  Abstract In developing countries particularly in field conditions unfavorable environmental conditions, lack of availability of appropriate transport media (TM) and maintenance of cold chain during transport; sample collection , storage, and transportation is more challenging . Considering these facts, five TM out of which three laboratory-based media named phosphate-buffered saline (PBS), 50% glycerol + PBS , and normal saline (NS) and two commercially available media including viral transport medium (VTM), charcoal based viral transport medium (CVTM) were compared to protect infectivity of the H5N1 influenza virus . Spiked fecal sample and allantoic fluid with and without these TM were placed in field simulatory storage and transportation conditions and in every 12 h time interval these samples were tested for virus isolation in embryonated chicken egg inoculation and identification by HA test and RT PCR upto 7 days. Survivability of the virus was detected by calculating the pe...

  Abstract Background :  Lassa fever (LF) is an acute viral hemorrhagic illness endemic to West Africa, with no licensed vaccines or targeted treatments available, highlighting a critical gap in global health preparedness. T cell-mediated immunity plays a central role in viral control and survival. Synthetic DNA vaccines offer a promising strategy to induce both humoral and cellular immunity against LF. Methods :  A Phase 1b, randomized, double-blind, placebo-controlled trial was conducted to assess the safety, tolerability, and immunogenicity of INO-4500 , a DNA vaccine encoding the Lassa virus (Josiah strain) glycoprotein precursor (GPC). A total of 220 healthy adults were randomized to receive either 1 mg or 2 mg of INO-4500 (intervention), or placebo, administered intradermally (ID) followed by electroporation (EP) at Day 0 and Week 4. Safety was evaluated through Week 48. Primary immunogenicity endpoints included humoral and cellular immune responses at multiple time...

  Abstract Infectious diseases are often observed to have different epidemiology in different countries , which arises due to various factors including those that are ecological, socioeconomic, and healthcare-related . Such variability can sometimes be best captured through looking at groups of countries that are similar within-group but variable between-group. In this study we use statistical learning methods to generate data-driven disease-centric groupings of countries rather than those developed for administrative or political reasons by e.g. the WHO, World Bank, and the United Nations. In particular, we apply hierarchical clustering to group countries based on shared disease-relevant characteristics for zoonotic H5N1 influenza . Using statistical methods such as classification and regression trees (CART)-based imputation and dynamic tree cutting, the analysis accounts for missing data and identifies epidemiologically (rather than politically or economically) meaningful cluster...

  Summary Background Given the continued global circulation of monkeypox virus (MPXV), we aimed to assess the long-term clinical consequences of MPXV infection and the continued presence of the virus in saliva, semen, and the anorectum . We also aimed to compare long-term antibody dynamics after MPXV infection with modified vaccinia Ankara–Bavarian Nordic (MVA-BN) vaccination. Methods In this mixed retrospective and prospective cohort study, adults with acute MPXV infection at the Institute of Tropical Medicine (Antwerp, Belgium) were enrolled in a clinical registry (MPX-COHORT) from May 13, 2022, with follow-up at 1 month after infection. On Oct 3, 2022, we initiated a long-term follow-up study (POQS-FU-PLUS) to extend follow-up of people with mpox and to establish a parallel cohort of adults who received MVA-BN vaccination between Aug 3, 2022, and Jan 4, 2023. Participants were eligible for the second cohort if they received two doses of MVA-BN, unless they had previous smallpox ...

  Abstract Bats are associated with some of the most significant and virulent emerging zoonoses globally , yet research and surveillance of bat pathogens remains limited across parts of the world. We surveyed the prevalence and genetic diversity of coronaviruses from bats in Taita Hills, southeastern Kenya , as part of ongoing surveillance efforts in this remote part of eastern Africa. We collected fecal and intestinal samples in May 2018 and March 2019 from 16 bat species . We detected one genus of coronavirus (alphacoronavirus), with an overall RNA prevalence of 6.5% (30/463). The prevalence of coronavirus RNA was 3.8% (9/235) and 11.6% (21/181) for the two most captured free-tailed bat species, Mops condylurus and M. pumilus respectively, with no detections from other bat species (0/90). Phylogenetic analyses based on the partial RNA-dependent RNA polymerase gene and whole genome sequences revealed that the sequences clustered together and were closely related to alphacoronaviru...

  {Excerpt} On Sept 4, 2025, the DR Congo Government and Ministry of Health announced a new Ebola virus disease outbreak in the Bulape health zone (Kasai province), marking the end of over 15 years without any reported cases of Ebola virus disease in this region . As of Sept 14, 2025, there were 35 confirmed Ebola virus disease cases and 16 deaths , representing a case fatality rate of 45·7%.1,2 This unexpected resurgence in a region with insufficient preparedness capacity raises serious concerns about potential regional spread, including towards neighbouring Angola. At the same time, DR Congo is experiencing one of the most severe cholera outbreaks of the past decade , with a total of 48 139 cases and 1443 deaths reported between Jan 1 and Aug 24, 2025, resulting in a case fatality rate of 3%.3 By epidemiological week 33, high case fatality rates were reported in the provinces of Kwilu (76 cases, 26 deaths; 44%), Sankuru (42 cases, 6 deaths; 14%), and Equateur (224 cases, 19 death...

  Abstract The current panzootic of high pathogenicity avian influenza (HPAI) H5N1 has been catastrophic for wildlife , and following a significant sweep, clade 2.3.4.4b is found in every region aside from Oceania . Herein, we report the results of our third year of targeted surveillance of incoming migratory seabirds and shorebirds into Australia . We did not find evidence of HPAI H5N1 in any of the birds tested , and there were no reports of HPAI H5N1 in wildlife tested through other surveillance schemes in 2024. Unlike previous years, we detected a diversity of low pathogenicity avian influenza (LPAI) viruses in shorebirds. Through phylogenetic analysis we revealed that the H3N7 and H4N7 viruses recovered from Red-necked Stints were complex mosaic viruses, comprising segments of Eurasian, Australian shorebird, and Australian waterfowl segments . A H1N7 virus detected comprised a wholly Eurasian introduction , confirming this route for avian influenza viruses into Australian ecos...

  Significance The high-resolution cryo-EM structure indicates that the human antibody 6Y13 binds strongly to a conserved pan-H7 epitope on the hemagglutinin head , distinct from the receptor-binding site and lateral patch. However, 6Y13 can broadly neutralize H7 viruses , fully protect H7N9 -infected mice, and potently block receptor binding through mechanisms, independent of Fc-mediated steric hindrance. Abstract Zoonotic H7N9 avian influenza virus infection remains a global concern because of its pandemic potential . Therefore, developing effective antibodies and vaccines against H7N9 is vital for preventing and controlling major outbreaks . Here, we isolated a human VH3-30 gene-encoded antibody , designated 6Y13 , from a survivor of H7N9 infection . This antibody recognized the hemagglutinins (HAs) of the representative H7 subtype zoonotic viruses spanning two decades of antigenic evolution and potently neutralized epidemic H7N9 viruses in vitro. Moreover, 6Y13 conferred comple...

  Abstract Samples collected from two avian influenza outbreaks in Bagmati Province in central Nepal between January and March 2023 were positive for H5N1 . Full genomes were generated for both viruses, which revealed that one of the viruses was very similar to clade 2.3.4.4b H5N1 identified in Bangladesh in 2021/2022. The second virus was a reassortant H5N1 virus consisting of four genes (HA, NA, NP, and M) originating from a clade 2.3.2.1a H5N1 and the remaining four genes (NS, PB1, PB2, and PA) originating from a 2.3.4.4b H5N1 . Notably, this second virus had a high identity with 2.3.2.1a clade viruses identified in humans and cats in India in 2024–2025. These are the first full genome sequences of H5N1 avian influenza viruses from Nepal and given the recent human infections by 2.3.2.1a H5N1 viruses in the region, these data will be of interest to both public health and veterinary authorities.
