Overview
- UKHSA reports adenovirus lab positivity in England fell from 1.7% to 1.2% in the week ending 14 December, with the highest rate in under‑fives at 5.7%.
- GPs and pharmacists note more patients with adenovirus‑like illness this winter alongside flu and Covid, reflecting seasonal circulation rather than a new pathogen.
- The CDC lists symptoms ranging from cold‑ or flu‑like illness to conjunctivitis, bronchitis, pneumonia and gastroenteritis, varying by strain and patient.
- Transmission occurs via close contact, respiratory droplets, contaminated surfaces and, in some settings, stool, with clinicians noting the virus can persist in the environment.
- There is no specific antiviral or vaccine; most cases are managed with rest, fluids and over‑the‑counter relief, with hygiene and staying home when unwell advised, particularly to protect young children, older adults and immunocompromised people.
