  {Excerpt} Risk statement This risk assessment is based on the current epidemiological and epizootic situation of Rift Valley fever (RVF) in Senegal and Mauritania , from 20 September through 8 October 2025. The risk assessment was conducted separately for each country . However, the findings indicate that the level of risk is the same for both countries across all levels, for both human and animal health .   During this period , Senegal reported 119 confirmed human RVF cases , including 16 deaths , resulting in a case fatality rate (CFR) of 13.4% . Cases were recorded across eight health districts in three regions of Senegal, with the majority in Saint-Louis Region with 110 cases (92%) followed by Louga (four cases) and Matam (one case).  The affected districts in Saint-Louis Region : Podor, Richard-Toll, Dagana, and Saint-Louis are located along the northern border with Mauritania along the Senegal River.   The most affected age groups were 15- 35 years ...

  Summary Background Since October, 2023, Palestinian children in the Gaza Strip have suffered war-induced displacement, food insecurity, malnutrition, and elevated risks of famine and mortality . In this study, we aimed to document the extent of, and patterns in, wasting malnutrition in children aged 6–59 months across the Gaza Strip between January, 2024, and August, 2025. Methods This longitudinal, cross-sectional, surveillance study was conducted across a total of 16 UN Relief and Works Agency for Palestine Refugees in the Near East health centres and 78 medical points established within school shelters and tent encampments across the five governorates of Gaza. Children aged 6–59 months were screened for wasting malnutrition by mid-upper arm circumference (MUAC) measurement. Children with a MUAC of less than 125 mm were enrolled into therapeutic feeding regimens. MUAC Z scores were derived from published WHO age-specific and sex-specific arm circumferential growth curves. Month...

  Abstract Greece is one of the countries in Europe most affected by West Nile virus (WNV), and since 2010, when the virus caused a large outbreak with 197 human neuroinvasive cases , outbreaks occur almost every year. Mosquito surveillance is an indirect sign of virus circulation; therefore, the purpose of the study was the molecular detection of WNV in 45,988 C. pipiens s.l. mosquitoes collected during 2024 in four Regions of Greece and the genetic characterization of the virus strains. WNV was detected in 41 of 1316 ( 3.12% ) Culex spp. mosquito pools . Next-generation sequencing was applied to the WNV-positive samples that had a high viral load . All WNV sequences belong to Cluster B of the sub-lineage Europe WNV-2A presenting a temporal clustering. The WNV infection rates varied highly across the Regions, regional units and months, being higher in Thessaly and Central Macedonia Regions , especially in July and September. All mosquito pools were also tested for Usutu virus (USU...

  {Excerpts} To the Editor : After a decade of no reported human cases, Cambodia faces a resurgence of highly pathogenic avian influenza (HPAI) A(H5N1) virus infections , with an overall mortality of 38%. Cases have occurred primarily in children and adolescents who were exposed to infected poultry (...). From February 2023 through August 2024, a total of 16 infections were detected through the long-standing national influenza-like illness and severe acute respiratory infection surveillance systems, both of which were strengthened by expanded laboratory-testing capacity that was developed during the coronavirus disease 2019 pandemic. All 16 patients reported exposure to sick or dead poultry , and outbreak investigations identified contemporary, genetically similar viruses in poultry collected in or around case households or from active, longitudinal surveillance of live-bird markets . Genomic sequencing revealed an avian origin for all the human infections , and sequences have been...

  ABSTRACT Common cold coronaviruses, such as OC43 and HKU1, typically cause mild respiratory infections in healthy people. However, they can lead to severe illness in high-risk groups , including immunocompromised individuals and older adults. Currently, there is no clinically approved vaccine to prevent infection by common cold coronaviruses. Here, we developed an mRNA vaccine expressing a stabilized spike protein derived from OC43 coronavirus and tested its efficacy in different challenge models in C57BL/6 mice . This novel OC43 vaccine elicited OC43-specific immune responses, as well as cross-reactive immune response against other embecoviruses , including HKU1 and mouse hepatitis virus (MHV-A59). Interestingly, this OC43 vaccine protected mice not only against a lethal OC43 infection but also against a distant embecovirus, MHV-A59. These findings provide insights for the development of common cold coronavirus vaccines, demonstrating their potential to protect against various c...

  Abstract Background :  The purpose of this study was to retrospectively analyse the clinical presentation of RSV, Influenza , and SARS-CoV-2 infections in children across three consecutive seasons (2022/2023; 2023/2024; and 2024/2025).  Methods :  Of the 321 hospitalised patients , 129 ( 36% ) tested positive for RSV , 110 ( 38% ) for Influenza , and 82 ( 26% ) for SARS-CoV-2 . Children were aged ≤ 17 years (median: 15 months). The data were statistically analysed using the χ2 test, multinomial multivariable logistic regression, OR (odds ratio), and 95% CI (confidence interval).  Results :  Significant independent predictors of RSV infection were auscultatory abnormalities (OR: 15.9 [1.49–169]) and hospital admission ≥ 4 days after symptom onset (OR: 32.5 [1.19–907]). Among RSV-positive patients , compared with those aged < 6 months , those aged 7–24 months were more likely to present with higher CRP levels (OR 1.06 [1.003–1.13]), reduced appetite (OR ...

{ob1-Shiraoi-Town} On 21 October 2025, a Livestock Hygiene Service Centre (LHSC) in Hokkaido Prefecture received a notification from a domestic layer farm regarding an increase in bird mortality. Samples were collected from birds on the farm by LHSC officers and tested positive for influenza A virus using a viral antigen rapid test. On 22 October, the LHSC conducted RT-PCR and rRT-PCR tests and confirmed that the virus is of high pathogenicity . Movement and shipment restriction have been imposed on farms within a radius of 3 km and 10 km of the affected farm, respectively. Stamping-out and relevant control measures, including disinfection, are ongoing. The National Institute of Animal Health (NIAH) is sequencing the virus genome and will identify the subtype.

  Abstract The H7N9 influenza viruses, which are capable of causing severe respiratory syndrome in humans , were first discovered to infect humans in 2013 and continue to pose a persistent public health threat . Quail has been proposed as a potential intermediate host that may facilitate the emergence of novel reassorted influenza A viruses with the capacity to infect humans across species barriers; however, information on the biological characterization of quail H7N9 remains limited. In this study, we isolated and identified an avian H7N9 influenza virus from quails , designated as A/quail/Hebei/CH06-07/2018 (H7N9) and abbreviated as CH06-07, in Hebei, China . Phylogenetic analyses revealed that both the HA gene and the NA gene of CH06-07 were clustered in the Eurasian lineage . Furthermore, CH06-07 exhibited binding affinity for both α2,3-linked and α2,6-linked sialic acid receptors and demonstrated high pathogenicity in both quails and mice . Notably, transmission studies reveal...

  Abstract Background :  The COVID-19 pandemic , driven by the SARS-CoV-2 virus, has become an unprecedented global public health challenge . Comprehensive investigation of the virus transmission dynamics requires exploration of all potential routes , including the role of animal reservoirs . This study aimed to assess the presence of SARS-CoV-2 RNA and antibodies in urban rodents captured within two landscape units (low-income neighborhoods and green spaces) in the metropolitan area of Buenos Aires (MABA), Argentina. Methods :  Between July 2020 and September 2022, 125 synanthropic rodents (68 Rattus norvegicus, 22 R. rattus, and 35 Mus musculus) from seven low-income neighborhoods and seven green spaces in the MABA were captured and examined for SARS-CoV-2 exposure and infection by indirect immunofluorescence serology and RT-qPCR, targeting the N, E, and ORF1ab genes. Results :  Two M. musculus and six R. norvegicus from five different low-income neighborhoods test...
