Parvovirus B19 infects only humans. Approximately 60% of adults aged 30 years are immune to parvovirus B19, although few recall having had the infection. Symptoms include a low-grade fever, myalgias, arthralgias, headache, nausea, and rhinorrhea. As the symptoms disappear, children often develop a bright red rash on the cheeks (as if they had been slapped). The infection is contagious in children for a few days before symptoms begin and until the symptoms disappear. When the rash appears, the infection is no longer contagious. The presence of the parvovirus B19 rash is not a reason to keep children home from daycare or school.
