The UK Health Security Agency reports a record high of human metapneumovirus (HMPV) cases this winter.
In the week ending January 19, 5% of hospital respiratory swabs tested positive for HMPV.
This marks the highest rate this season, surpassing the 4.18% recorded at the start of 2024.
The elderly, particularly those aged 80 and over, are most affected, with a 7.3% positivity rate.
Children under five also show a significant rise, with about 7% testing positive for HMPV.
Doctors advise individuals with respiratory symptoms to wear face masks in public to prevent transmission.
HMPV is a common virus causing cold-like symptoms but can be severe for vulnerable populations.
The virus spreads through direct contact or touching contaminated surfaces.
Health officials urge regular handwashing and proper respiratory hygiene to reduce infection spread.
