Aug. 24—GREENSBURG — A mosquito sample collected in Decatur County has tested positive for West Nile Virus, although no human cases of WNV disease have been detected at this time.
The Indiana Department of Health expects WNV activity to continue across the state during mosquito season, which continues through the first hard freeze.
According to Decatur County Health Department Executive Director Sean Durbin, even a container as small as a bottle cap can become a mosquito breeding ground, so residents should take the following steps to eliminate potential breeding grounds:
—Discard old tires, tin cans, ceramic pots, or other containers that can hold water;
—Each week, empty and scrub items that hold water such as birdbaths, toys, pools, and flowerpot saucers;
—Repair failed septic systems;
—Drill holes in the bottom of recycling containers left outdoors;
—Keep grass cut short and shrubbery trimmed;
—Clean clogged roof gutters, particularly if leaves tend to plug up the drains;
—Frequently replace the water in pet bowls;
—Aerate ornamental pools, or stock them with predatory fish.
State health officials recommend the following personal protective measures:
—Avoid being outdoors when mosquitoes are active (especially during evening hours, from dusk to dawn, and in the early morning);
—Apply an EPA-registered insect repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus, or para-menthane-diol to clothes and exposed skin;
—Cover exposed skin by wearing long sleeves and long pants in places where mosquitoes are especially active, such as wooded and shady areas;
—Install or repair screens on windows and doors to keep mosquitoes out of the home.
About 80 percent of people infected with WNV virus will not develop any symptoms.
About 20 percent of people infected with WNV will develop an illness accompanied by fever, headache, body aches, joint pains, vomiting, diarrhea or rash.
Less than 1 percent of people infected with WNV will develop severe illness affecting the nervous system, which can include inflammation in the brain or in the membranes that cover the brain and spinal cord.
About 10 percent of severe WNV disease cases are fatal. People older than 60 years and those receiving immunosuppressive medications or treatments are at greatest risk of severe WNV disease.
People who think they may have West Nile virus should contact their healthcare provider.
