Overview

• Human metapneumovirus (HMPV) cases are surging in China and showing a slight increase in the UK, particularly among children under five and adults over 80.
• HMPV is a well-known seasonal respiratory virus, first identified in 2001, causing cold or flu-like symptoms that are typically mild for most people.
• The UK Health Security Agency (UKHSA) reports that 5% of recent hospital swabs in England tested positive for HMPV, marking the highest rate this winter but still within expected seasonal levels.
• Experts stress that HMPV lacks pandemic potential due to its long-established presence, global immunity, and absence of significant mutations or animal reservoirs.
• Health officials recommend standard precautions like handwashing, mask-wearing for symptomatic individuals, and limiting contact with vulnerable populations to reduce transmission.
