A second human West Nile virus (WNV) case has been reported in Southern Nevada, health officials note.

The individual, a female under the age of 50, has the more serious neuroinvasive form of the illness and has been hospitalized. The Health District reported its first West Nile case in April in a woman over the age of 50 with the more serious form of the illness; she has since recovered.

There were no reported human cases of West Nile virus in Clark County last year.

“With a second case of West Nile virus, it is important to remind everyone that this is a preventable disease,” said Dr. Joe Iser, Chief Health Officer for the Southern Nevada Health District. “By taking some simple steps, you can protect yourself from mosquito bites at home and when you are traveling this summer. It’s also important to eliminate mosquito breeding around your home to protect yourself and your family.”

West Nile virus is spread through the bite of infected mosquitoes that have acquired the virus by feeding on infected birds. The illness is not spread person to person. Many people with the virus will have no symptoms or very mild symptoms of illness. Mild symptoms include fever, headache, body aches, nausea, vomiting, and sometimes swollen lymph glands or a skin rash on the chest, stomach, and back. In some cases, the virus can cause severe neurologic illness and even death.
