West Nile
Virus

Mosquito bites cause West Nile virus if the
mosquito is infected with it.

Signs & Symptoms

Most people who get the virus will have no symptoms. About 1 in 5 persons
will get mild ones (West Nile fever). Symptoms usually occur 3 to 14 days
after being bitten by an infected mosquito. See Doctor for the
following:

Fever; headache; body aches
Skin rash on the trunk of the body
(sometimes)
Swollen lymph glands (sometimes)

About 1 in 150 persons get symptoms of a severe infection (West Nile
encephalitis or meningitis). Get Immediate Care for the following:

High fever; stiff neck; severe headache;
muscle weakness
Tremors; confusion; convulsions;
Decreasing level of consciousness;
paralysis

Prevention

Protect yourself from mosquito bites. Stay indoors at peak mosquito
biting times (dawn, dusk, and early evening). Apply an insect repellent with
DEET to clothing and exposed skin to last long enough for  the times you
will be outdoors. Wear long-sleeved shirts and long pants when you are
outdoors.
