West Nile found in Marion County mosquitoes

INDIANAPOLIS — Health officials are urging Hoosiers to take extra precautions this year to protect themselves after mosquitoes in two counties have already tested positive for West Nile Virus.

The Indiana State Department of Health says mosquitoes in Elkhart and Clark counties have tested positive for the virus as of July 1. No human cases of West Nile Virus have been detected so far in 2019, however the health department expects increased West Nile activity throughout the state as the season continues.

“Each year, we see people become ill as a result of mosquito bites,” said State Health Commissioner Kris Box, MD, FACOG. “When we find evidence of the virus in multiple counties, that means the risk is starting to increase statewide. It only takes one bite from an infected mosquito to cause a severe illness, so Hoosiers in every county should be taking precautions.”

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.

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;
  • 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;
  • Aerate ornamental pools, or stock them with predatory fish.
