Dec 31, 2023 · During May 2022–April 2023, dengue virus serotype 3 was identified among 601 travel-associated and 61 locally acquired dengue cases in Florida, USA. All 203 sequenced genomes belonged to the same genotype III lineage and revealed potential transmission chains in which most locally acquired cases occurred shortly after introduction, with ...

1 day ago · Dengue goes to Florida. May 29, 2024. In April, the World Health Organization reported a record high of more than 6.5 million cases of people infected with dengue—a 55 percent increase in a single year. Most of those cases were outside of the Untied States. When an outbreak occurred in Florida two years ago, researchers took a closer look.
Dengue Virus 3, Florida, USA, May 2022–April 2023 Florida, particularly in Miami-Dade County. Our analysis suggests that locally acquired cases were driven by large numbers of case-patients with recent travel to Cuba and that DENV persistence in Florida
Maximum-likelihood phylogenetic tree was generated from a subset of 203 complete genomes from Florida (34 local cases, 168 cases in persons with recent travel history to Cuba, and 1 traveler case from Guyana) and 146 complete genomes publicly available (1985–2022) from GenBank representing genotype III, American lineage II.
The bulk of dengue cases in Florida were still related to travel, with most originating from Cuba. Not-so-coincidentally, Cuba experienced a large outbreak of DENV-3 beginning in July 2022.
