Ganciclovir
Ganciclovir has also been used with some success in treating "Human herpesvirus 6" infections.
Roseola
Roseola 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 fever generally lasts for three to five days. The rash is generally pink and lasts for less than three days. Complications may include febrile seizures, with serious complications being rare.
It is caused by either "human herpesvirus 6" (HHV-6) or "human herpesvirus 7" (HHV-7). Spread is usually through the saliva of those who are otherwise healthy. However, it may also spread from the mother to baby during pregnancy. Diagnosis is typically based on symptoms but can be confirmed with blood tests. Low numbers of white blood cells may also be present.
Treatment includes sufficient fluids and medications to treat the fever. Nearly all people are infected at some point in time. Males and females are affected equally often. The disease was first described in 1910 while the causal virus was determined in 1988. The disease may reactivate in those with a weakened immune system and may result in significant health problems.
