INVASIVE MOSQUITO SPECIES

In recent years, invasive species of mosquitoes have posed new and difficult threats to public health in California. Although they have not yet been detected in Placer County, Aedes aegypti and Aedes albopictus have been found in a rapidly growing number of California cities and localities, and are likely to spread throughout other areas of California.

Aedes aegypti and Aedes albopictus are important vectors of dengue, chikunguya, and Zika viruses which can cause severe disease and even death in humans. While these viruses have not been transmitted locally in California, hundreds of people return from trips abroad and bring these viral infections back to California which increases the risk of local transmission.
