One of the most common viruses that affects children is adenovirus. It infects the mucus membranes and can cause illness in the respiratory tract. “Adenovirus accounts for about 10-percent of respiratory infections, which doesn’t sound like a lot, but is a huge amount,” says pediatrician Dr. Sue Hubbard.
Adenovirus can cause conjunctivitis (pink eye), sore throat, cough, GI problems like diarrhea, vomiting, cramping and even blood in the urine. However, Dr. Hubbard cautions that the symptoms vary from person to person.
