Human Herpes Virus 6, also called "exanthem subitum," "sixth disease," and "roseola," is a common disease that usually affects infants. Caused by one of the eight herpes strains that can infect humans, roseola infects most children by the time they reach kindergarten age, according MayoClinic.com. The disease is acute, meaning that it comes on suddenly, but is not chronic.
Fever
The symptoms of roseola are generally mild, though some children will experience the full range of symptoms, including fever. When it occurs, the fever generally comes on quickly and lasts for three to five days. The fever caused by roseola is often high, with temperatures of 103 to 105 degrees Fahrenheit not uncommon. It generally responds well to over-the-counter medications, such as acetaminophen, according to Medline Plus. Cool sponge baths may increase comfort and help to control the fever. Because the fever can spike, febrile seizures or convulsions may occur. MayoClinic.com recommends consulting a physician if the child's fever reaches 103 degrees Fahrenheit.
Rash
Like most of the herpes viruses that infect humans, roseola can cause a skin rash. When it occurs, it typically begins on the chest, back and/or abdomen, usually as the fever subsides. The rash often appears as small, flat patches of pink skin, which may be surrounded by a white ring. Though not itchy, the rash can last from hours to several days and may spread to the neck and arms
Other Symptoms
A roseola infection may include other symptoms. These include sore throat, runny nose and red, irritated eyes. Further, a child with roseola may show signs of irritability, as well as swollen lymph nodes in the neck or back of the scalp. Fatigue, loss of appetite and diarrhea may occur. Medline Plus indicates the child should be taken to the emergency room if convulsions occur.
