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. This day commemorates Sir Ronald Ross's discovery in 1897 that female mosquitoes transmit malaria between humans, a breakthrough that prompted pivotal advances in public health. The day serves as a reminder of the ongoing battle against mosquito-borne diseases such as malaria, dengue, Zika, and chikungunya, and emphasizes the importance of research, prevention strategies, and collaborative efforts in controlling their spread.

In line with these global efforts, California also marks its own Mosquito Awareness Day, underlining the state's dedication to combating these tiny but potent threats. California's day of observance brings attention to the significant role of mosquitoes in transmitting diseases within the state, from West Nile virus to St. Louis Encephalitis. It is 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.
