Erythema infectiosum is a typical childhood viral disease that usually has a good prognosis.
It is caused by a virus called parvovirus B19. The virus is transmitted by contact with secretions (saliva, mucus) from an infected person. The incubation period is 1-2 weeks before symptoms appear.
The most common symptoms are: reddening of both cheeks, reddening/network-like rash of the skin (which takes on a "lace-like" shape) lasting between 1 and 3 weeks, occasionally a rash on the hands and feet in the shape of "gloves" and "socks", fever, headache, mucus and, rarely, more serious symptoms such as anaemia, haemorrhage and decreased white blood cells.
The diagnosis is usually made clinically, by interview and physical examination.
Symptoms need to be treated with painkillers and/or aimed at managing the symptoms. The prognosis for this infection is usually good. Children with erythema infectiosum should be kept away from close contact with pregnant women.
