It is a mild illness but during pregnancy can cause serious effects on the fetus. The infection usually occurs in young school-aged children. It has a classic feature that the child develops a high fever and runny nose and as soon as the fever settles a bright red rash appears, mainly on the trunk. It is uncommon on the face and limbs. The rash lasts only about two days.
Treatment is simple.
Give paracetamol for the fever. The rash does not require any special treatment as it tends to fade rapidly. Dr Bill's - Home Page.
