Adenovirus infections are viral diseases caused by viruses belonging to the adenovirus group. These viruses can affect various organ systems, including the respiratory, digestive, ocular, and urinary tracts. Particularly prevalent in individuals with weakened immune systems, children, and adults, these infections can spread rapidly through different transmission routes and, in some cases, lead to serious health problems.

Over 88 types of adenoviruses are known to infect humans. Unlike influenza viruses, adenoviruses do not exhibit strong seasonality and can remain active throughout the year. They most commonly affect the respiratory and intestinal systems.

Symptoms of adenovirus infection often resemble those of a common cold; primary symptoms include sore throat, nasal and ocular discharge, sneezing, headache, cough, and fever. While some cases may lead to croup or bronchitis, various other clinical presentations such as conjunctivitis (red eye), skin rash, diarrhea, and bladder infections can also be observed.
