Mystery Winter Bug? It Could Be Adenovirus
5 Feb
Summary
- Adenovirus causes flu-like symptoms, particularly in winter.
- Vulnerable groups like children and elderly face severe risks.
- Symptoms include fever, sore throat, cough, and red eyes.

Adenovirus, a group of viruses that circulates year-round, sees a sharp increase in cases during winter months. As people spend more time indoors, the virus spreads easily through respiratory droplets and contaminated surfaces. Symptoms often begin mildly, resembling a common cold, and can include fever, a persistent sore throat, cough, and runny nose. Some individuals may also experience conjunctivitis or gastrointestinal issues.
While most healthy adults recover within one to two weeks with rest and fluids, adenovirus poses a significant threat to vulnerable populations, including babies, the elderly, and immunocompromised individuals. In these groups, the virus can lead to severe chest infections, pneumonia, and dehydration, sometimes necessitating hospital care. There is no specific antiviral treatment; care focuses on symptom management.
Prompt medical attention is advised if symptoms worsen, breathing becomes difficult, or a high fever persists. Public health guidance emphasizes regular handwashing, surface cleaning, and self-isolation when unwell to curb the virus's transmission. Health experts urge the public not to dismiss flu-like symptoms, especially for those at higher risk, as they could indicate a more serious condition.
