RIO, Florida (AP) - Two more cases of dengue fever have been confirmed in central Florida, bringing the total number of patients suffering from the mosquito-borne illness to 20.

All the patients contracted dengue fever in the Rio and Jensen Beach areas.

Health officials tell The Palm Beach Post that there may be little relief from mosquitoes in those areas because wet weather is expected to continue into next week. Mosquitoes can breed in just a teaspoonful of water.

Officials urge residents to wear mosquito repellent and drain any standing water.

Dengue fever is widespread in other parts of the world. Whenever it appears in the U.S., local officials hope to contain it. It can cause severe body aches, high fever and rash. Its most severe forms can cause severe bleeding and death.
