  ABSTRACT Swine acute diarrhea syndrome coronavirus (SADS-CoV) is a bat-originated virus causing severe diseases in piglets . Since the 2016 outbreak , diverse SADS-related CoVs (SADSr-CoVs) have been detected in Rhinolophus bats in China and Southeast Asia , but their potential interspecies infection and pathogenicity remain unknown. Herein, we sequenced the spike (S) genes of bat SADSr-CoVs and classified them into four genotypes . We constructed an infectious SADS-CoV cDNA clone (rSADS-CoV) and nine recombinant viruses by replacing the SADS-CoV S gene with that of bat SADSr-CoVs. Recombinant SADSr-CoVs could replicate efficiently in respiratory and intestinal cell lines and human- and swine-derived organoids and caused varying tissue damage and mortality in suckling mice. These viruses can be classified into at least five serotypes based on cross-neutralization assays . Our findings highlight the potential risk of interspecies infection and provide important information for fut...

  Abstract SARS-CoV-2 Spike - the sole neutralization target, is highly resilient to the immune pressure driving genetic evolution . While potency and breadth of neutralization are widely studied, the incomplete neutralization - the mechanism of resistance without needing genetic change - remains unexplored . Several monoclonal antibodies , although potent, showed incomplete neutralization of genetically homogeneous pseudovirus suggesting the existence of distinct spike conformations . The residual infectivity at high antibody concentration indicates a viral fraction with intrinsic resistance to the antibody. Although the published studies on spike glycosylation, structure, and conformations provide evidence of spike heterogeneity the precise mechanism for the incomplete neutralization has not been established. In this study, we devise a method to separate the un-neutralized virion population , called as persistent fraction of infectivity (PF), and characterize the viral spike prot...

  ABSTRACT With the SARS-CoV-2 Omicron XBB.1.9 subvariants circulating worldwide, two XBB.1.9 variants, EG.5.1 and HK.3 , spread rapidly and became dominant in mid-2023. However, the spike features, pathogenicity, and transmissibility of HK.3 are largely unknown. Here, we performed multiscale investigations to reveal the virological features of XBB.1.9 subvariants , including the newly emerging HK.3 . HK.3 revealed high replication efficiency and enhanced TMPRSS2 utilization in vitro. The HK.3 spike exhibited enhanced processing, although its infectivity, fusogenicity, and human ACE2 (hACE2) binding affinity were comparable to those of the EG.5 and XBB.1 spikes. All XBB.1.9.1, EG.5.1, and HK.3 strains demonstrated efficient transmission in hamsters , although XBB.1.9.1 exhibited stronger fitness in the upper airways . XBB.1.9.1, EG.5.1, and HK.3 exhibited greater pathogenicity than BA.2 in H11-K18-hACE2 hamsters. Our studies provide insights into the newly emerging pathogens EG.5.1...

  Significance Annual influenza epidemics in the United States cause hundreds of thousands of hospitalizations . Quantifying vaccine impact is vital, yet many analyses overlook vaccines’ dual benefits : directly protecting recipients and indirectly protecting their contacts . Using a mathematical model that accounts for both effects, we estimate that vaccination prevented about 70,000 hospitalizations during the 2022–2023 season , with another 19,000 potentially avoidable if coverage met the 70% national target. Despite uncertainty in vaccine effectiveness against infection, our findings suggest that vaccinating younger adults offers substantial indirect protection for older adults. Tailoring annual vaccination campaigns by age group and state could further strengthen their public health impact. Abstract During the COVID-19 pandemic early years, infection prevention measures suppressed transmission of seasonal influenza and other respiratory viruses . The early onset and moderate s...

  Abstract Background Plague, a zoonosis caused by Yersinia pestis, is endemic in Madagascar but knowledge on the epidemiological situation in the northern focus remains unclear . The aim of this study was to investigate the circulation of Y. pestis in terrestrial small mammals in north eastern Madagascar, where suspected plague outbreaks have been reported. Methods Sampling of terrestrial small mammals and their fleas was carried out in 22 trapping sites within 9 localities of the two sectors (1 and 3) of Makira Natural Park (MNP) and surroundings, from 2020 to 2022. Yersinia pestis was investigated in terrestrial small mammal spleen samples and their fleas using bacteriological, serological and molecular methods. Results A total of 614 terrestrial small mammals composed of eight species and 1,754 individual fleas were collected following 4,880 trap-nights. The black rat (Rattus rattus) represented the majority (87.8%) of the small mammal species caught. Flea infestation rate was ...

  Phnom Penh, November 16 (Xinhua) -- Cambodia's Ministry of Health confirmed on the 16th that a young man residing in Phnom Penh had died from avian influenza (H5N1). Authorities urged the public to be vigilant and take effective preventative measures. According to the report, the 22-year-old man experienced severe symptoms including fever, cough, shortness of breath, and difficulty breathing . Despite the medical team's best efforts, his condition rapidly deteriorated, and he died on the 15th of this month . This is the first reported human death from avian influenza in the country's capital this year. Following the incident, the Cambodian Ministry of Health immediately activated its emergency response mechanism . Local professional teams are conducting a comprehensive and detailed epidemiological investigation to trace the source of infection and identify close contacts .

  Summary Background First discovered in 1999 in Malaysia, Nipah virus (NiV) causes yearly outbreaks throughout south and southeast Asia with associated mortality rates of 40–75 %. Due to the structural and sequence similarities between the NiV and Hendra virus (HeV) attachment G glycoproteins , and the extensive extant evidence of the ability of a recombinant soluble glycoprotein G (HeV-sG) to provide heterologous cross-protective immunity when used as vaccine (HeV-sG-V), this study aimed to evaluate HeV-sG-V for safety, tolerability, and immunogenicity against NiV. Methods We conducted a phase 1, single-centre, randomised, observer-blind, placebo-controlled study . Eligible participants were aged 18–49 years, healthy, and not pregnant; participants were ineligible if they were immunocompromised, had received blood products within 6 months of enrolment, had potential exposure to NiV or HeV, or had known allergies to components of the vaccine. Participants were randomly assigned in...

  14 November 2025 Addis Ababa—Ethiopia’s Ministry of Health has confirmed an outbreak of Marburg virus disease in the South Ethiopia Region, the first of its kind in the country , following laboratory testing of samples from a cluster of suspected cases of viral haemorrhagic fever. Genetic analysis by the Ethiopia Public Health Institute revealed that the virus is of the same strain as the one that has been reported in previous outbreaks in other countries in East Africa .  A total of nine cases have been reported in the outbreak that has affected Jinka town in the South Ethiopia Region. The national authorities are scaling up response including community-wide screening, isolation of cases, treatment, contact tracing and public awareness campaigns to curb the spread of the Marburg virus, which is in the same family of viruses that cause Ebola virus disease. The World Health Organization (WHO) and partners are supporting the government as it intensifies response to halt the sp...
