Columbus Public Health is investigating the year's first case of West Nile virus in a human -- local 61-year-old man, who was not hospitalized and has recovered.

The case is from in an area of the city that recently was treated twice for adult mosquitoes, according to an Aug. 31 news release from Columbus Public Health.

The specific area, near Morse Road and Cleveland Avenue, will be treated again, the release said.

Members of the vector-control staff also have conducted an assessment of the area and provided educational materials, the release said.

Mosquito pools have tested positive for the virus, according to Kelli Newman Myers, CPH spokeswoman.

Residents also can help protect themselves by using insect repellant with DEET, wearing protective clothing at dawn or dusk, repairing window screens and getting rid of any standing water, such as bird baths, rain barrels, flower pots and baby pools, officials said in the news release.

Only about 20 percent of those who re infected with the West Nile virus will become sick, the release said.
