A rise in dengue fever cases has prompted Florida officials to issue another health alert for the mosquito-borne illness — which has so far infected at least 10 people across the state. Two cases of locally contracted dengue have been discovered in Broward County this year, according to the department’s latest surveillance report. The mosquito-transmitted virus is also known as “breakbone fever” for the fever, muscle aches, and joint pains associated with it. Americans have traditionally contracted dengue from traveling overseas to locations where it is widespread — making the new cases spread locally unusual. In total, Florida has reported nearly 200 cases of dengue among people who traveled to such areas.
