Serious adenovirus can last anywhere from a few days to several weeks, depending on the severity of the infection. In most cases, mild infections can resolve on their own within two weeks. Serious infections may require hospitalization and additional treatments, such as antibiotics or antivirals, to help fight the virus and reduce the severity of symptoms. Additionally, some people may experience symptoms for up to six months after the initial infection.
Common symptoms of adenovirus infections include fever, sore throat, cough, wheezing, runny nose, and swollen lymph nodes. In more serious cases, it can cause difficulty breathing, pneumonia, and inflammation of the eyes, heart, and intestines. People with weakened immune systems, such as those with HIV/AIDS, may be more susceptible to serious adenovirus infections.
If you think you or someone in your family may have a serious adenovirus infection, it’s important to seek medical attention. Your doctor may order blood tests, chest x-rays, and other tests to diagnose the infection and determine the best course of treatment. Treatment for more serious adenovirus infections may include intravenous fluids, antibiotics, and antiviral medications.
In general, adenovirus infections tend to be more severe in infants and young children, people with weakened immune systems, and people who haven’t been vaccinated. It’s important to take steps to reduce your risk of infection, such as washing your hands and avoiding close contact with people who are sick. Additionally, the CDC recommends getting the adenovirus vaccine if you are at increased risk of serious infection.
