Well, if you are looking for a genetic disease, Huntington's disease is the one that manisfests later in life (when a person is in his/her 30s, 40s or later). But, however, it is an autosomal dominant disroder, so your story character has to have family history of this disease (or be adopted).

It's not fatal but there's no cure.  It can be managed effectively with drugs, nutritional supplements, surgery or a combination of these.  The treatment depends on the location and severity, any complications and a person's response to previous treatment.  There can be for some long remissions, sometimes years, when there are no symptoms.  Unfortunately, the disease usually recurs at various time throughout a person's lifetime.  Predicting when either a remission or a relapse will occur just isn't possible.

Yes. This happens especially with Hepatitis B and Hepatitis C, the chronic forms of which may develop many years after the actual infection. Till then, these viruses lie dormant in the body and the person may have no symptoms whatsoever. Also, the person may not have any symptoms when he/she got infected with the virus first (ie, the acute phase may go unnoticed and later the chronic form may manifest). Infact, the acute form of Hepatitis C is totally asymptomatic.

Go to www.webmd.com.  Go to check your symptoms, then follow their advise.  Don't delay.  It could be serious, and it could worsen.

probablly a few days before the symptoms appear and a couple of weeks after.

I think that meningitis, both viral which is the non lethal one and bacterial which is deadly, have these symptoms.

This is caused by a virus that is very common among children younger than 5.  The degrees of infection vary but can include fever, blisters in the mouth, on the palms of the hands and soles of the feet.  It takes 5 to 7 days to run its course.

I had West Nile (Meningitis) last August.  Symptoms lasted through November.  There are 3 phases, West Nile Virus Fever (mild flu-like symptoms), West Nile Meningitis which affects the external brain membranes and West Nile Encephalitis which is the most deadly form.  There is great debate as to whether or not a person becomes immune from becoming symptomatic once they've had the virus.  The reason is that the virus has not been in this country long enough to do true studies. There is a wonderful site to go to with other West Nile Survivors ... we all listen to each other and answer questions about our own experiences with this virus:http://p102.ezboard.com/bwestnilevirussurvivorsfoundation

Sounds like a virus.  If it has been going on for a long time, it could be a serious condition.  You need to see a doctor.

This normally happens when you have a fever or you have general malaise.  sometimes you are not aware that your body is reacting to something bad.   This is normally related to diseases like malaria. See a doctor if symptoms persist.
