CMV stands for Cytomegalovirus, which is a common virus that can cause symptoms similar to mono such as fever, sore throat, and fatigue. It can be especially dangerous for people with weakened immune systems.

Cytomegalovirus (CMV) is a virus related to the group of herpes viruses.

Yes and no. Normally in a person who is relatively healthy, the chances of CMV being fatal are extremely low to none. However if someone with a compromised immune system has CMV it can be quite fatal (IE: HIV).

Past or recent infection with CMV can be identified by antibody tests and CMV can be grown from body fluids.

Cytomegalovirus studies are especially important since CMV has been found to be the carrier for infections in people with compromised immune systems. It is hard to find which strain is the most studied, although there are several studies relating to HIV.
