Adenovirus is a common respiratory virus. At present, there are more than 50 kinds of adenovirus that can infect human body. Adenovirus infection can cause fever respiratory tract infection, conjunctival fever, keratoconjunctivitis, urinary system infection and gastrointestinal inflammation. Severe disseminated gonadal virus infection can occur in patients with low immune function.

The spread of adenovirus can invade the human body through respiratory tract, digestive tract and conjunctiva, and it can be popular among dense people, such as troops, hospitals, technical schools, orphanages and public swimming pools. Bad hygiene habits can promote the spread of adenovirus, and the incubation period after infection is 2- 14 days, depending on the virus serotype and its transmission route.

Adenovirus is a common virus that easily infects respiratory tract, gastrointestinal tract, urinary system and other organs. The symptoms of adenovirus infection are very similar to influenza, including fever, cough, runny nose and other symptoms, contact infection and droplet infection. Common diseases include respiratory tract infection, rhinitis and epidemic keratitis. Hemorrhagic cystitis is the most common gynecological disease, most of which are caused by adenovirus 1 1 and 2 1.

Adenovirus infection can occur all year round, but mostly in winter and spring. Adenovirus infection can lurk in lymphoid tissue, renal parenchyma or other tissues, and can activate infection under immunosuppression. Various serotypes can cause different diseases. Pregnant women and immunocompromised patients may have obvious symptoms after infection, which can be life-threatening in severe cases.
