.

Antiviral Activity and Mechanism of Antifungal Drug, Anidulafungin, Suggesting Potential for Treatment of Viral Diseases
The severe fever with thrombocytopenia syndrome disease (SFTS), caused by the novel tick-borne SFTS virus (SFTSV), was listed among the top 10 priority infectious disease by WHO due to the high fatality rate of 5–30% and the lack of effective antiviral drugs and vaccines and therefore raised the urgent need to develop effective anti-SFTSV drugs to improve disease treatment. Anidulafungin, an antifungal drug of the echinocandin family, demonstrated a strong inhibitory effect on SFTSV entry and exerts an antiviral effect in inhibiting the entry of other viruses including SARS-CoV-2, SFTSV-related Guertu virus and Heartland virus, Crimean-Congo hemorrhagic fever virus, Zika virus, and Herpes simplex virus.

Preparing Health-Care Systems for Future Pandemics
Hospital emergency departments are “sentinel systems” for infectious disease, because they’re often the first places people go to when experiencing unusual symptoms. At present, the diagnostics available in any given hospital usually reflect the illnesses they most commonly encounter. As a result, health-care workers often do not have easy access to tests that would allow them to confirm an unusual illness for their region, as might be the case in the early days of a pandemic. To rectify this, hospitals should establish relationships with laboratories that can test for diseases that aren’t in their own wheelhouse, so that these labs can be called on quickly when needed.

Craig Spencer: We May Have Only a Few Months to Prevent the Next Pandemic
At the outset of every outbreak, a small window exists when response means the difference between containment and catastrophe. As the crisis wanes, a similar window exists when there’s enough will among people and politicians to push for better preparation for other pandemics. With Covid, that window is fast closing. While Covid causes over 300 deaths a day in the United States, a largely preventable toll that could amount to double our worst flu season, Congress remains unable to secure funding for future Covid vaccines and response, let alone the $88 billion requested over five years for pandemic preparedness and biodefense.

Serological Evidence of SFTS Virus and IgM Positivity in Healthy Residents in Vietnam
Severe fever with thrombocytopenia syndrome (SFTS), an emerging tick-borne viral disease with a high mortality rate, is prevalent in East Asia and has also been reported in Southeast Asia since 2019. SFTS patients in Vietnam were first reported in 2019. To investigate the seroprevalence of SFTSV in Vietnam, researchers collected serum samples from 714 healthy residents in Thua Thien Hue and Quang Nam Province, Vietnam. The seroprevalence ranges in Southeast Asia from 0.23% to 9.17% in China, from 1.9% to 7.7% in South Korea and from 0.14% to 0.3% in Japan, and prevalence rate is 2.5% in Pakistan. The seroprevalence rate in Vietnam is similar to that in Pakistan. Viruses

Rapid Detection of Whole Active Ricin Using a Surface-Enhanced Raman Scattering Based Sandwich Immunoassay
This study reports a reliable surface-enhanced Raman scattering (SERS)-based sandwich immunoassay for the detection and differentiation of active ricin from other homologous toxins. In the immunoassay design, magnetic bead conjugated with a monoclonal antibody (mAb) MIL50 which can recognize the ricin in its holotoxin form was used as a capture probe to separate ricin from complex matrix, while both Raman reporter molecule Nile blue A (NBA) and ricin-specific mAb 14C12 were modified on gold nanoparticles (AuNPs) to form SERS-nanoprobes. In the presence of ricin, SERS-nanoprobes bound to the antigen-captured magnetic beads and formed a sandwich immunocomplex to produce specific hot spots and then generated highly sensitive signals. As a result, the whole ricin could be detected as low as 1 ng/mL and 5 ng/mL in PBS and in plasma, respectively. Journal of Raman Spectroscopy

The Potential of Genomics for Infectious Disease Forecasting
Models used for infectious disease forecasting often cannot incorporate pathogen diversity and cannot typically be compared with genomic data. These models include the susceptible–infectious–recovered compartmental model and its myriad extensions (for example, latent periods, age structure and vaccination status). Although recent work links birth–death and coalescent phylogenetic models to compartmental models and projections, many modelling frameworks used for forecasting disease do not yet lend themselves to modelling diverse pathogens.

Genomic Characterization of Multidrug-Resistance in Two Intensive Care Units in Hanoi, Viet Nam
Here we present a large prospective genomic surveillance study of ESBL-producing or carbapenemase-producing organisms from three key AMR pathogens from two hospital ICUs in Viet Nam. Despite limiting our study samples to ESBL-producing or carbapenem-resistant isolates belonging to three species, we identified many isolates (an average of 17 isolates per day from patients in one ICU and ten per day in the other). Similar settings in England, UK, have found a small incidence of ESBL-producing or carbapenemase-producing Enterobacterales. However, across Europe and the USA, the spread of endemic ESBL-producing and carbapenemase-producing Enterobacterales has increased, particularly E. coli and K. pneumoniae, with extensive spread of high-risk lineages, such as K pneumoniae ST258 and ST512 in the USA, Israel, Italy, and Greece.

EPA Request for Comments: Clean Air in Buildings Challenge
Building upon the Biden Administration’s Clean Air in Buildings Challenge, a key component of the President’s National COVID-19 Preparedness Plan, the Environmental Protection Agency (EPA) is seeking public comment to inform efforts by EPA and others to support the widespread adoption of actions that lead to improvements in indoor air quality in the nation’s building stock, with a particular emphasis on schools and commercial buildings, to help reduce disease transmission indoors and improve public health. Comments are due by December 5, 2022. EPA
New Cohort Opportunity for Technical Assistance: Infection Prevention and Control Assessment Training (IPC-AT)
NACCHO, with support from the CDC, is accepting applications for a new cohort for local health departments (LHDs) to build infection prevention and control (IPC) capacity through partnership with APIC Consulting, a subsidiary of the Association for Professionals in Infection Control and Epidemiology (APIC). The goal of the Infection Prevention and Control Assessment Training (IPC-AT) project is to enhance IPC capacity in LHDs so they can better respond to infection threats, such as COVID-19 and healthcare-associated infections (HAIs), in long-term care facilities (LTCFs). Specifically, LHDs will receive technical assistance from a locally based board-certified Infection Preventionist who will help LHDs refine their IPC skills by conducting standardized IPC assessments and follow up. The deadline for submitting applications for technical assistance is Friday, December 2, 2022. NACCHO

European, US Officials Track BQ.1 Omicron Subvariant Rises
In an epidemiologic update, the ECDC said initial studies by Asian researchers suggest that BQ.1 has the ability to evade earlier immunity from illness and vaccines, but so far, there is no evidence that infections involving the subvariant are more severe. In the US, BQ.1 and BQ.1.1 are spreading relatively quickly, but still make up a small proportion of the overall variant picture. CDC also said it is keeping a close eye on XBB based on international reports, though it is still very rare in the United States. CIDRAP
Covid, Flu, RSV: Hospitalizations Rise as Wave of Viruses Hits New York
New Yorkers are falling ill with new variants of Covid and old illnesses like flu and RSV that masking and other precautions once held at bay. The Omicron variant that accounted for most infections through the summer, BA.5, is now giving way to a variant soup — a mixture of different Omicron subvariants, including BQ.1 and BQ.1.1, which are even more transmissible and better at dodging immunity. With most testing now done at home, it is hard to get a clear picture of the amount of virus circulating. The city’s official Covid case numbers have been holding steady for two months, at about 2,000 cases reported per day. But hospitalizations have again started to increase. New York Times
U.S. Searches for Backup for Key Covid Therapy for Immunocompromised People
Health officials are bracing for the prospect that the country’s sole preventive Covid-19 treatment for immunocompromised people could be ineffective this winter. AstraZeneca’s Evusheld, the only monoclonal antibody authorized as a periodic injection to prevent infection, has become an essential shot for roughly Americans with weakened immune systems. But news this month that it is not effective against a steadily climbing coronavirus strain sent health officials racing to game out other antibody options and convene a meeting with patient groups. The situation reflects larger questions about the Biden administration’s ability to respond to evolving Covid-19 variants with a shrinking coronavirus response budget (and seeming unwillingness to promote appropriate NPIs in high-risk settings) STAT
COVID ‘Variant Soup’ is Making Winter Surges Hard to Predict
In Europe, North America and Africa, the prevalence of Omicron offshoots in the BQ.1 family is rising quickly, even as overall cases seem to fall. In Asian countries including Singapore, Bangladesh and India, a lineage called XBB has already set off fresh waves of infection. Scientists are closely watching several regions where both are circulating, to see which has the edge. Nature
ACT-Accelerator Launches Six Month Plan as World Transitions to Long-Term COVID-19 Control
The Access to COVID-19 Tools (ACT) Accelerator this week launched its plan for the next six months, setting out how, as a partnership of global health agencies working alongside government, civil society and other partners, it will support countries as the world transitions to long-term COVID-19 control. Priority areas include: focusing research and development (R&D) and market shaping activities to ensure a pipeline for new and enhanced COVID-19 tools; securing institutional arrangements for sustained access for all countries to COVID-19 vaccines, tests and treatments, including oxygen; and concentrating in-country work on new product introduction (e.g., new oral antivirals for those at highest risk) and protection of priority populations (e.g., full vaccination of health care workers and older populations), in support of national and international targets.

EBOLA OUTBREAK – UGANDA
Ebola Update 28 October
As of 26 October, a total of 115 confirmed and 21 probable cases, including 32 confirmed and 21 probable deaths have been reported. Overall, 15 cases with four deaths have been reported among healthcare workers. 1844 contacts were under surveillance in nine districts of the country. A cumulative total of 3166 contacts have been listed since the start of this outbreak, of which 1194 (37.7%) have completed the follow-up period of 21 days. A total of 94 safe and dignified burials (SDB) have been undertaken since the beginning of the outbreak, of which 97.9% (n=92) were community burials. World Health Organization
Merck Locates Frozen Batch of Undisclosed Ebola Vaccine, Will Donate for Testing in Uganda’s Outbreak
In a revelation that may help Uganda combat its outbreak of Ebola, the pharmaceutical giant Merck has acknowledged that it has up to 100,000 doses of an experimental vaccine for the deadly viral disease in its freezers in Pennsylvania and will donate them. The Merck vaccine targets Sudan ebolavirus, the pathogen now circulating in Uganda. Merck quietly made the product in 2015 and 2016, soon after it had a landmark success with a similar vaccine against Zaire ebolavirus, a different virus that caused a big epidemic in West Africa between 2014 and 2016. The company froze the Sudan Ebola vaccine in bulk form and never tested it on people. But it has been shown to protect monkeys intentionally infected with Sudan ebolavirus, and given the efficacy of Merck’s Zaire Ebola vaccine, scientists have high hopes that the Sudan Ebola shots will be safe and effective as well. Science
Uganda Green-Lights Ebola Vaccine Trials
Uganda’s health minister announced yesterday that officials will evaluate three Sudan Ebola vaccine candidates in the coming weeks, and she revealed that healthcare workers are already testing some new treatment options (including monoclonal antibodies, as well as repurposed drugs such as Remdesivir, a broad-spectrum antiviral, that was donated by the US government). The three Sudan Ebola vaccines are from Oxford University in the United Kingdom and Sabin Vaccine Institute and Merck in the United States. CIDRAP
Red Cross and Community Members Fight Ebola’s Spread in Uganda
The IFRC urgently seeks CHF 10 million to address gaps and procure Personal Protective Equipment (PPE) for Uganda Red Cross staff and volunteers, who are at the forefront of the Ebola response. IFRC’s appeal will help address these and other needs, such as building the frontline team’s capacity to manage safe and dignified burials. The Uganda Red Cross has more than 500,000 volunteers and members spread across 51 branches and over 300 staff members including a skilled health department with health experts in areas directly linked to the epidemic response.

Many U.S. Labs Cannot Test for Ebola Strain Behind Uganda’s Swelling Outbreak
The federal push to scale up U.S. testing capacity for Sudan Ebolavirus comes as authorities have been bracing for the “low” risk that an infected traveler could bring it into the country from Uganda. A few weeks ago, only eight members of the Laboratory Response Network (LRN) had the ability to test. That number has now risen to 22 labs across the network, a CDC spokesperson said Tuesday. Unlike Zaire Ebolavirus, there are no rapid test kits available to spot infections by Sudan Ebolavirus. On Monday, the Biden administration announced it had awarded an additional $21 million to the hospitals and was adding a handful of new facilities to the nation’s “National Special Pathogen System.” CBS News
CHOLERA CRISIS
Cholera Outbreaks Threaten Children’s Survival in the Middle East
As Syria’s first major outbreak of cholera in over a decade spreads, thousands of children in neighbouring countries are also at risk from the deadly disease, with Lebanon’s recorded cases nearly doubling since last week. The acute epidemic in Syria has left over 20,000 suspected cases with acute watery diarrhoea and 75 cholera-associated deaths since its start [1]. In Lebanon, confirmed cholera cases reached 448 in just two weeks, with 10 associated deaths. Unicef
Cholera Overwhelms Haiti as Cases, Deaths Spike Amid Crisis
Since the notification of the first two confirmed cases of cholera in the greater Port-au-Prince area on 2 October 2022, health officials have reported a total of 2,243 suspected cases, including 219 confirmed cases, 1,415 hospitalized suspected cases, and 55 registered deaths. Worsening the situation is a lack of fuel and water that began to dwindle last month when one of Haiti’s most powerful gangs surrounded a key fuel terminal and demanded the resignation of Prime Minister Ariel Henry. Gas stations and businesses including water companies have closed, forcing an increasing number of people to rely on untreated water. AP News, PAHO

Four Countries Report New Polio Cases
Four countries have new polio cases this week, all vaccine-derived types. Benin, the Democratic Republic of the Congo (DRC), and Yemen have more circulating vaccine-derived poliovirus type 2 (cVDPV2) cases, while the DRC and Malawi have circulating type 1 (cVDPV1) cases, according to the weekly report published by the Global Polio Eradication Initiative (GPEI).

Wastewater Testing and Detection of Poliovirus Type 2 Genetically Linked to Virus Isolated from a Paralytic Polio Case — New York
Wastewater testing has identified circulating polioviruses genetically related to virus isolated from the Rockland County patient in at least five New York counties. Public health efforts to prevent polio should focus on improving coverage with inactivated polio vaccine. Although most persons in the United States are sufficiently immunized, unvaccinated or undervaccinated persons living or working in Kings, Orange, Queens, Rockland, or Sullivan counties, New York should complete the polio vaccination series to prevent additional paralytic cases and curtail transmission.

CDC Considers Reintroducing Oral Form of Vaccine for Polio Outbreak in New York
A novel form of the oral, live virus polio vaccine is being considered by the CDC for an outbreak and ongoing detection of the virus in New York, following a presentation by the Polio Vaccine Work Group at the October meeting of the CDC’s Advisory Committee on Immunization Practices (ACIP). The decision to employ the oral vaccine will not be made without further deliberation. “It will be a process. It’s not something that we can pull the trigger on and have it appear overnight. There will be lots of thought and discussion about the reintroduction of an oral polio vaccine into the United States.” Contagion Live
HANTAVIRUS
Confirmed Hantavirus in Neuquén: 6 Close Contacts in Quarantine for 45 Days
The Ministry of Health of the Province of Neuquén, Argentina confirmed a hantavirus case on 26 Oct. The patient is a 28-year-old person from the town of San Martín de los Andes, who remains isolated and hospitalized in intensive care at the local hospital. Six people (including cohabiting and non-cohabiting relatives) must remain quarantined for 45 days in their personal homes and under a strict monitoring program with the aim of avoiding potential infections and detecting new onset illness early. Hantavirus is spread by inhaling contaminated air in open or closed places, where infected rodents eliminate it through saliva, feces and urine. As they dry, they combine with dust and become airborne. In addition, it can be spread by bites or direct contact by touching these living or dead animals that transmit the germ. Diario Hoy
Characterization of the Human Neutralizing Antibody Response to New World Hantavirus Infection
Hantaviruses are high-priority emerging pathogens carried by rodents and transmitted to humans by aerosolized excreta or, in rare cases, person-to-person contact. While sporadic in North and South America, many infections occur in Europe and Asia, with mortality ranging from 1 to 40% depending on the hantavirus species. There are currently no FDA-approved vaccines or therapeutics for hantaviruses. This work describes human monoclonal antibodies isolated from individuals previously infected with Sin Nombre virus or Andes virus. Most SNV-reactive antibodies show broad recognition and cross-clade neutralizing activity, while many ANDV-reactive antibodies show activity for ANDV only. Four mAbs show therapeutic efficacy at clinically relevant doses in hamsters. Vanderbilt University
Evidence for Human-to-Human Transmission of Hantavirus: A Systematic Review
Hantavirus is known to be transmitted from rodents to humans. However, some reports from Argentina and Chile have claimed that the hantavirus strain Andes virus (ANDV) can cause human-to-human transmission of the disease. Based on this review, the balance of the evidence does not support the claim of human-to-human transmission of ANDV. Well-designed cohort and case-control studies that control for co-exposure to rodents are needed to inform public health recommendations. Universidad de Sonora
RSV – RESPIRATORY SYNCTIAL VIRUS
Hospitals Overwhelmed by Pediatric Patients with Respiratory Virus

Flu/RSV Coinfection Produces Hybrid Virus that Evades Immune Defenses
When fused to RSV, influenza A virus is better able to escape antibodies that usually neutralize it, an in vitro study finds. To understand the effects of coinfection in vitro, the team infected human lung cells with IAV and RSV simultaneously. Treating the cells with antibodies against influenza A did not block the spread of infection, the researchers found. The hybrid simply used its RSV proteins to infect cells instead. “Influenza is using hybrid viral particles as a Trojan horse.” The Scientist

While RSV Surges, Shortage of Pediatric Hospital Beds Delays Care for Some Kids
Pediatric hospital beds are more full now than they have been in the past two years. This crush of young patients filling hospitals now means those with less urgent illnesses may face long waits and sometimes days-long stays in the ER while they wait to be admitted. It also means kids who need cancer treatment or surgery may be sent home to wait until hospitals have beds. CNN
MONKEYPOX
Clinicians at Low Risk of Acquiring Monkeypox from Patients
An investigation by Colorado public health authorities found no monkeypox cases among 313 health care workers exposed to 55 patients with the virus, despite low adherence to preventive measures among the workers. The report adds to evidence that the overall risk to health care workers appears low. At least one US health care worker had a work-related monkeypox infection during the current outbreak and a health care worker in the UK became infected after handling patient linens during a 2018 outbreak. JAMA
Severe Monkeypox in Hospitalized Patients — United States
During August–October 2022, CDC provided clinical consultation for 57 hospitalized patients with severe manifestations of monkeypox, most of whom were Black men with AIDS. Delays were observed in initiation of monkeypox-directed therapies. Twelve patients died, and monkeypox was a cause of death or contributing factor in five patients to date, with several other deaths still under investigation. MMWR
Monkeypox Review
By October 7, 2022, a total of 71,096 cases of monkeypox infection had been reported in 107 locations worldwide, with 70,377 of the cases in countries that have not historically reported monkeypox.53 The largest numbers of cases have been reported in the United States, followed by Brazil and Spain. An analysis of 24,677 cases of monkeypox performed by the ECDC and the WHO, as of October 4, 2022, showed disproportionate numbers of cases in men (98.5%). Sexual orientation was known for 10,729 of the male patients, of whom 10,300 (96.0%) identified themselves as MSM. New England Journal of Medicine
Demographics of Patients Receiving TPOXX for Treatment of Monkeypox
As of 26 October, the cumulative number of patients prescribed or treated with TPOXX reported to the CDC is 4,822. This number likely underestimates the number of patients who are receiving TPOXX treatment as healthcare providers can start treatment before submitting IND paperwork to CDC. CDC
Lack of Clinical Evidence of Antiviral Therapy for Human Monkeypox
Few studies reported on antiviral treatment usage and subsequent clinical courses. To date, one systematic review based on literature up until 2018 has been completed on the potential efficacy of tecovirimat, brincidofovir, and cidofovir against orthopoxvirus infections, including the monkeypox virus [5]. To update and respond to this multi-country monkeypox outbreak in non-endemic countries, our systematic review aimed to evaluate and summarize the existing research on the efficacy and safety of tecovirimat, brincidofovir, and cidofovir for patients with monkeypox.

The Need for Better Diagnostics to Support Diagnosis and Surveillance in Monkeypox Endemic Countries
Even though case numbers are now subsiding in non-endemic countries, as of Sept 11, the WHO Regional Office for Africa reported a 12.6% increase in case numbers within 1 week (from 524 in week 35, to 590 in week 36). Notably, the WHO Regional Office for Africa epidemiological update from May 2022, before monkeypox started spreading in non-endemic countries, stated that in the Democratic Republic of the Congo, between epidemiological week 1 and week 15 of 2022, 1152 cases associated with 55 deaths had been reported (amounting to an estimated case fatality rate of 4.8%). The high number of reported deaths is not only due to the different circulating clades of the monkeypox virus (the West African clade responsible for the current outbreak is associated with milder disease), but is also probably due to surveillance artifacts considering that reports of cases and deaths are typically based on symptoms and epidemiological correlations rather than confirmation of infection using molecular or other laboratory diagnoses.

WEST NILE VIRUS
Colorado Sees Worst Year for West Nile Virus Since 2003
Most people who get West Nile virus never know they were infected, and those who do get sick typically have flu-like symptoms. In a small percentage of cases, though, the virus invades the brain or spinal cord, potentially causing disability or death. As of Friday, the state had recorded 195 total cases, which is almost certainly a significant undercount since most people wouldn’t know to get tested. Hospitalizations were at their third-highest level since the state started counting in 2003, with 135 people receiving care for severe symptoms. Denver Post
West Nile Virus Cases Could Set a North Carolina Record in 2022
State health officials have recorded 10 cases of West Nile Virus and 2 fatalities so far this year, with several weeks of warm weather left likely to mean more infections could be percolating. Positive cases have been reported in − among others − New Hanover, Cumberland, Wake, Mecklenburg, and Catawba counties, with both fatalities in Cumberland County. The first death of a North Carolinian from West Nile virus this year was confirmed Oct 4, days after Hurricane Ian dumped several inches of rain on most of North Carolina. Star News Online

AVIAN INFLUENZA
Avian Flu is Spiking, Taking Out Millions of Holiday Turkeys
The rampant spread of the virus has already eliminated more than 6 million turkeys nationwide, and leaving farmers short of their usual offerings. The virus largely originates with wild birds, which can infect all kinds of poultry via their droppings when they fly over farms. But turkeys seem uniquely vulnerable. While wild birds may carry it without becoming sick, infected domesticated chickens and turkeys may exhibit tremors, trouble breathing and extreme diarrhea followed by a swift death. The USDA has scrambled to educate poultry businesses about best practices and how to identify signs of illness, which experts say has a 90 to 100 percent mortality rate in turkeys and chickens within 48 hours. The virus kills so quickly that multiple dead or dying birds can be the first sign a flock is infected. Washington Post
Japan Reports First Bird Flu Outbreaks of Season, Culling 340,000 Chickens
Japan has detected its first outbreaks of bird flu for the season in 2022, with a “highly pathogenic” strain identified at a poultry farm on the main island of Honshu, while the other outbreak was found on the northern island of Hokkaido. About 170,000 egg-laying chickens are being exterminated at a farm in Kurashiki city, Okayama Prefecture, the agriculture ministry said on its website on Friday. It also established restricted zones up to 10 km (6.2 miles) from the site. Around 170,000 egg-laying chickens are also being culled at the farm in Atsuma town in Hokkaido, the ministry said. Reuters
Levels of Influenza A Virus Defective Viral Genomes Determine Pathogenesis in the BALB/c Mouse Model
Mammalian infections with highly pathogenic avian influenza viruses (HPAIVs) cause severe disease associated with excessive proinflammatory cytokine production. Aberrant replication products, such as defective viral genomes (DVGs), can stimulate the antiviral response, and cytokine induction is associated with their emergence in vivo. Here researchers show that stocks of a recombinant virus containing HPAIV internal genes that differ in their amounts of DVGs have vastly diverse outcomes in a mouse model. This study also emphasizes the crucial requirement to examine the quality of virus preparations regarding DVG content to ensure reproducible research. Journal of Virology
Airborne Avian Influenza Virus in Ambient Air in the Winter Habitats of Migratory Birds
This study aimed to evaluate airborne AIV, specifically H5, H7, and H9, in a critical winter habitat of migratory birds and assess the factors influencing airborne AIV transmission in ambient air to provide novel insights into the epidemiology of avian influenza. The daily mean temperature and daily maximum temperature had a significant negative correlation with influenza A, H7, and H9. Cold air masses and bird migration were significantly associated with airborne H9 and H7, respectively. In addition, we observed a significant correlation between AIV and the number of pintails, common teals, Indian spot-billed ducks, northern shovelers, Eurasian wigeons, tufted ducks, pied avocets, black-faced spoonbills, and great cormorants.

UK: New Package of Measures Announced to Support Poultry Industry with Bird Flu
New government support for the poultry industry has been announced today to assist farmers and producers with the impacts of bird flu. The UK is dealing with its worst ever bird flu outbreak with over 200 cases confirmed across the country in the last 12 months. Under the new plans, the Government will alter the existing bird flu compensation scheme allowing compensation to be paid to farmers from the outset of planned culling rather than at the end. The Food Standards Agency, an easement to marketing rules is also being introduced in England. The measures mean that farmers who breed turkeys, geese or ducks for their meat will have the option to slaughter their flocks early and to freeze these products, which can then be defrosted and sold to consumers between the period 28 November and 31 December 2022. This option will give farmers certainty over business planning. GOV.UK

India: African Swine Fever Reported in Kerala
Authorities in parts of Kerala shut down meat shops selling pork after African Swine Flu cases were confirmed at a pig farm in the Kottayam district. Steps have been taken to ensure that no pigs are transported from the infected zone. 949 pigs have been culled so far. Livestock experts said they could not rule out chances of the infection spreading to more parts of the state, citing the situation in north-eastern Indian states — which are reeling under the threat of ASF which claimed the lives of almost 80% of domestic pigs.

Withdrawal of Select Agent Regulatory Exclusions for Two Strains of African Swine Fever Virus
The Animal and Plant Health Inspection Service (APHIS) has withdrawn the select agent regulatory exclusions for two African swine fever virus strains. APHIS withdrew the select agent regulatory exclusions for these strains because it has evaluated new information and determined that they have the potential to pose a severe threat to animal health or animal products. Possession, use, and transfer of the designated ASFV strains must now comply with the select agent and toxin regulations under the authority of the Agricultural Bioterrorism Protection Act of 2002.

Draft Genome Sequence Analysis of the Genotype II African Swine Fever Virus from India
African Swine Fever (ASF) is an alarming threat to the pig population across the world. ASF virus entered the northeastern NE part of India early in 2020, causing huge economic loss to the pig sector. Here, researchers present a brief report on the draft genome sequence of an ASFV strain from Assam state of NE India belonging to genotype II. This will strengthen the baseline data needed for epidemiological investigations and for the generation and design of diagnostics and vaccines. Microbiology Resource Announcements
Review of the Pig-Adapted African Swine Fever Viruses in and Outside Africa
Whilst ASF vaccines are critical for high-production systems, global food security relies on parallel efforts to improve biosecurity and pig production and on continued ASFV surveillance and characterization. Most of the experimental ASF vaccines described do not protect against a wider spectrum of viruses and may be less useful in the event of incursions of different strains or where multiple genotypes co-exist.

European Study Into ASF Virus Survival in Feed, Materials
African swine fever viruses that may have been introduced into processed byproducts, grain, oilseed meals and compound feed are largely inactivated as a result of the processing steps involved in feed manufacture. This is a key finding of a study of published literature by Germany’s Friedrich Loeffler Institute and Federal Institute for Risk Assessment, as well as the National Veterinary Institute of Sweden (SVA). However, both of the studies highlight a level of uncertainty in their conclusions arising from a lack of scientific data in some areas. A new German-Swedish collaboration aims to fill in those gaps by investigating the stability of ASF viruses in a range of animal feeds and bedding materials under conditions of processing and storage.
