Nile virus (WNV) is a mosquito-borne disease first detected
in the United States in 1999. WNV first appeared in California
in 2003 and by 2004, WNV had spread to all 58 counties.
Risk of infection is reduced through the concerted actions
of local and state public health and vector control agencies.
People can protect themselves by taking precautions to avoid
being bitten by mosquitoes. - CDPH
