Officials reported a 330% increase in the mosquito population across Orange County this year, with the largest numbers found in Santa Ana neighborhoods.

The mosquitoes are capable of transmitting dengue fever, chikungunya virus, yellow fever and Zika, the district said. Though the viruses aren’t transmitted locally, someone infected abroad who gets bitten in Orange County could be affected.

The mosquitoes were also reported in Anaheim, Buena Park, Costa Mesa, Garden Grove, Huntington Beach, La Habra, Lake Forest, Mission Viejo, Newport Beach, Orange, Westminster, Brea and Irvine.
