An infectious disease that causes a widespread rash. Also known as slapped cheek disease or erythema infectiosum, fifth disease mainly affects children and is caused by a virus called parvovirus. The rash starts on the cheeks as separate, rose-red, raised spots, which subsequently converge to give the characteristic appearance. Within a few days, the rash spreads in a lacy pattern over the limbs but only sparsely on the trunk. It is often accompanied by mild fever. The rash usually clears after about 10 days. Adults, who contract the disease only rarely, may have joint pain and swelling lasting for up to 2 years. The incubation period is 7 to 14 days, and the only treatment is drugs to reduce the fever.
