What Are The West Nile Virus Encephalitis Symptoms?
The West Nile Virus is a potentially fatal mosquito-transmitted virus that affects parts of the USA from early summer deep into autumn. The disease was first discovered in Uganda, Africa in women in 1937 and the first diagnosis in the USA was in 1999. Since then, the virus has received a lot of media coverage, due in part to the large spread of areas in which humans can be infected. The West Nile Virus has 3 different forms. In the first stage, which everyone who is infected goes through, no symptoms are felt and the infected human will not even know they are infected. Between a fifth and a quarter of those infected progress to the febrile form of the virus, known as West Nile Fever. The unlucky few – around 1 in 150 – however suffer the severe disease of West Nile encephalitis. The encephalitis symptoms are unpleasant and can lead to death in a small percentage of instances. Encephalitis is a general term for a neuroinvasive condition that results in an acute inflammation of the brain
