Adenovirus is a common virus that can cause a wide range of illnesses, affecting people of all ages. While it usually causes mild symptoms, in some cases—especially among infants, older adults, or those with weakened immune systems—it can lead to more serious health issues.
What Is Adenovirus?
Adenoviruses are a group of viruses that can infect the lining of your eyes, airways, lungs, intestines, urinary tract, and nervous system. There are more than 50 types of adenoviruses that can affect humans.
Common Symptoms
The symptoms depend on the part of the body that is infected:
•Respiratory tract:
•Cough
•Runny nose
•Sore throat
•Fever
•Pneumonia (in severe cases)
•Digestive tract:
•Diarrhea
•Vomiting
•Abdominal pain
•Eyes (conjunctivitis):
•Redness
•Tearing
•Itchiness
•Urinary tract:
•Pain during urination
•Blood in urine (rare)
How It Spreads
Adenovirus spreads easily through:
•Close contact (e.g., shaking hands)
•Airborne droplets (from coughs and sneezes)
•Contaminated surfaces
•Water (e.g., swimming in poorly chlorinated pools)
It can live on surfaces for a long time and is resistant to many common disinfectants.
Who Is at Risk?
•Children in daycare or school
•Military recruits
•People with weakened immune systems
•Hospitalized patients
Diagnosis and Treatment
There’s no specific cure for adenovirus. Doctors may recommend:
•Rest
•Fluids
•Over-the-counter meds to reduce fever or relieve pain
Antiviral drugs may be used in severe cases, especially in people with weak immune systems.
Prevention Tips
•Wash your hands regularly.
•Avoid touching your face.
•Disinfect surfaces often.
•Keep distance from those who are sick.
•Avoid swimming in unclean pools.
There’s a vaccine for some types of adenovirus, but it’s mainly used in the military, not for the general public.
Final Thoughts
Adenovirus is common and usually mild, but it can be serious in some cases. Good hygiene is your best defense. If symptoms become severe or unusual, especially in young children or elderly adults, seek medical help immediately.
