Roseola is an acute viral pediatric infection caused by a particular virus. It manifests itself in a three-day fever without any other symptoms, and after the temperature is normalized, a rash similar to rubella.

Roseola or sudden rash is caused by the herpes virus of the sixth type, affecting children from six months to 3-4 years. Most often, children are ill for about a year.
In children older than five years, roseola almost never occurs. Previously, she was often mistaken for rubella, and therefore there was no complete vaccination of children for rubella.
Roseola is often not diagnosed as a disease, it is mistaken for other childhood infections, but more often it is regarded as an allergic rash on medications.

Rashes keep no more than two days, disappearing without a trace, rarely can peeling remain. Rarely there is only fever without a rash with viral changes in the blood picture. With manifestations of fever and rash, children can be drowsy, capricious, eat worse.
An accurate diagnosis is rarely made, since the disease, although not uncommon, is usually not set.
Differential diagnosis is performed with rubella and allergies , because the rash is very similar in appearance, and for three days of a febrile period, children usually get a lot of medication, which could provoke an allergy. In addition, when taking antiallergic drugs rash “passes”. What is considered additional evidence, although it would have passed in any case.
Distinctive features of roseola from all other diseases:
- a rash occurs after three days of fever, just against the background of a drop in temperature,
- rash does not itch
- rash does not happen on the face.
Blood tests for rozeole do not provide information on the exact cause of the disease, it is possible to identify only viral lesions using them. lymphocytosis no shift formula.
