State health officials have found mosquitoes infected with West Nile virus in 35 counties including Allen County, where health officials have confirmed 12 positive results of the virus.
There has been one human case of the virus confirmed in Ripley County and one equine case in Adams County, according to the Indiana State Department of Health.
In Allen County, 12 mosquitoes found in eight townships have tested positive for West Nile, said Dave Fiess, director of Vector Control and Environmental Services for the Department of Health.
The department began testing in late June and has tested 181 mosquitoes across the county, Fiess said.
A positive test result prompts an environmental study, he said.
What we have found is that those areas have a lot of standing water in birdbaths, kiddie pools, fountains and buckets, Fiess said.
In addition to getting rid of standing water, wearing protective clothing and mosquito repellant is crucial, even during cooler weather, Fiess said.
Even when it is cooler, the mosquitoes are flying, he said. The temperature has to be below 55 degrees before they stop flying.
Allen County townships that had positive results as of Monday include:
Aboite – 9400 block of Sail Wind Court (1)
Adams – 4800 block of Christofer Lane (2)
Cedar Creek – 10000 block of Black Street (1)
Jackson – 23900 block of East Paulding Road (1)
Maumee – 22500 block of Westmont Court (1)

State health officials have collected and tested nearly 120,000 mosquitoes from all 92 counties for West Nile virus and St. Louis encephalitis, and found no positive evidence of the St. Louis virus.
West Nile virus can cause a mild fever that includes headache, body aches, swollen lymph glands or a rash. Some people can develop a more severe, potentially fatal form with encephalitis or meningitis.
Eight people died in Indiana last year from the virus.
