Fifth disease is a very common childhood illness. Adults can get it too. It is sometimes called slapped-cheek disease because of the rash that some people get on the face. You spread the disease by coughing and sneezing.
Fifth disease is usually a mild illness that lasts a few weeks. It can be more serious for people with weak immune systems or blood disorders, such as sickle cell disease. It can also cause problems for a developing fetus if exposure to the illness occurs during pregnancy. But this isn't common.
Symptoms usually appear about 2 weeks after exposure to the virus. Early symptoms are similar to the flu—runny nose, sore throat, headache—and may be so mild that you don't notice them.
The rash comes several days later, first on the face and later over the rest of the body. It may be itchy. The rash may last for 7 to 10 days. The rash may come and go for several weeks. This doesn't mean the disease is worse.
Some people also get pain in their joints. This can last for several weeks or even months.
Not all people with fifth disease get a rash or feel sick.
Your doctor can diagnose fifth disease by doing a physical exam and asking questions about your medical history. The disease is easier to diagnose if you have the rash.
Tests aren't usually needed, but they may be done in some cases to confirm that you have fifth disease.
