Should I seek medical care for someone with West Nile virus?

If you see a person developing signs of severe West Nile virus (WNV) illness, such as unusually severe headaches or confusion, seek medical attention immediately. Also encourage pregnant women and nursing mothers to talk to their doctors if they develop signs that could indicate WNV.

There is no specific treatment for WNV infection or a vaccine to prevent it. In more severe cases, people usually need to go to the hospital, where they will receive intravenous fluids, assistance with breathing, and nursing care.
