West Nile rapidly heading west -Health officials predict virus may hit California by next yearASSOCIATED PRESS - MSNBC July 29 , 2002 —NOBODY KNOWS
how bad the mosquito-borne illness will get — although a
rapidly growing outbreak among 32 people in Louisiana began a
month earlier than West Nile has ever struck in this country, a
big worry. But it’s clear the virus first detected in New York
City a mere three years ago has become a permanent summertime
threat in most states. They get a
flu-like illness, with fever, headache and muscle pains, that
lasts two or three days.

The virus is spread to humans and animals by the bite of an infected mosquito (primarily Culex pipiens, the common house mosquito). Mosquitoes become infected by feeding on birds that carry the virus. The virus is not spread by person-to-person contact such as touching or kissing. There is no evidence that a person can get the virus from touching infected birds, but people should always wear gloves and exercise caution when handling dead animals. Many people who are infected with West Nile virus experience no symptoms. Others may experience mild symptoms, such as low-grade fever, headache and body aches, skin rash or swollen lymph nodes, within three to 15 days. In some people, particularly the elderly, children or people with weak immune systems, the virus can cause encephalitis (inflammation of the brain tissue), which can result in permanent neurological damage and, in rare cases, death. Encephalitis symptoms include the rapid onset of severe headache, high fever, stiff neck, muscle weakness and coma. Some at-risk
cities spray pesticides to reduce mosquito populations. In
areas where the virus has been found, people should take the
following precautions to avoid exposure to mosquitoes: From April
to October, minimize time spent outdoors at dawn, dusk and
in the early evening, when mosquitoes are most active. Wear
long-sleeved shirts and long pants when outdoors. Apply
insect repellent sparingly to exposed skin and clothing,
according to manufacturer’s directions. Repellent may
irritate the eyes and mouth so avoid applying it to the
hands of children. Make sure
that doors and windows having tight-fitting screens. Remove
water-holding containers from your property, such as
discarded tires, tin cans, ceramic pots and plastic
containers to eliminate standing water, which serves as
breeding grounds for mosquitoes. Change the
water in bird baths at least once a week. Drain water from pool covers and keep pools and hot tubs cleaned and chlorinated.
The Mosquito Control Association also recommends
frequently changing birdbath water, stocking ponds with
mosquito-eating minnows and using larvicides in unavoidable
standing water. In accordance with Title 17 U.S.C. Section 107, any copyrighted work in this message is distributed under fair use without profit or payment for non-profit research and educational purposes only. [Ref. http://www.law.cornell.edu/uscode/17/107.shtml]
