Adenovirus infection is self-limiting and usually resolves in about 1 week. Adenovirus is widely found in nature, and when the body’s immunity is reduced, adenovirus infection is likely to occur, which can lead to many forms of disease, including acute upper respiratory tract infection, pneumonia, conjunctivitis, gastroenteritis, acute hemorrhagic cystitis, and encephalitis. Patients with adenovirus infection have no specific antiviral drugs, early application of ribavirin or interferon may have a certain effect, usually symptomatic supportive treatment, combined with bacterial infection requires appropriate application of antibiotic therapy. At the same time, because adenovirus infection is self-limiting, most patients can be cured in about 1 week through standard treatment. In addition, patients need to rest in bed, keep the air circulating in the room, eat a light diet, maintain a balanced application, and replenish water and vitamins while undergoing treatment.
