The LaSalle County Health Department received confirmation on Friday that mosquitoes from Peru tested positive for West Nile virus. 

The mosquitoes were collected on July 18th and this is the first documented West Nile virus activity in LaSalle County this year.

According to Chris Pozzi, Director of Environmental Health, it is important that people be conscientious about self-protection whenever they are outside during the evening hours. 

In hot, dry weather, mosquitoes that carry West Nile virus breed in stagnant water and multiply rapidly. 

The best way to protect yourself against illness is to wear insect repellent and to get rid of any stagnant water around your home to reduce the number of mosquitoes.
