Adenoviruses are common viruses that infect the membrane or tissue linings of the eyes, intestines, urinary tract, respiratory tract, and the nervous system. These viruses cause common mild symptoms such as fever, headaches, colds, coughs, sore throats, and pink eye. Adenovirus infection is commonly occurring in children especially in babies and young children, with most having at least one type of infection before the age of 10. It can also occur in adults. Usually, infections caused by adenoviruses result in only mild symptoms and the person infected can get better on their own. However, the symptoms can become severe for people with weak immune systems. These viruses are commonly found in places where there is a large group of children like the school, daycare, and playgrounds. Transmission of these viruses is very contagious since it can spread when droplets containing the virus as a result of coughing or sneezing fly into the air and land on surfaces. When a child touches someone with the virus or touches something held by them and then touches his or her face specially the mouth, nose, and eyes, he or she can catch the virus.
