Ask a question


Erythema infectiosum is a pathology that affects children (generally between three and fifteen years of age) and is caused by the parvovirus B19. This illness, though benign, is very contagious. Contamination is airborne and the disease is triggered one to two weeks later. Erythema infectiosum is characterized by a cutaneous eruption marked by a bright redness of the cheeks, while the lips are pale. The symptoms first affect the thorax, then the base of the limbs, and are sometimes accompanied by itching and joint pain. Erythema infectiosum disappears by itself after approximately one week.
