Children get many different kinds of rashes-many, though not all, related to infections. Below are
descriptions and photos of rashes associated with fever.
Erythema
infectiosum
Also called fifth disease, this is caused by parvovirus B19.
There is frequently an associated low-grade fever (37.8-38.3 degrees C, or
100-101 degrees F), with a rash appearing seven to ten days later.
The characteristic rash starts as facial erythema-the "slapped cheek"
appearance. This can spread to the trunk and have an erythematous macular
appearance. Central clearing of the rash appears, giving a lacy appearance.
The rash often lasts longest on the extremities, where it has a lacy, reticular
appearance.
People with fifth disease can also develop pain and swelling in their joints
(polyarthropathy syndrome).
Individuals with underlying immune deficiencies who are exposed to this virus
are at risk for developing aplastic anemia.
