The Indiana State Department of Health (ISDH) is asking residents of the Hoosier State to take proper precautions against mosquitos after the West Nile virus was detected in the state.

ISDH said Tuesday that a mosquito sample collected in Vigo County had tested positive for the West Nile virus.

With this new information, many residents like Robert Wilcox, don't know much about the virus or the potential dangers of it.

"I've heard its dangerous if you catch it." said Wilcox. 

Which is why ISDH is doing their part in spreading the word about the virus as it could travel throughout other parts of the state. 

As of now, ISDH says no human cases of West Nile virus have been detected in the state, though more West Nile virus activity is expected throughout the state as the mosquito season progresses.

State health officials recommend the following preventive measures:

  • Avoid being outdoors when mosquitoes are active (especially late afternoon, dusk to dawn, and 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 a hat, long sleeves, and long pants in places where mosquitoes are especially active, such as wooded areas.
  • Install or repair screens on windows and doors to keep mosquitoes out of the home.

With mosquitos able to transmit a variety of diseases, ISDH says Hoosiers should do their part to reduce and remove potential mosquito breeding grounds.

The state health department says that even a small amount of standing water can become a mosquito breeding ground.

ISDH is asking residents to take these steps to avoid potential breeding grounds:

  • Discard old tires, tin cans, 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.

ISDH says that about 80% of people infected with West Nile virus will not develop any symptoms at all, but that about 20% will develop an illness accompanied by fever, headache, body aches, joint pains, vomiting, diarrhea, or rash.

The health department urges anyone who thinks they may have West Nile virus to contact their healthcare providers.

Our Tuesday was nothing short of chilly, gloomy, gray and wintry throughout the Tri-State; afternoon high temperatures only reached as high as the middle to low 30s throughout the region. Our peak temperature of 32° in Evansville was 16° below the norm for this time of the year. As for the evening ahead, cloud cover and cool air will linger - additionally, there have been reports of sporadic flurries on and off throughout the day and some portions in the Lower Ohio Valley may continue to see brief snow showers through 10 o’clock this evening. Our winds will shift southward overnight tonight into early Wednesday morning and while it won’t necessarily drive temperatures higher for the predawn hours, It will help keep temperatures from falling much further than where they currently stand. Extract the morning low temperature near 29° in Evansville as we kick off our midweek.
