Prognosis
Children infected with roseola generally have a good prognosis. Most recover without intervention and without long-term effects. Epidemiology
Between the two types of human herpesvirus 6, HHV-6B has been detected much more frequently in hosts. HHV-6B has been shown to affect about 90% of children before the age of 3. Out of these, 20% develop symptoms of roseola, also known as exanthem subitum.Roseola affects girls and boys equally worldwide year-round. Roseola typically affects children between six months and two years of age, with peak prevalence in children between 7 and 13 months old. This correlates with the decrease in maternal antibodies, thus virus protection, that occurs at the age of 6 months. Out of all emergency department visits for children between the ages of 6 months and 12 months who have fever, twenty percent of these are due to HHV-6.Many children who have been exposed and infected can present without symptoms, which makes determining the incidence within the population difficult. History
John Zahorsky MD wrote extensively on this disease in the early 20th century, his first formal presentation was to the St Louis Pediatric society in 1909 where he described 15 young children with the illness. In a JAMA article published on Oct 18, 1913 he noted that "the name Roseola infantilis had an important place in the medical terminology of writers on skin diseases" but that descriptions of the disease by previous writers tended to confuse it with many other diseases that produce febrile rashes.
Tinea faciei is a fungal infection of the skin of the face. It generally appears as a photosensitive painless red rash with small bumps and a raised edge appearing to grow outwards, usually over eyebrows or one side of the face. It may feel wet or have some crusting, and overlying hairs may fall out easily. There may be a mild itch. Treatment
Most infections can be treated with topical antifungal medication. Rarely, more extensive or long-standing infections may require treatment with oral antifungals. The infection will still be contagious between 24 and 48 hours of the first treatment. The ringworm should go away within 4–6 weeks after using effective treatment. See also
