August 15, 2003 Healthwatch: West Nile Virus - are you at risk?
by Erica Bamgbopa Bureau of Medicine and Surgery Public Affairs
WASHINGTON (NNS) -- You are standing in the backyard, eating barbeque chicken, chatting with friends and family, having a good time. Meanwhile, a female Culex pipiens mosquito is looking for her next meal - blood. She needs the protein to produce several hundred eggs. She bites; you scratch your arm. A few days later, you have a fever, headache and body-aches; typical symptoms of the flu. You visit your doctor and the diagnosis is a mild form of West Nile Virus. Your doctor treats the symptoms, and a few days later, you feel as good as new.
Until preventative measures like vaccines are discovered, surveillance and common sense are the best course of action to avoid infective mosquito bites. "We try to make everyone aware of the disease and where it exists," said Lt. Cmdr. Gary Tetreault, medical entomologist at the Naval Environmental Health Center, Portsmouth, Va.
Most people bitten by an infected mosquito never experience symptoms, according to the Center for Disease Control and Prevention (CDC). Twenty percent of those who do experience flu-like symptoms. In rare, severe cases, the disease can be life threatening with symptoms including high fever, stiff neck, disorientation, coma, tremors, convulsions, muscle weakness and paralysis. People over 50, and adults and children with weak immune systems are most at risk.
By following some general guidelines, you can reduce the risk of being infected. Consider staying indoors at dusk and dawn, when mosquitoes are most active. If that isn't possible, wear long sleeves and pants when outdoors, and use bug repellent containing 5-24 percent DEET. Also, drain standing water, such as birdbaths and wading pools, because this prevents mosquitoes from laying their eggs.
In 1999, when the virus first appeared in the United States, there were 62 cases and seven deaths, according to CDC. In 2002, more than 4,100 people were infected and 284 died.
