West Nile Statistics: One In 1,000 People Who Get West Nile Virus Die

We spotted this today:

"About four out of five people who become infected by a mosquito bite have no symptoms.
However, about 20% of people who become infected with West Nile virus develop West Nile fever, within two to 15 days afterward.

People over age 50 and the immunocompromised (for example, transplant patients) are at the highest risk for the severe form of the disease.
One in 1,000 people who get West Nile virus die."
