7th malaria case confirmed in Sarasota as Florida remains under health advisory

Health officials have confirmed a seventh case of locally-acquired malaria in Sarasota County as Florida remains under a health advisory for the mosquito-borne illness.

The most recent case was confirmed in the second week of July, according to a Florida Department of Health report.

All seven cases have originated from the same area in north Sarasota County that includes the Desoto Acres and Kensington Park neighborhoods, a health department spokesperson said Monday.

An illness alert, which is more severe than an advisory, was issued for Sarasota County and Manatee County in June.

Malaria is often contracted by U.S. citizens traveling abroad, but local transmission of the virus is rare.

The first local case of the virus was first recorded in May, and five more followed in June. Local mosquitoes were also found to be carrying malaria in June.

All of the locally contracted cases were Plasmodium vivax malaria. P. vivax is the most common type of malaria infection in humans. It is less fatal than other types but can still be life-threatening.

Malaria is only transmitted via mosquito bite. Symptoms include headaches, nausea, vomiting, sweating, fever and chills. Anyone experiencing these symptoms should seek medical help within 24 hours of symptoms, health officials say.

Residents are urged to use bug spray, avoid areas with mosquitoes, and wear protective clothing outside.
