Erythema Infectiosum

(Fifth disease, parvovirus B19 infection)

Erythema infectiosum is an acute disease caused by parvovirus B19 and caused slight constitutional symptoms and a blotchy or maculopapular rash that begins on the cheeks and then travels through the exposed extremities. The diagnosis is made clinically; treatment is not usually necessary.

The disease is caused by the human parvovirus B19. It is normally in the spring before, an area-wise occurrence in children (especially 5-7 years) every few years usual. The spread by droplet infection and probably takes place by percutaneous exposure to blood or blood products, with a large number of secondary infections among the family In listening; the infection can occur with or without symptoms and findings.

Pathophysiology parvovirus B19 causes a transient suppression of erythropoiesis, which runs mild and asymptomatic, except in children with hemoglobinopathies (eg. As sickle cell anemia) or other disorders of red blood cells (eg. As hereditary spherocytosis), which can develop a transient aplastic crisis , Immunocompromised patients may develop a prolonged viremia (10-12 days), leading to severe anemia (chronic pure red cell aplasia). erythema infectiosum can be transmitted transplacentally and sometimes lead to a stillbirth or severe fetal anemia with extensive edema (hydrops). However, half of the pregnant woman is immune because of previous infection. The risk of fetal death is 2-6% after maternal infection, with the greatest risk in the first half of pregnancy. Symptoms and signs The incubation period is 4-14 days. The typical symptoms are initially non-specific, flu-like symptoms (eg. As low temperatures, light ailing). A few days later, indurated, confluent erythema on the cheeks and a symmetrical redness on arms, legs appear (often on the extensor surfaces) and trunk, which usually spares the palms and soles. The rash is maculopapular, tends to confluence and formed reticular or lacy pattern slightly raised areas, or blotted with exanthemfreier center, which are most pronounced at the exposed places. The rash as the entire disease usually takes 5-10 days. However, the rash can last for weeks and exacerbate under sunlight, sports, heat, fever and emotional stress.
