how long is roseola contagious
Roseola is contagious. It has an incubation period (from time of exposure to the virus to symptom development) from about five to 14 days. The individual remains contagious until one or two days after the fever subsides. The roseola rash may still be present, but the child or individual is usually not contagious after the fever abates. Roseola is caused by a common virus (belonging to the family of herpesviruses and termed HHV-6).
