How do people get roseola?

Virus: Roseola is a viral infection that causes a rash and fever. It is common in infants and children. The most common virus is human herpesvirus 6, but other viruses can cause the same clinical picture. Not the same herpes virus that causes painful genital blisters. It is spread from contact with respiratory secretions (ie saliva) of an infected person (usually before symptoms even show it is spread).

What are the tests for roseola?

What are the tests for roseola?

Dx by Hx & exam: I don't recall ever needing or doing a "test" for roseola. It is a minor illness that is common & distinctive in its features. Most will label the process when enough features present, which often takes a few days. In a research setting, blood tests obtained at the time of first fever & 2-4 weeks later will document rise in antibody production to the virus.

Does anyone know anything about treating roseola?

Comfort only: Treatment is directed at assuring proper hydration, nutrition and rest. These kids can be quite unhappy for the 3-7 days f this illness and the fever can be unresponsive to meds. As long as they can make pee every 6-8 hours and take in some nutrients, this will pass.

What is the treatment for roseola?

Control the fever: Roseola is a common viral illness in young children that typically causes very high fever, then a rash. The best treatment is to control the fever with Acetaminophen or Ibuprofen (for children 6 months and older). Encourage plenty of fluids and rest if your child seems tired. The rash is not bothersome and resolves on it's own. In general, the rash does not typically appear until the fever breaks.

I think my daughter has the roseola virus. Am I the one who gave it to her? Will it effect her when she gets older? Is herpes virus 6 dangerous?

I think my daughter has the roseola virus. Am I the one who gave it to her? Will it effect her when she gets older? Is herpes virus 6 dangerous?

Not harmful: Hhv-6 is harmful only to a fetus. She probably caught it at school. Not a serious problem, unless she exposed a pregnant lady. By the time the rash appears, the person has had the virus for a while and had been contagious. No treatment necessary.

Is Roseola dangerous?

Generally not.: It is a viral illness with a fever and a rash, occurring in young children. With fluids and over-the-counter fever reducers such as acetaminophen (Tylenol) or ibuprofen (Motrin/Advil), a child will recover in a couple of days. However, if there are any concerns about the diagnosis or what else to do, please see your child's pediatrician.

Can adults catches roseola?

Can adults catches roseola?

Yes: When saying "catch", you would need to be more specific. As far as being a carrier, yes, they can, unless they had as a child. As far as having symptoms of it, much less likely, as it is common in children and adults have probably had it even if it was not diagnosed as such.

Can a baby get roseola more than once?

Unfortunately yes!: Roseola infantum usually cause by herpes type 6, 7 etc, are viruses! Same as getting cold sores! You can have repeated infections like colds, aside from giving the parents lots of sleepless night because of the high fevers and subsequent rashes...It is fairly a benign virus illness! Regards!
