Dayna Bennett contracted the West Nile Virus back in August of 2003 and was hospitalized with viral meningitis. Today, she has very little memory of being ill. She says: “I basically slept for three months. Today, I am still having issues with it. When the weather is very hot, I feel like I have it again. I don’t get as sick as I did in 2003, but I have fatigue and flu-like symptoms. I contacted the CDC in 2004 to find out if there was anything I could do, if West Nile is like other mosquito-borne diseases. I was told no and that it was “all in my head.” Recently, I have read research that West Nile is like other diseases, in that it stays in your system and you have flare ups. I also talked to a neurologist recently who told me that my temporal lobes are damaged because of West Nile. I have memory loss that interferes with my everyday life. I think it’s important that more research be done on this serious illness.”
Dayna Bennett was infected with the disease the last time it terrorized the U.S. in epic proportions. And from the likes of her testimony it’s quite clear we’re dealing with a pretty potent virus.
The CDC reports that West Nile virus season is off to an early start this year, which doesn’t bode well for what’s to come. Most West Nile virus exposures in the United States occur from July through October, with a peak during the first two weeks of August. Peak season in Texas is under way, and there are already 336 cases of West Nile illnesses, including 14 deaths reported as of August 13, making this the largest outbreak of West Nile virus in Texas since 2003. The virus has been appearing in many parts of the country, but almost half of the cases are in Texas and the numbers are rising.
Bruce Clements, Director of Community Preparedness at the Texas Department of State Health Services, tells CDC that Texas is currently seeing more than three times as many cases than previously seen in Texas since 2003. “Texas is on track to have the worst year ever for West Nile virus infections,” Clements said. “Assuming normal disease progression, we will outpace 2003, our worst year in terms of the number of cases.”
West Nile virus was first isolated in the West Nile sub-region of Uganda in 1937. The virus first appeared in the United States in 1999 in New York City. Today, we know that mosquitoes get the virus from birds they bite and the virus is spread to humans from mosquito bites.
Roughly one in five infected people get sick when infected with the virus. Most people who do get sick from the virus experience flu-like symptoms that generally last a few days; although some people report having the illness last for several weeks or longer like in the case of Dayna Bennett. Others who get the virus and become ill may develop the more severe form of West Nile virus disease, called West Nile Neuroinvasive Disease (WNND). People who develop WNND may experience headaches, high fever, neck stiffness, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. Although rare, about 10% of people with WNND will die. Of the 336 human cases reported in Texas so far, 200 are the more severe cases.
Not every mosquito carries the virus, and about 80% of people who are infected with West Nile virus will not show any symptoms at all. Still, this virus has made a strong comeback, so precautions should be taken. Awareness and personal protection can be a big step toward reducing your chance of getting infected.
The best way to protect yourself from West Nile virus is to avoid getting bitten by mosquitoes. Here are some tips:
– Use insect repellent containing an EPA-registered active ingredient when you’re outdoors and always follow the package directions
– Mosquitoes are most active at dusk and dawn. Be sure to use insect repellent and wear long sleeves and pants at these times or if possible, consider staying indoors during these hours
– Keep mosquitoes out of your home by making sure you have good screens on your windows and doors
– Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace bird baths weekly. Keep children’s wading pools empty and on their sides when they aren’t being used
As of August 13, 2012, Six hundred ninety-three cases of West Nile virus disease in people have been reported to CDC ArboNET from Alabama, Arizona, Arkansas, California, Colorado, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Jersey, New Mexico, New York, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee and Texas
