Adenoviruses are a type of virus that can cause a wide range of illnesses, from the common cold to more serious illnesses such as bronchitis, pneumonia, and even gastroenteritis. Adenoviruses are the most common cause of infectious conjunctivitis (pink eye) and can also cause acute respiratory illnesses, such as croup and bronchiolitis.
Adenoviruses are spread through contact with an infected person's bodily fluids, such as saliva, mucus, and stool. People can also get infected by touching contaminated objects or surfaces, or by breathing in droplets from an infected person's cough or sneeze. The incubation period for adenovirus infections typically ranges from two to fourteen days.
Adenoviruses are one of the most common causes of respiratory infections in young children, but they can also affect adults. Symptoms of adenovirus infection are similar to those of the common cold, including runny nose, sore throat, cough, and fever. Other symptoms may include conjunctivitis, diarrhea, and abdominal pain. More serious adenovirus infections may cause pneumonia, bronchitis, or inflammation of the stomach and intestines.
Adenovirus infections can be prevented by practicing good hygiene, such as washing hands often and avoiding contact with people who are sick. Vaccines are also available to protect against some types of adenoviruses. Treatment for adenovirus infections generally involves managing symptoms with rest and fluids. In more serious cases, antiviral medications may be prescribed.
