Weekly epidemiological record   20 MARCH 2026, 101th YEAR, No 12, 2026, 101, 53–56 http://www.who.int/wer   Executive Summary   The WHO Expert Working Group on Surveillance of Influenza Antiviral Susceptibility (AVWG) supports the WHO GISRS by providing practical guidance for monitoring antiviral susceptibility of seasonal and emerging influenza viruses through global surveillance efforts .  The 14th WHO-AVWG meeting was held in virtual format on 10-12 June 2025 .  Update on susceptibility of seasonal influenza viruses to approved antiviral agents   From approximately May 2024 to May 2025 , five WHO Collaborating Centres (CCs) and two National Influenza Centres (NICs) reported co-circulation of influenza A(H1N1) pdm09, A(H3N2), and B/Victoria viruses.  A(H1N1)pdm09 dominated in Eastern Asia {1}. Elevated frequency of influenza neuraminidase (NA) inhibitor (NAI) reduced inhibition/ highly reduced inhibition (RI/HRI) was identified among A(H1N1)pdm09 vir...

  Abstract Background Most studies of human metapneumovirus (HMPV) epidemiology have been among inpatients . This study examined the epidemiology of HMPV compared with other common viruses among outpatients seeking care for an acute respiratory illness (ARI) during 5 influenza seasons (2016–2017 to 2019–2020, before the coronavirus disease 2019 pandemic, and in 2021–2022, during the pandemic). Methods Outpatients ≥6 months old seeking care for ARI and presenting with cough of ≤7 days’ duration provided nasal and pharyngeal swab samples , demographic data, and access to electronic medical record data. Samples were tested with reverse-transcription polymerase chain reaction assays for HMPV , influenza, parainfluenza virus (PIV) 1–4, respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Student′s t and χ2 tests were used to compare HMPV cases with other ARIs. Results After exclusion of 68 coinfections , 7143 patients remained; 2017 had in...
