The Florida Department of Health in Miami-Dade County (DOH-Miami-Dade) recently announced the second local case of dengue infection in 2022.

As of July 29, 2022, the greater Miami, Florida area remains under a mosquito-borne illness advisory.

The Florida Department of Health continues conducting statewide surveillance for mosquito-borne illnesses.

Florida's southern neighbor Puerto Rico has reported over 100 local dengue cases this year.

Dengue is a virus spread to humans by Aedes mosquitoes which can also spread chikungunya and Zika viruses.

Most people infected with dengue have mild or no symptoms. Those that do develop symptoms typically recover after about one week.

Severe dengue can occur, resulting in shock, internal bleeding, and death.

While there is a U.S. FDA-approved dengue vaccine known as Dengvaxia, it has limited availability in the USA.

Before administering Dengvaxia, diagnostic testing is encouraged by the U.S. CDC.

As of July 20, 2022, the World Health Organization and the FDA recommend dengue vaccines should be given to persons with confirmed prior dengue virus infection.

This is because preexisting cross-reactive antibodies have been implicated in the protection and pathogenesis of subsequent infections with 1 of the four dengue virus serotypes.
