Today Ripley County health officials confirmed that a mosquito trapped in the county has tested positive for West Nile virus. The county and the Indiana Department of Health run routine mosquito trapping and testing this time of year, and while there are no confirmed human cases in Ripley County right now, this positive mosquito is a reminder: the risk is real and it’s time to sharpen up the usual summertime precautions.

A little background so we all know what we’re dealing with: West Nile first showed up in the United States in 1999 and was first identified in Indiana in the late summer of 2001. Since then it’s become a seasonal, expected part of mosquito-borne disease monitoring in our state — some years are quiet, other years there’s more activity. The state and CDC track this closely through surveillance systems and dashboards you can check for updates. Indiana GovernmentCDC
How the virus spreads (the short version): infected birds pass the virus to mosquitoes (primarily Culex species), and those mosquitoes can then bite people or animals. People are what experts call “dead-end” hosts — we don’t pass the virus back to mosquitoes — but the bite from an infected mosquito is how most people become infected. That’s why local mosquito surveillance matters: finding infected mosquitoes means the virus is circulating nearby. CDC
What it looks like if someone gets infected: most folks don’t have any symptoms at all. About one in five people who do get sick will have a flu-like illness (fever, headache, body aches, sometimes a rash), and a very small fraction develop the more serious neuroinvasive disease (meningitis, encephalitis) which is more likely and more severe in people over fifty or those with weakened immune systems. Bottom line — most bites won’t turn into a serious illness, but anyone with high fever, confusion, trouble walking, or other severe symptoms should seek medical attention right away. CDC
So what should you do around here this summer? Practical, simple stuff that actually helps:
• Eliminate standing water around your property — bird baths, old tires, buckets, clogged gutters, plant saucers — mosquitoes only need a tiny bit of water to breed. Empty or clean containers at least once a week. Indiana Government
• Use an EPA-registered insect repellent when you’re outside (DEET, Picaridin, IR3535, oil of lemon eucalyptus and others are effective). Follow the label — especially for kids. CDC
• Dress to limit bites during dawn and dusk (long sleeves, long pants, tuck pant legs into socks if you’re spending time in tall grass or brush). Indiana Government
• Repair window and door screens so mosquitoes can’t get inside, and consider mosquito netting if you sleep outdoors. Indiana Government
• If you keep horses, check vaccination status with your vet — equine vaccination against West Nile is widely recommended and works to protect animals that are also at risk. AAEP
A couple of practical local notes: the Ripley County Health Department and IDOH do the trapping and testing on a schedule, and the state dashboard is updated regularly (the IDOH mosquito-borne activity dashboard is refreshed on Tuesdays and Fridays). If you want to follow local activity, those are the places to watch for the most accurate, timely info. WRBI Radio Indiana Government
I don’t want to overstate the danger — one positive trap doesn’t equal an outbreak — but it’s the exact sign we’ve been training our eyes (and traps) to look for. Take the commonsense steps above, check on elderly neighbors and anyone with compromised immune systems, and if you or a family member develops worrying symptoms after lots of mosquito exposure, don’t hesitate to call your healthcare provider and let them know about the bite history.

WRBI will keep an ear on this for you and put updates on the air and WRBIradio.com as the county and state release them. Stay safe, keep your eyes open for standing water, and let’s enjoy the rest of summer without letting the little bloodsuckers get the better of us!
