This outbreak sired 18 regionally acquired circumstances, together with one which resulted within the younger Miami lady’s demise. To decide the supply of the an infection, docs reviewed the lady’s journey historical past and carried out genetic sequencing of the virus, which confirmed that it was regionally acquired.

Her story is the idea of a letter within the June 10 situation of the New England Journal of Medicine. It ought to function a cautionary story, mentioned co-author Dr. Stephen Morris, an infectious illness specialist at Jackson Memorial Hospital in Miami.

“Florida is a sort of a quasi-endemic area for dengue now,” he mentioned. “We should expect this as a risk moving forward, and doctors in the southern U.S. should know that dengue is on the table as a possible diagnosis.”

Fortunately, most native outbreaks within the United States have been restricted as mosquitoes cannot fly too far, she mentioned.

“We need to be vigilant about fever and illness particularly when we know mosquitoes are active,” Tozan mentioned. Mosquito season spans from spring to fall.

“Climate change is making us see severe weather like unexpected rain and fluctuating temperatures and mosquitoes are very sensitive to this, so all of a sudden we have breeding activity when we normally would not,” defined Tozan, who was not concerned within the new report.

“Be an educated traveler,” she mentioned. “If you are coming back from areas where dengue and other mosquito-borne diseases are prevalent, share your travel history with your doctor.”
