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 infects between 60% and 70% of adults in industrialized countries and nearly 100% in emerging countries. An estimated 491 million people aged 15–49 (13%) worldwide have herpes simplex virus type 2 (HSV-2) infection, the leading cause of genital herpes. Reported cases of syphilis (all stages) have increased 74 percent since 2017, totaling more than 176,000 cases in 2021.
