4. Is Roseola Infantum Contagious?
Roseola is extremely contagious. As with other viral illnesses, such as the common cold, sixth disease spreads through droplets of saliva or other bodily fluids. This makes person-to-person transmission likely between classmates and family members. Contracting the virus may be as simple as sharing a cup with someone who has it.
Roseola is contagious even if a person does not have a rash. In fact, roseola is the most contagious post-infection but pre-fever and during the fever stage. Once the tell-tale rash appears, the affected child is no longer contagious.
