Facts about CMV/HSV/Syphilis 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. CMV testing should be done within 2-3 weeks of birth to determine if it is congenital. 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. Reported cases of syphilis (all stages) have increased 74 percent since 2017, totaling more than 176,000 cases in 2021.
