Causes, incidence, and risk factors
Infection with cytomegalovirus (CMV) is very common. The infection is spread by:
- Blood transfusions
- Organ transplants
- Respiratory droplets
- Sexual contact
Most people are exposed to CMV in their lifetime, but typically only individuals with weakened immune systems become ill from CMV infection. Some people with this condition develop a mononucleosis-like syndrome.
In the U.S., CMV infection most commonly develops between ages 10 - 35. Most people are exposed to CMV early in life and do not realize it because they have no symptoms. People with a compromised immune system can have a more severe form of the disease.
