Adenovirus is a common virus that can cause a wide range of illnesses, from mild respiratory illnesses to severe, life-threatening conditions such as pneumonia and gastroenteritis. While the virus typically resolves on its own within a week or two, it can have long-term effects in some individuals.
In the long term, adenovirus infections can cause chronic inflammation and scarring of the lungs, which can lead to breathing difficulties, as well as chronic fatigue. They can also cause chronic eye infections, which can lead to vision loss or blindness. In some cases, adenovirus can cause chronic inflammation and scarring of the heart, which can lead to heart failure. Adenovirus can also cause chronic gastrointestinal issues, including inflammation of the intestines, which can lead to persistent diarrhea and abdominal pain.
In addition, adenovirus can cause long-term complications in people with weakened immune systems, such as those with HIV/AIDS or who are undergoing chemotherapy. In these individuals, adenovirus can cause serious and life-threatening illnesses, such as meningitis, encephalitis, or pneumonia.
The best way to prevent long-term effects from adenovirus is to practice good hygiene habits, such as washing your hands often, avoiding close contact with people who are ill, and getting vaccinated.
