Bill Gate's genetically modified frankenstien mosquito unleashed on Florida

"Genetically modified mosquitoes have been released for the first time in the United States as part of an experiment to combat insect-borne diseases such as Dengue fever, yellow fever, and the Zika virus."

"UK-based biotechnology firm Oxitec, which is funded by the Bill and Melinda Gates Foundation, said it released the mosquitoes in six locations in Monroe County’s Florida Keys: two on Cudjoe Key, one on Ramrod Key, and three on Vaca Key." -- Epoch Times (07 May 2020)

Only, these diseases are extremely rare or non-existent in the United States. So what exactly is going on here?
