Virus Activity and Invasive Species Detection

Virus Activity in the Coachella Valley
The map below is for virus activity in 2018. The District uses mosquito traps (CDC - CO2 baited traps and gravid traps) as part of our surveillance program to detect arbovirus activity. The traps are set up throughout the Coachella Valley in both urban and rural habitats. The map displays within a quarter mile the locations where mosquitoes have tested positive for WNV this year.
