Fifth Disease

Another common childhood illness that causes a rash is erythema infectiosum, also known as "fifth disease" or "slapped-face fever." The main symptom is a red rash on the face that looks like slapped cheeks and a lacy, pink rash on the backs of the arms and legs, torso, and buttocks. There may be a low fever. The rash may come and go for several weeks in response to changes in temperature and sunlight.

A child with fifth disease is most contagious the week before the rash appears. Once the rash has developed, the child is no longer contagious.

Home Treatment for fifth disease is simply to keep the child comfortable and watch for signs that a more serious illness is present (fever over 38.3°C or 101°F; child seems very sick).

Fifth disease is harmless in children, but it poses a slight risk to developing fetuses. Pregnant women should avoid exposure if possible. If you are pregnant and are exposed to a child with fifth disease, or if you develop a fifth disease-like rash, contact your obstetrician.
