Cytomegalovirus - CMV

Cytomegalovirus (CMV) is a common infection. In the U.S., nearly one in three children is infected by 5 years of age, and over 50% of adults have been infected by age 40.  CMV can be transmitted in several ways: congenitally, by blood transfusion or organ transplantation, and through direct contact with urine or saliva.  The virus is generally asymptomatic in immunocompetent children and adults but can lead to serious complications in immunocompromised individuals or those receiving transplants, neonates, and pregnant women.  Polymerase chain reaction (PCR) testing is commonly used to detect and quantify viral load.  Serology is most useful in immunocompetent individuals, pregnant women with possible active infection, and during pretransplant analysis.
