Causes of Swollen Tonsils
5. Adenoviruses
Adenoviruses are a group of viruses that are often responsible for infections of the eyes, intestines, lungs, nervous system, and urinary tract. They tend to cause symptoms such as a fever, cough, diarrhea, pink eye, sore throats and, of course, inflamed tonsils.
The common cold is a type of adenovirus. Adenoviruses are very common and most people will have been infected by at least one variety by the time they are 10 years old. They do affect children more than adults, but they can affect people of any age. Adenoviruses are usually quite mild, but people who are particularly vulnerable should still be monitored closely.
