Adenovirus symptoms as UKHSA says most infected by age 10.

The UK Health Security Agency says adenovirus is likely to infect most people in the UK before age 10, and infections typically cause mild, cold-like symptoms that appear two days to two weeks after exposure.

The UK Health Security Agency has highlighted adenovirus, noting it is likely to infect most people in the UK by the time they reach age 10. The agency says adenoviruses circulate year-round rather than following a single season and spread easily where people are in close contact. UKHSA describes most infections as mild and similar to the common cold. Key points: - UKHSA says adenovirus commonly infects children and is likely to have infected most people by age 10. - The virus can spread throughout the year and often transmits in settings with close contact, such as schools, hospitals and nurseries. - Symptoms are generally mild and can resemble a cold; they typically appear two days to two weeks after exposure and often last a few days to two weeks. - Adenovirus can be associated with other illnesses, including pneumonia, bronchitis, conjunctivitis, gastroenteritis and ear infections, and may cause more serious illness in people with weakened immune systems. Summary: Most adenovirus infections are reported as mild and usually resolve on their own in otherwise healthy people, though the virus can be linked to other respiratory, eye and gastrointestinal conditions and may be more serious for immunocompromised individuals. Undetermined at this time.
