As long as virus ..: Good morning, CMV can be spread as long as the virus is present in the body fluids or body surface, the presence being detected by pcr test. Igm informs recent exposure; igg shows past exposure. Presence of rash indirectly suggests an active clinical evidence. Presence of an igg and absence of igm antibodies suggests a non contagious state.
