Abstract
Currently, no immunomodulatory agents have been conclusively shown to benefit severe influenza. The World Health Organization conditionally advises against the use of systemic corticosteroids, macrolides, plasma therapy, mechanistic target of rapamycin inhibitors, and nonsteroidal anti-inflammatory drugs for such patients. High-dose systemic corticosteroids may increase mortality and morbidity in severe influenza; the potential of low-dose corticosteroids merits further study given survival benefits in patients with severe coronavirus disease 2019 (COVID-19). Passive immunotherapy using convalescent plasma or intravenous immunoglobulin (IVIG) from healthy donors has not proven effective, suggesting that future research should focus on hyperimmune plasma or IVIG from recent infections. An open-label randomized controlled trial (RCT) found that a triple combination of oseltamivir, clarithromycin, and naproxen improved outcomes in severe influenza. One RCT has indicated that sirolimus with corticosteroids can expedite liberation from mechanical ventilation and reduce viral load, warranting larger trials of sirolimus alone. In contrast, adding macrolides or nitazoxanide has not consistently improved clinical outcomes. Promising evidence exists for anti-C5a antibodies in COVID-19, while case reports hint that intravenous N-acetylcysteine may benefit severe influenza pneumonia. Observational data on statins remain conflicting. Further studies on COX-2 inhibitors in combination with antivirals and other immunomodulators are needed. Mycophenolic acid, pamidronate, and peroxisome proliferator-activated receptor gamma agonists are low priorities due to toxicity concerns. Research into human mesenchymal stromal cells and herbal medicine remains inconclusive. Overall, these findings support large-scale trials to validate promising results and address limitations in small studies. Treatment of severe influenza requires a multidisciplinary approach that integrates antiviral and immunomodulatory strategies. Clarifying these roles may enhance patient outcomes.

Abstract
The Goose/Guandong lineage of highly pathogenic avian influenza virus [A/Goose/Guangdong/1/1996(H5N1)] is the progenitor of the currently circulating Eurasian-lineage highly pathogenic avian influenza H5N1 clade 2.3.4.4b and has been the most consequential highly pathogenic avian influenza lineage globally. Despite increased reports of infections, the extent of exposure and role of wild mammals in the ecology and transmission dynamics of the virus remains poorly understood. We surveyed wild mammals in Ohio, United States to investigate the potential spillover of highly pathogenic H5N1 avian influenza clade 2.3.4.4b. While no active infections—defined as positive results indicative of viral replication and potential propagation—were detected by swab-based molecular tests, serological assays revealed antibodies against multiple avian influenza virus antigens in raccoons and opossums. Specifically, antibodies to avian influenza virus nucleoprotein were detected in 54.9% (n = 61) of samples using enzyme-linked immunosorbent assay; antibodies to Eurasian-lineage highly pathogenic avian influenza H5 clade 2.3.4.4b and North American low pathogenic avian influenza H5 were detected in 43.2% (n = 48) and 22.5% (n = 25) of samples, respectively, using virus neutralization assays; and antibodies to avian influenza virus neuraminidase were detected in 44.1% (n = 49) of samples using enzyme-linked lectin assay. All seropositive animals were sampled at Ohio marshes with previously confirmed highly pathogenic avian influenza H5N1 detections in waterfowl. These findings suggest prior exposure of wild mammals to these viruses without mortality events. Wild mammals may play an intermediary role in the mammalian adaptation of avian influenza A viruses. Therefore, ongoing surveillance of wild mammals is crucial for assessing the risk to public health.

Highlights
-- We conducted surveillance for influenza A viruses at live bird markets in northern Vietnam.
-- Six different subtypes of influenza A virus were found co-circulating in the markets.
-- Notable genetic mutations were found across many genes.
-- These markets have great potential to generate new pandemic influenza A virus strains.
Abstract
Objectives
Live bird markets (LBMs) in Asia have often been the source of human infections with avian influenza virus (AIV).
Methods
From July 2021 to August 2023, we employed a One Health approach in conducting periodic surveillance for novel influenza A viruses in five LBMs in northern Vietnam. Specimens were studied with egg culture, molecular assays, Sanger sequencing, and next-generation sequencing.
Results
We studied a total of 688 human, avian, and bioaerosol specimens. Among these, 118 (17.2%) were found to have molecular evidence of AIVs. Next-generation sequencing of 92 isolates revealed multiple AIV subtypes, including H4N6 (n=1), H5N1 (n=3), H5N8 (n=6), H6N2 (n=3), H6N6 (n=18), and H9N2 (n=61) and mix infections (n=7). Our H5Nx sequences belonged to the Eurasian lineage clade 2.3.4.4b, while our H6N2 sequences were of group III, H6N6 of group II, and H9N2 of the BJ94-lineage clade 4.6.14.
Conclusions
The relatively high prevalence of AIV, particularly highly pathogenic H5N1 and H5N8 viruses, along with the subtype diversity, frequent co-infections and notable mutations, highlights the urgent need for continued monitoring and control of AIV in Vietnam’s poultry farms and LBMs.

Summary
Background
For more than three decades, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has provided a framework to quantify health loss due to diseases, injuries, and associated risk factors. This paper presents GBD 2023 findings on disease and injury burden and risk-attributable health loss, offering a global audit of the state of world health to inform public health priorities. This work captures the evolving landscape of health metrics across age groups, sexes, and locations, while reflecting on the remaining post-COVID-19 challenges to achieving our collective global health ambitions.
Methods
The GBD 2023 combined analysis estimated years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs) for 375 diseases and injuries, and risk-attributable burden associated with 88 modifiable risk factors. Of the more than 310 000 total data sources used for all GBD 2023 (about 30% of which were new to this estimation round), more than 120 000 sources were used for estimation of disease and injury burden and 59 000 for risk factor estimation, and included vital registration systems, surveys, disease registries, and published scientific literature. Data were analysed using previously established modelling approaches, such as disease modelling meta-regression version 2.1 (DisMod-MR 2.1) and comparative risk assessment methods. Diseases and injuries were categorised into four levels on the basis of the established GBD cause hierarchy, as were risk factors using the GBD risk hierarchy. Estimates stratified by age, sex, location, and year from 1990 to 2023 were focused on disease-specific time trends over the 2010–23 period and presented as counts (to three significant figures) and age-standardised rates per 100 000 person-years (to one decimal place). For each measure, 95% uncertainty intervals [UIs] were calculated with the 2·5th and 97·5th percentile ordered values from a 250-draw distribution.
Findings
Total numbers of global DALYs grew 6·1% (95% UI 4·0–8·1), from 2·64 billion (2·46–2·86) in 2010 to 2·80 billion (2·57–3·08) in 2023, but age-standardised DALY rates, which account for population growth and ageing, decreased by 12·6% (11·0–14·1), revealing large long-term health improvements. Non-communicable diseases (NCDs) contributed 1·45 billion (1·31–1·61) global DALYs in 2010, increasing to 1·80 billion (1·63–2·03) in 2023, alongside a concurrent 4·1% (1·9–6·3) reduction in age-standardised rates. Based on DALY counts, the leading level 3 NCDs in 2023 were ischaemic heart disease (193 million [176–209] DALYs), stroke (157 million [141–172]), and diabetes (90·2 million [75·2–107]), with the largest increases in age-standardised rates since 2010 occurring for anxiety disorders (62·8% [34·0–107·5]), depressive disorders (26·3% [11·6–42·9]), and diabetes (14·9% [7·5–25·6]). Remarkable health gains were made for communicable, maternal, neonatal, and nutritional (CMNN) diseases, with DALYs falling from 874 million (837–917) in 2010 to 681 million (642–736) in 2023, and a 25·8% (22·6–28·7) reduction in age-standardised DALY rates. During the COVID-19 pandemic, DALYs due to CMNN diseases rose but returned to pre-pandemic levels by 2023. From 2010 to 2023, decreases in age-standardised rates for CMNN diseases were led by rate decreases of 49·1% (32·7–61·0) for diarrhoeal diseases, 42·9% (38·0–48·0) for HIV/AIDS, and 42·2% (23·6–56·6) for tuberculosis. Neonatal disorders and lower respiratory infections remained the leading level 3 CMNN causes globally in 2023, although both showed notable rate decreases from 2010, declining by 16·5% (10·6–22·0) and 24·8% (7·4–36·7), respectively. Injury-related age-standardised DALY rates decreased by 15·6% (10·7–19·8) over the same period. Differences in burden due to NCDs, CMNN diseases, and injuries persisted across age, sex, time, and location. Based on our risk analysis, nearly 50% (1·27 billion [1·18–1·38]) of the roughly 2·80 billion total global DALYs in 2023 were attributable to the 88 risk factors analysed in GBD. Globally, the five level 3 risk factors contributing the highest proportion of risk-attributable DALYs were high systolic blood pressure (SBP), particulate matter pollution, high fasting plasma glucose (FPG), smoking, and low birthweight and short gestation—with high SBP accounting for 8·4% (6·9–10·0) of total DALYs. Of the three overarching level 1 GBD risk factor categories—behavioural, metabolic, and environmental and occupational—risk-attributable DALYs rose between 2010 and 2023 only for metabolic risks, increasing by 30·7% (24·8–37·3); however, age-standardised DALY rates attributable to metabolic risks decreased by 6·7% (2·0–11·0) over the same period. For all but three of the 25 leading level 3 risk factors, age-standardised rates dropped between 2010 and 2023—eg, declining by 54·4% (38·7–65·3) for unsafe sanitation, 50·5% (33·3–63·1) for unsafe water source, and 45·2% (25·6–72·0) for no access to handwashing facility, and by 44·9% (37·3–53·5) for child growth failure. The three leading level 3 risk factors for which age-standardised attributable DALY rates rose were high BMI (10·5% [0·1 to 20·9]), drug use (8·4% [2·6 to 15·3]), and high FPG (6·2% [–2·7 to 15·6]; non-significant).
Interpretation
Our findings underscore the complex and dynamic nature of global health challenges. Since 2010, there have been large decreases in burden due to CMNN diseases and many environmental and behavioural risk factors, juxtaposed with sizeable increases in DALYs attributable to metabolic risk factors and NCDs in growing and ageing populations. This long-observed consequence of the global epidemiological transition was only temporarily interrupted by the COVID-19 pandemic. The substantially decreasing CMNN disease burden, despite the 2008 global financial crisis and pandemic-related disruptions, is one of the greatest collective public health successes known. However, these achievements are at risk of being reversed due to major cuts to development assistance for health globally, the effects of which will hit low-income countries with high burden the hardest. Without sustained investment in evidence-based interventions and policies, progress could stall or reverse, leading to widespread human costs and geopolitical instability. Moreover, the rising NCD burden necessitates intensified efforts to mitigate exposure to leading risk factors—eg, air pollution, smoking, and metabolic risks, such as high SBP, BMI, and FPG—including policies that promote food security, healthier diets, physical activity, and equitable and expanded access to potential treatments, such as GLP-1 receptor agonists. Decisive, coordinated action is needed to address long-standing yet growing health challenges, including depressive and anxiety disorders. Yet this can be only part of the solution. Our response to the NCD syndemic—the complex interaction of multiple health risks, social determinants, and systemic challenges—will define the future landscape of global health. To ensure human wellbeing, economic stability, and social equity, global action to sustain and advance health gains must prioritise reducing disparities by addressing socioeconomic and demographic determinants, ensuring equitable health-care access, tackling malnutrition, strengthening health systems, and improving vaccination coverage. We live in times of great opportunity.

Abstract
The SARS outbreak and influenza A(H5N1) infections (2003–2004) prompted WHO to establish a global influenza antiviral stockpile, enabling rapid distribution to 72 countries during the 2009 A(H1N1) pandemic. To improve access in low- and middle-income countries, WHO added antivirals to the WHO Model List of Essential Medicines and included them in the Prequalification Programme. The 2011 Pandemic Influenza Preparedness Framework refined strategies for equitable access and rapid response. Lessons from COVID-19 led to a new WHO-led mechanism—the Interim Medical Countermeasures Network (i-MCM-net)—which supports integrated supply chains, real-time data sharing, research and development, and equitable access. WHO continues to emphasise equity and global solidarity, highlighting the need for accessible, effective, and affordable antivirals alongside vaccines to protect vulnerable populations and mitigate the impact of future pandemics.

Abstract
Influenza antivirals play an important role in the prevention and control of influenza. We reviewed data on the effectiveness of influenza antivirals for reducing influenza transmission. We found that antiviral prophylaxis, whether given pre- or postexposure, has been shown to reduce the risk of symptomatic influenza in a variety of settings and populations. During pandemic responses, antiviral prophylaxis could play an important role, as demonstrated by the use of amantadine in the 1968–1969 influenza A(H3N2) pandemic and oseltamivir during the 2009–2010 influenza A(H1N1)pdm09 pandemic. Antiviral treatment reduces symptom severity, prevents complications, and can reduce onward transmission of infection. However, resistance, accessibility, and timing pose challenges. Future research directions include innovative therapies and combination treatments. Continued research and stewardship are crucial to optimize antiviral impact.

Abstract
SARS-like betacoronaviruses (sarbecoviruses) endemic in bats pose a significant zoonotic threat to humans. Genetic pathways associated with spillover of bat sarbecoviruses into humans are incompletely understood. We previously showed that the wild-type spike of the rhinolophid bat coronavirus SHC014-CoV has poor entry activity and uncovered two distinct genetic pathways outside the receptor-binding domain (RBD) that increased spike opening, ACE2 binding, and cell entry. Herein, we show that the widely studied bat sarbecovirus WIV1-CoV is likely a cell culture-adapted variant whose progenitor bears a spike resembling that of Rs3367-CoV, which was sequenced from the same population of rhinolophid bats as SHC014-CoV. Our findings suggest that the acquisition of a single amino-acid substitution in the ‘630-loop’ of the S1 subunit was the key spike adaptation event during the successful isolation of WIV1-CoV, and that it enhances spike opening, virus-receptor recognition, and cell entry in much the same manner as the substitutions we previously identified in SHC014-CoV using a pseudotype system. The conformational constraints on both the SHC014-CoV and Rs3367-CoV spikes could be alleviated by pre-cleaving them with trypsin, suggesting that the spike-opening substitutions arose to circumvent the lack of S1–S2 cleavage. We propose that the ‘locked-down’ nature of these spikes and their requirement for S1–S2 cleavage to engage ACE2 represent viral optimizations for a fecal-oral lifestyle and immune evasion in their natural hosts. These adaptations may be a broader property of bat sarbecoviruses than currently recognized. The acquisition of a polybasic furin cleavage site at the S1–S2 boundary is accepted as a key viral adaptation for SARS-CoV-2 emergence that overcame a host protease barrier to viral entry in the mammalian respiratory tract. Our results suggest alternative spillover scenarios in which spike-opening substitutions that promote virus-receptor binding and entry could precede, or even initially replace, substitutions that enhance spike cleavage in the zoonotic host.

Abstract
Wastewater surveillance of respiratory pathogens can provide timely estimates of viral activity and disease trends in a population. Indoor air surveillance could be used similarly with some advantages but remains largely unvalidated at the community-scale. Here, an indoor air surveillance program was employed as part of public health environmental surveillance in Chicago, Illinois, USA. Ten air samplers were placed in healthcare and congregate living settings across the city. Weekly air samples were evaluated for influenza A, influenza B, respiratory syncytial virus, and SARS-CoV-2 over two respiratory virus seasons. Citywide, aggregated air sample positivity and viral load were closely correlated with local clinical case and wastewater surveillance data across all respiratory viruses. Virus trends in air data often preceded clinical and wastewater, although this varied across pathogens and respiratory virus seasons. Further, whole-genome sequencing of SARS-CoV-2 showed close correlation of variant proportions across all datasets. At the building-scale, air samples obtained from a single sampling device provided efficient respiratory virus surveillance, with well-correlated estimates of respiratory pathogens. These data demonstrate that air surveillance can provide accurate estimates of respiratory virus infections and variants at a building or community-scale, serving as an alternative or complementary tool for public health environmental surveillance.

ALBANY, N.Y. (October 14, 2025) — The New York State Department of Health today announced that a case of locally acquired chikungunya has been confirmed in New York State. Laboratory testing at the Department's Wadsworth Center confirmed the case in Nassau County on Long Island. This marks the first locally acquired case of chikungunya reported in New York State. No locally acquired cases have been reported in the U.S. states and territories since 2019.
An investigation suggests that the individual likely contracted the virus following a bite from an infected mosquito. While the case is classified as locally acquired based on current information, the precise source of exposure is not known. The Aedes albopictus mosquito, known to transmit chikungunya, is present in parts of downstate New York. Local transmission can occur when an A. albopictus mosquito bites an infected traveler, becomes infected and bites another person. The disease cannot be spread directly from one person to another.
"Our Wadsworth Center has confirmed this test result, which is the first known case of locally acquired Chikungunya in New York State. Given the much colder nighttime temperatures, the current risk in New York is very low." State Health Commissioner Dr. James McDonald said. "We urge everyone to take simple precautions to protect themselves and their families from mosquito bites."
Chikungunya is a mosquito-borne disease most common in tropical and subtropical regions. Symptoms include fever and joint pain, headache, muscle pain, joint swelling, or rash. The illness is rarely fatal and most patients recover within a week, though some may experience persistent joint pain. People at higher risk for severe disease include newborns infected around the time of birth, adults aged 65 and older, and individuals with chronic conditions such as high blood pressure, diabetes or heart disease.
In 2025, there have been three additional chikungunya cases outside New York City that were all linked to international travel to regions with active chikungunya infections. Routine mosquito testing conducted by the Department's Wadsworth Center and the New York City Department of Health and Mental Hygiene (DOHMH) has not detected chikungunya virus in any New York mosquito samples to date.
Mosquito activity in New York is declining as cooler fall temperatures begin. The Department reminds all New Yorkers to take precautions to reduce the risk of mosquito bites:
-- Use EPA-registered insect repellents
-- Wear long sleeves, long pants and socks outdoors when possible
-- Remove standing water around homes, such as in flowerpots, buckets and gutters
-- Repair or patch holes in window and door screens to keep mosquitoes out

Abstract
Highly pathogenic avian influenza A(H5) viruses globally impact wild and domestic birds, and have caused severe infections in mammals, including humans, underscoring their pandemic potential. The antigenic evolution of the A(H5) haemagglutinin (HA) poses challenges for pandemic preparedness and vaccine design. Here the global antigenic evolution of the A(H5) HA was captured in a high-resolution antigenic map. The map was used to design immunogenic and antigenically central vaccine HA antigens, eliciting antibody responses that broadly cover the A(H5) antigenic space. In ferrets, a central antigen protected as well as homologous vaccines against heterologous infection with two antigenically distinct viruses. This work showcases the rational design of subtype-wide influenza A(H5) pre-pandemic vaccines and demonstrates the value of antigenic maps for the evaluation of vaccine-induced immune responses through antibody profiles.
