Facts about CMV/HSV/Syphilis Young children are a common source of CMV. By the age of 5 years, 1 in 3 children has been infected with CMV but usually does not have symptoms. A positive test for CMV IgG indicates that a person was infected with CMV at some time during their life but does not indicate when a person was infected.
