West Nile Virus Human Case

Fairfax County Reports Virginia's First Probable Fatal Human Case of West Nile Virus in 2004

September 27, 2004

The Fairfax County Health Department today announced its first probable human case of West Nile virus (WNV) in 2004. If confirmed, this would be the first reported fatality due to WNV in the Commonwealth of Virginia this year. Laboratory samples are being sent to the Centers for Disease Control and Prevention for confirmation. Final results may take several weeks.

The patient, an elderly male from the Mount Vernon district of the county, developed symptoms mid-September. Subsequently he developed the more serious form of the disease which contributed to his death.

Last year, Fairfax County reported three human cases of the virus, none of which were fatal.

Humans contract West Nile virus most often from the bite of an infected mosquito; but most people bitten by infected mosquitoes do not get sick. Those who do get sick from West Nile virus usually suffer a mild flu-like illness and recover without treatment. In few people, most often older than 50, West Nile virus can cause serious illness such as encephalitis or meningitis. Only supportive treatment is available for more serious cases.

Wild birds also can become infected with West Nile virus. This season one bird has tested positive for West Nile virus in Fairfax County, bringing the statewide West Nile virus-positive bird count up to six as of Aug. 2.

"This is the fifth human case in Virginia. Although we have had a relatively quiet season, West Nile virus is still of concern in Fairfax County and mosquito breeding areas around homes should be eliminated," said Gloria Addo-Ayensu, M.D., M.P.H., health director of Fairfax County. "In addition, residents can protect themselves against mosquito bites using a mosquito repellent containing DEET."

The Health Department recommends the following tips to reduce exposure to mosquitoes:

-Use insect repellent products with up to 30 percent DEET (except on infants age 2 months and younger). Follow label instructions when using insect repellents.

-Wear long, loose and light-colored clothing outdoors.

-Turn over or remove containers in your yard such as old tires, potted plant trays, buckets and toys where water collects.

-Eliminate standing water on tarps or flat roofs.

-Clean out birdbaths and wading pools once a week.

-Clean roof gutters and downspout screens regularly.

The Fairfax County Health Department conducts activities to control mosquito populations in the county and throughout the year has been conducting an aggressive public education, outreach and information campaign called "Fight the Bite."
