What Is Mononucleosis?
2. Causes
The Epstein-Barr virus is the most common cause of mononucleosis. Some other types of virus can also cause the same symptoms, however. The virus is known also as the kissing disease because it is usually found in saliva, thus kissing is a common method of transmission. It can also be caught when sharing items like cutlery and drinking vessels.
Mononucleosis can be caught by people of all ages, but adolescents are most at risk. Adults are less likely to be affected by the disease because they have already likely been exposed to the virus. This will mean that their immune system is better prepared to protect them from the virus.
