The first signs of the West Nile virus activity in Spencer County have been found by Indiana State health officials. The Indiana State Department of Health had mosquitoes test positive for West Nile virus in Spencer County. There is still plenty of mosquito season ahead of us and the risk of human disease remains until after the first hard freeze. Please remain diligent and reinforce prevention and protection methods until that time.
Once West Nile virus is detected in mosquitoes, people are at a greater risk for infection. Fortunately, there are several simple, effective steps Spencer County residents can take to protect themselves from mosquito bites.
• Avoid being outdoors during prime mosquito biting times, dusk to dawn, when possible;
• Apply insect repellent containing DEET, picaradin, or oil of lemon eucalyptus to clothes and exposed skin;
• Install or repair screens on windows and doors to keep mosquitoes out of the home; and,
• When possible, wear long-sleeved shirts and pants when outside.
West Nile virus usually causes a mild form of the illness, which can include fever, headache, body aches, swollen lymph glands, or a rash. However, a small number of individuals can develop a more severe form of the disease with encephalitis or meningitis and other neurological syndromes, including flaccid muscle paralysis. Some individuals may die from the infection. Health officials say that although individuals over age 50 are at greatest risk for serious illness and even death from West Nile virus, people of all ages have been infected with the virus and have had severe disease. There is no vaccine and no cure for West Nile virus. Individuals who think they may have West Nile virus should see their healthcare provider.
West Nile virus is transmitted to humans by mosquitoes that have first bitten an infected bird. A person bitten by an infected mosquito may show symptoms 3 to 15 days after the bite.
The Spencer County Health Department is also asking residents to take steps to rid their properties of potential mosquito breeding grounds by:
• Discard old tires, tin cans, plastic containers, ceramic pots or other containers that can hold water;
• 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;
• Flush ornamental fountains and birdbaths periodically; and,
• Aerate ornamental pools, or stock them with predatory fish.
