leaky watering equipment, clogged rain gutter, and anything that will

to use mosquito fish as a preventative measure against mosquito
breeding. The use of mosquito fish is a natural way of
controlling mosquito larvae without the use of insecticides or

Cityís prevention plan.

Exposure to West Nile Virus
Fewer than one out of
150 people who are bitten by an infected mosquito get severely ill,
according to the Centers for Disease Control and Prevention. In
most cases people who are infected never become sick or have only very
mild symptoms for a few days. The virus can in rare cases cause
encephalitis and death. The elderly are most at risk for severe cases
of the disease. There is no specific treatment for the West Nile
virus. In a serious case, an individual may be hospitalized to
ensure good supportive care.
Most people who are
infected with WNV have no symptoms. Of those that become ill,
symptoms include fever, headache, nausea, body aches and mild skin
rash. In a few cases, the disease will progress to encephalitis.
Animals and West Nile Virus
Although the vast
majority of WNV infections in animals have been identified in birds,
WNV has been shown to infect horses, cats, bats, chipmunks, skunks,
squirrels and domestic rabbits. An equine WNV vaccine recently
became available for horses.
The public is encouraged
to report if a recently dead bird (dead less than 24 hours) is found;
contact 1-877-WNV-BIRD. More information is available on the DHS
