CDC outlines signs and symptoms of West Nile virus

How to know if you have the West Nile virus

It can sometimes be tough to tell that a mosquito has even bitten you until you start scratching at a little bump on your arm or leg.

So how do you know if that mosquito is a carrier of the West Nile virus, and how can you tell if you've contracted the disease?

The Centers for Disease Control has listed some of the signs and symptoms of West Nile fever and West Nile encephalitis, meningitis or poliomyelitis, which is more severe.

West Nile fever has symptoms just like that of the common fever:  headaches, body aches, tiredness. 

The more severe version of West Nile high fever has much stronger symptoms such as disorientation, coma, tremors and paralysis.

The CDC says that 1 in every 150 people who develop the West Nile virus will have the more severe version.  Most people who are infected will not develop any type of illness.

Symptoms of the West Nile fever can usually last for a few days.  The more severe version can last weeks, although neurological effects can be permanent.
