How many people with severe West Nile virus infection die?
There is no specific treatment for West Nile virus infection. People who experience mild symptoms usually get better without any medicine after a few days. People with severe illness may be hospitalized and given intravenous (IV) fluids. They may need to be on a machine called a ventilator to help them breathe. Their doctor also will try to keep them from getting other infections, such as pneumonia.
