Medically reviewed on May 14, Fifth disease, also known as erythema infectiosum, is a common viral infection among school-aged children. It is caused by parvovirus B19, which spreads through direct contact with fluids or mucus from the nose or mouth of an infected person. Fifth disease causes a bright red “slapped cheek” rash that doesn’t appear until an infected person is no longer contagious.
Fifth disease usually is a mild illness, and some people who are infected may never realize they have it.
Outbreaks of fifth disease typically occur in late winter and early spring. Parvovirus B19 infects humans only and is not the same as the parvovirus that infects dogs. Sometimes, fifth disease does not cause any symptoms. When symptoms occur, they may include mild cold symptoms stuffy nose, runny nose, slight feverbody aches, diswase and fatigue.
These symptoms pass after three or fifht days and are followed primarily in children by a rash that is bright red and usually begins on the cheeks the “slapped cheek” rash. This facial rash is eryhema by a lacy, flat rash that appears on idsease arms, legs, trunk and buttocks. The blotchy rash may itch, and it may last from several days to several weeks before it fades.
Even after the rash clears, it sometimes may reappear if the skin is irritated by rubbing, heat, cold, exercise or exposure to sunlight. Adolescents and adults with fifth disease may not have any symptoms or they may develop the typical rash, joint pain and swelling most often at the knuckles, wrists and knees or both.

The virus itself, or its viral DNA genetic mapalso can be detected in the blood of some patients.
Fifth disease usually goes away within three weeks, but the rash may last longer. Although joint pains in adolescents may last for a few weeks or months, there are typically no long-term joint problems. Fifth disease is spread in the droplets of coughs and sneezes, on dirty tissues, and on drinking glasses and eating utensils. It is difficult to avoid exposure to the illness, because fifth disease is most contagious three to 14 days before its characteristic rash appears.
