Overview
- UKHSA reports week‑51 adenovirus test positivity around 1.7% in England, rising to about 9.9% in children under five, with recent declines after earlier increases.
- Clinicians describe infections that can involve the respiratory tract, eyes and gastrointestinal system, and note some cases can linger for six to eight weeks.
- Health guidance emphasizes symptomatic care because no widely used vaccine or targeted antiviral exists for adenovirus infections.
- Officials recommend hygiene steps such as covering coughs and sneezes, frequent handwashing and improving ventilation to limit spread via droplets, contact and contaminated surfaces.
- Neighboring countries say influenza A, particularly H3N2, is the main driver of their winter waves, with Germany’s RKI and Austrian centers reporting adenovirus as a minor factor.
