  Abstract Since early-2024 unprecedented outbreaks of highly pathogenic avian influenza H5N1 clade 2.3.4.4b have been ongoing in dairy cattle in the United States with significant consequences for the dairy industry and public health . Estimation of key epidemiological parameters is required to support outbreak response , including predicting the likely effectiveness of interventions and testing strategies . Here, we pool limited publicly available data from four studies of naturally and experimentally infected dairy cattle. We quantify Ct value trajectories of infected dairy cattle and the relationship between Ct value and the log-titer of infectious virus , a proxy for infectiousness . We estimate that following infection minimum Ct values are rapidly reached within 1–2 days with a population mean Ct value of 15.7 (12.9, 18.4). We identify a threshold Ct value of 21.8 (19.9, 24.6), with values of Ct value above this threshold representing little-to-no infectious viral load . Fin...

  Abstract Highly pathogenic avian influenza H5N1 viruses of clade 2.3.4.4b have caused widespread avian mortality and sporadic mammalian infections , raising concerns about their potential for efficient replication in the human population . Efficient replication in the human upper respiratory tract is considered a key barrier to transmission . Here, we demonstrate that an H5N1 virus isolated from bovine milk in Texas in 2024 (H5N1Tex/24) replicates as efficiently as the 2009 pandemic H1N1 virus (H1N1HH4/09) in well-differentiated human nasal epithelial cells . These cells express both avian- and human-type influenza receptors , indicating receptor adaptation is unnecessary for entry . H5N1Tex/24 replicates effectively at 33 degrees Celsius , reflecting nasal cavity temperature , whereas earlier avian H5N1 strains require 37 degrees Celsius, suggesting that H5N1Tex/24 has acquired another key adaptive feature to the human upper respiratory tract. H5N1Tex/24 remains sensitive to int...

  Abstract In 2024, an unprecedented outbreak of H5N1 high pathogenicity avian influenza was detected in dairy cattle in the USA resulting in spillbacks into poultry, wild birds and other mammals including humans . Here, we present molecular and virological evidence that the cattle B3.13 genotype H5N1 viruses rapidly accumulated adaptations in polymerase genes that enabled better replication in bovine cells and tissues , as well as cells of other mammals including humans . We find evidence of several mammalian adaptations in cattle including PB2 M631L , which is found in all cattle sequences, and PA K497R , which is found in the majority. Structurally, PB2 M631L maps to the polymerase-ANP32 interface , an essential host factor for viral genome replication. We show that this mutation adapts the polymerase to better interact with bovine ANP32 proteins , particularly ANP32A, and thereby enhances virus replication in bovine mammary systems and primary human airway cultures . We show th...

  Abstract Previous studies have documented an increased risk for thrombotic events 30 days after COVID-19 infection , but less is known about this risk beyond 30 days or compared with risk after other infectious acute respiratory illnesses (ARIs). By using PCORnet data from April 1, 2022–April 30, 2023 , we compared the incidences of thrombotic events in the year after COVID-19 illness with other ARI diagnoses in hospitalized and nonhospitalized patients. Overall, the risk for any thrombotic event was higher among patients with COVID-19 compared with patients with other ARIs (incidence ratio 1.63; p<0.05). Nonhospitalized patients with COVID-19 had a 73% increased risk for a thrombotic event in the year after acute illness compared with nonhospitalized patients with ARI (p<0.05). The increased risk for thrombotic events in the year after COVID-19 emphasizes the need for stroke awareness for patients and healthcare professionals. Source:  Link:  https://wwwnc.cdc.go...

  Abstract Human non-polio enteroviruses (NPEVs) cause a plethora of infections in humans, ranging from mild to severe neurological diseases including aseptic meningitis . NPEVs are the leading cause of aseptic meningitis in both children and adults worldwide . In Russia , reports of NPEV infections have surged, especially in the post-COVID era starting in 2022, with elevated infection rates into 2023 . A comprehensive examination of the whole genome is crucial for understanding the evolution of NPEV genes and for predicting potential outbreaks. This study focused on identifying the circulating NPEV strains in the Ural Federal District and Western Siberia , using Sanger sequencing and next-generation sequencing (NGS) methodologies. Biological samples were collected from (n = 225) patients diagnosed with aseptic meningitis. Bioinformatics analysis targeted the nucleotide sequences of the major capsid protein (partial VP1) gene fragment, and the assembly of whole NPEV genomes. A tota...

  Abstract Influenza A viruses exhibit broad host tropism, infecting multiple species including humans, avian species, and swine. Swine influenza virus (SIV), while primarily circulating in porcine populations , demonstrates zoonotic potential with sporadic human infections . In this investigation, we identified two H1N1 subtype swine influenza A virus strains designated A/swine/China/SD6591/2019(H1N1) (abbreviated SD6591) and A/swine/China/SD6592/2019(H1N1) (abbreviated SD6592) in Shandong Province , China. The GenBank accession numbers of the SD6591 viral gene segments are PV464931-PV464938, and the GenBank accession numbers corresponding to each of the eight SD6592 viral gene segments are PV464939-PV464946. Phylogenetic and recombination analyses suggest potential evolutionary differences between the isolates. SD6591 displayed a unique triple-reassortant genotype : comparative nucleotide homology assessments demonstrated that the PB2, PB1, NP, NA, HA, and NEP genes shared the hi...

  Abstract Annual influenza vaccination is the cornerstone for seasonal protection, yet antibody responses are highly variable across individuals and over time. To systematically assess the determinants of this heterogeneity, we compiled 20,449 hemagglutination inhibition and neutralization titers from 4,540 participants enrolled in 14 new vaccine studies we conducted and 50 prior studies that collectively span 2010-2023. Seasonal effects dominated , with pre- and post-vaccination titers declining steadily from 2017 onwards, outweighing the influence of age, sex, or repeated vaccination. Titers to B Yamagata remained steady throughout all years examined, suggesting unique durability and offering a reason for lineage extinction . Vaccine timing emerged as a strong and previously underappreciated determinant of immunity, with individuals vaccinated later in the season exhibiting larger post-vaccination titers . Not being vaccinated or receiving the live-attenuated FluMist vaccine in ...

  Abstract Influenza causes substantial morbidity and mortality worldwide. This randomized, open-label, phase 1 trial (ClinicalTrials.gov, NCT05397223, date of registration: May 31, 2022) compared the immunogenicity of an mRNA-based quadrivalent influenza hemagglutinin (HA) vaccine (mRNA-1010) with a licensed comparator (FLUAD) in adults aged 18-75 years . We evaluated humoral and cellular immune responses using hemagglutination inhibition assays , flow cytometry-based memory B cell (MBC) profiling, and intracellular cytokine staining for T-cell characterization. Both vaccines elicited durable hemagglutination inhibition titers and increased HA-specific MBC responses across four vaccine strains. Compared with FLUAD, mRNA-1010 induced higher frequencies of classical and activated MBCs specific to the H3 HA included in the vaccine, while inducing similar MBC responses to the other strains. mRNA-1010 and FLUAD generated strong HA-specific CD4+ T-cell responses; a trend toward higher C...

  Abstract Marburg virus (MARV) is the primary cause of Marburg virus disease (MVD), a severe hemorrhagic fever with a high case-fatality rate. The first reported MVD outbreak in Tanzania occurred in 2023 , followed by a second outbreak in 2025 , both within the Kagera region . During those MVD outbreaks, 174 suspected cases were identified; of those, 10 were laboratory confirmed. After complete genome assembly and bioinformatic analyses, we found the MARV strains of the 2023 and 2025 outbreaks to be closely related and clustered with MARV strains that caused outbreaks in Rwanda (2024) and Uganda (2014). The sequences from both MVD outbreaks in Tanzania showed >99.71% nucleotide identity, suggesting a possible single spillover event followed by limited human-to-human virus transmission . Further ecologic studies are essential to identify potential spillover events, but our findings indicate that closely related MARV strains circulate in Kagera, Tanzania, posing a risk for future...

  Abstract This study aimed to investigate the prevalence of heart failure (HF) among adults aged ≥ 40 years using health checkup and medical claim data in Fukushima from 2015 to 2021 . Joinpoint regression and age-period-cohort analyses were conducted to estimate temporal trends. Age-standardized prevalence and hospital admission rates for HF were 37.0 and 7.4/1000 and 25.9 and 5.3/1000 for men and women, respectively. The prevalence was significantly higher in the coastal area and evacuation zone designated after the 2011 disaster compared to the prefecture overall. In men, the prevalence increased continuously, with an average annual percentage change (AAPC) ranging from 0.72% (evacuation zone) to 1.15% (mountainous area) (P < 0.05). In total residents, the AAPC was significant only in the mountainous areas (0.78%, P = 0.021). Age-period-cohort analysis showed a net drift of 2.50% (95% CI 1.88–3.13%) in men and 0.76% (95% CI − 0.17–1.70%) in women. Cohort rate ratios increase...
