A mosquito pool (batch of mosquitoes) sampled on June 13 in Highland Park, has tested positive for West Nile virus. The mosquito pool is the first confirmed indicator of West Nile presence in Lake County in 2019.
“In 2018, there were eight human cases of West Nile virus, including one death confirmed in Lake County,” said Mark Pfister, executive director for the Lake County Health Department and Community Health Center. “Residents need to take action, practicing the 4 Ds of Defense to protect themselves from mosquito bites.”
