Erythema infectiosum

Erythema infectiosum is mainly caused by human parvovirus B19 infection, which will cause some red and swollen erythema on the skin, accompanied by symptoms such as fever and itching.

Erythema infectiosum is a viral skin disease, mainly caused by human parvovirus B19 infection. After infection, butterfly-shaped and edematous erythema often appears on the cheeks, and there may also be local itching and burning sensations. It is generally more common in spring and autumn, and some are accompanied by systemic symptoms, such as fever, sore throat, and conjunctival congestion. Adult patients may also experience migratory arthritis. Erythema infectiosum requires symptomatic treatment based on symptoms. If the local itching symptoms are severe, calamine lotion can be applied topically to relieve the itching symptoms. Oral antihistamines can be taken when necessary, such as cetirizine hydrochloride, chlorpheniramine and other drugs. If arthritis occurs simultaneously, oral non-steroidal anti-inflammatory drugs such as indomethacin, celecoxib and other drugs need to be taken under the guidance of a doctor to relieve local symptoms.

During the treatment, you should eat light and easily digestible food, drink more warm water, get more rest, and isolate yourself to avoid infecting others. Do not scratch your skin when it itches, so as to avoid symptoms of infection and inflammation on the skin.
