Two mosquitoes in Clay County were recently discovered to be carriers of the West Nile virus.
"People should be concerned, but there is no reason to panic," Clay County Environmental Health Specialist William "Bill" Hale said.
Because of the large amounts of rain in recent months, there is a higher mosquito population.
To help curtail the mosquito population Hale encourages residents to eliminate standing water.
He also urges the public to use common sense to avoid being bitten, such as limiting time out doors, using insect repellent and limiting exposure by wearing clothing that covers the skin.
"With the 4-H Fair going on, people will be out and so will the mosquitoes," he said. "People just need to take precaution."
Throughout the summer months birds and mosquitoes are collected and tested by the Indiana State Department of Health.
"One of the mosquitoes was two miles south of Brazil," he said. "The other was inside city limits."
