Californian authorities are facing an increase in locally acquired cases of dengue, a dangerous virus spread by Aedes mosquitoes. The Aedes mosquitoes are now present in at least 24 California counties, bringing the threat of not only dengue but also other tropical diseases like chikungunya, Zika, and yellow fever. Authorities are implementing surveillance, response plans, and mosquito control measures to prevent further spread. Mistrust of public health authorities can make outreach challenging, but efforts are being made to educate residents about prevention. With the mosquito threat expected to persist, public participation in prevention efforts is crucial.
