Answer

CMV infection is thought to be specific to humans. The age at presentation, clinical manifestations, and route of infection may vary from person to person, but very few people escape infection during their lifetime.

International

Serologic surveys conducted worldwide demonstrate CMV to be a ubiquitous infection of humans. Depending on the population surveyed, CMV may be found in 40%-100% of people, depending on socioeconomic conditions. Infection earlier in life is typical in developing countries, whereas up to 50% of young adults are seronegative in many developed nations.
