As the global dengue virus outbreak continues in about 80 countries with over 4.5 million dengue cases and over 4,000 dengue-related deaths, new data from Florida indicates there may be fewer cases this year.

Florida Health's Mosquito-Borne Disease Surveillance Report #46 confirmed 458 travel-associated dengue cases and 142 locally acquired dengue cases in 2023.

As of November 18, 2023, most of the travel-related dengue cases have been associated with visitors from Cuba (272).

And Miami-Dade Country has confirmed the most local dengue cases (133).

In 2022, Florida reported 903 travel-associated and 68 locally-acquired dengue cases.

From a prevention perspective, the U.S. FDA-approved Dengvaxia® vaccine is available but is seldom administered because of required diagnostic testing.

Dengvaxia (CYD-TDV) is a live attenuated tetravalent chimeric vaccine made using recombinant DNA technology.

Recently, the FDA extended Dengvaxia's approval to include children aged 9–16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic.

However, the vaccine is not approved for use in U.S. travelers who are visiting but not living in an area where dengue is common.

Endemic areas can include some U.S. territories and freely associated states.

A new dengue vaccine, QDENGA®, has recently been approved in various countries, without a pre-administration test requirement.

QDENGA (TAK-003) prevents dengue fever and/or severe dengue caused by any of the four serotypes.
