World Mosquito Day, observed on August 20th, 2023, provides a global platform to raise awareness about the impact mosquitoes have on human health and to promote the management of mosquito-borne diseases. In line with these global efforts, California also marks its own Mosquito Awareness Day, as an opportunity to educate Californians about the importance of preventing mosquito breeding sites, protecting themselves from bites, and cooperating with local health authorities to report sightings and potential mosquito-borne disease outbreaks.
Despite reports of recent malaria cases in Florida and Texas, local transmission of malaria in the U.S. is very rare. Most malaria cases are acquired when people travel outside of the U.S. where malaria transmission occurs. Anopheles mosquitoes that can spread malaria are present in California, but the parasites that cause malaria are not currently found in these mosquitoes in California. The last cases of local transmission of malaria in California were reported in 1990.
