The most common Human Adenoviruses are types 4 and 7. These two types account for more than 90% of all human adenovirus infections. Other adenoviruses that can cause human infection include types 1, 2, 3, 5, 6, 8, 9, 10, 11, 12, and 14.
Signs and Symptoms of Adenovirus Infection
Adenovirus infection typically causes mild to moderate upper respiratory symptoms. These can include sore throat, runny or stuffy nose, congestion, cough, and sometimes fever. In some cases, the virus can cause eye infections, which may lead to conjunctivitis or pink eye. Gastrointestinal symptoms can also occur, including diarrhea, abdominal pain, and vomiting.
Complications of Adenovirus Infection
In rare cases, adenovirus infection can lead to more serious complications, such as pneumonia, encephalitis, and meningitis. It can also cause urinary tract infections, bronchiolitis, and even death in very rare cases.
Treatment for Adenovirus Infection
Most cases of adenovirus infection can be treated by getting plenty of rest, drinking fluids, taking medications to reduce fever, and using over-the-counter medications to relieve symptoms. In more severe cases, antiviral medications may be prescribed. Vaccines are currently available for some types of adenoviruses.
