Roseola, also known as sixth disease, is an infectious disease caused by certain types of virus. Most infections occur before the age of three. Symptoms vary from absent to the classic presentation of a fever of rapid onset followed by a rash.
The acquisition of HHV-6 in infancy is often symptomatic, resulting in childhood fever, diarrhea, and exanthem subitum rash (commonly known as roseola). Although rare, this initial infection can also cause febrile seizures , encephalitis or intractable seizures.

Human herpesvirus 6 (HHV-6) Human herpesvirus 7(HHV-7) Exanthem subitum (meaning sudden rash), also referred to as roseola infantum (or rose rash of infants), sixth disease and (confusingly) baby measles, is a benign disease of children, generally under two years old, whose manifestations are usually limited to a transient rash ("exanthum") that occurs following a fever of about three day's duration. Until recently, its cause was unknown: it is now known to be caused by two human herpesviruses, HHV-6 and HHV-7, also called Roseolovirus. Despite the fact that it is occasionally called baby measles, it is caused by a different virus from measles, which is usually more severe. However there are subtypes of the HHV-6 virus that are the most aggressive viruses known and quickly overcome the immune system. HHV-6 has also been found in MS patients, and is thought to be a co-virus in Chronic Fatigue Syndrome. As well as AIDS victims and one school of thought holds HHV-6 as a co-factor with...
Typically the disease affects a child between six months and three years of age, and begins with a sudden high fever of 102-104 degrees Fahrenheit (39-40 degrees Celsius). This can cause, in some cases, febrile convulsions (also known as febrile seizuresor fever fits) - due to the suddenness of the rise in body temperature, but in many cases the child appears and acts normal. After a few days the fever subsides and just as the child appears to be recovering, a red rash appears. This usually begins on the trunk, spreading to the limbs but usually not affecting the face. It disappears again in a matter of hours to a day or so. In contrast, a child suffering from measles would usually be more unwell, with symptoms of conjunctivitisand a cough, and their rash would affect the face and last for several days.
There is no specific vaccine against or treatment for, exanthem subitum, and most children with the disease are not seriously unwell. The child with fever should be given plenty of fluids to drink, and acetaminophen or ibuprofento reduce the temperature. He or she should also be kept more lightly clothed than normal if he or she is very hot. The rash is not particularly itchy and needs no special lotions or creams. It is likely that many children catch exanthem subitum "subclinically"; in other words, they show no outward sign of the disease. Others may be unwell enough that a doctor's opinion is required to confirm the diagnosis, and particularly to rule out other more serious infections, such as meningitis or measles. In case of febrile seizures, medical advice is essential.

Older infants are at greatest risk of acquiring roseola because they haven't had time yet to develop their own antibodies against many viruses. While in the uterus, babies receive antibodies from their mothers that protect them as newborns from contracting infections, such as roseola. But this immunity decreases with time. The most common age for a child to contract roseola is between 6 and 15 months.
