Darien health officials say mosquitoes trapped in Darien have tested positive for the West Nile virus.

It was the second positive test in the state so far this year. The virus was found in New Haven earlier last week. There have been no reports of any human cases of WNV.

The Connecticut Agricultural Experiment Station does testing on mosquitoes from all over the state.

The Darien Health Department says finding mosquitoes positive for WNV commonly occurs at this time annually in towns across the state.

More information is available on the Connecticut Department of Public Health’s website.
