MARTIN COUNTY, FL (WFLX) - Martin County health officials said Wednesday morning there are now 20 confirmed cases of dengue fever. They said all were exposed in the Rio, Jensen Beach area and had no international travel.
Of the cases, 13 are Martin County residents, two non-Florida residents, one Palm Beach County resident and four St. Lucie County residents who visited Martin County, the health department said.
In response to the outbreak, survey teams started going door-to-door in parts of Rio and Jensen Beach talking with some residents and testing their blood.
The two latest cases were confirmed following routine surveillance and were not part of the current community survey, the health department said.
"In order to stop the spread of dengue fever, we must stop the mosquito bites," said Karlette Peck, Health Officer, Florida Department of Health in Martin County in a statement to the media. "We urge everyone in the Rio and Jensen Beach area to take this seriously. Simple precautions, such as the use of mosquito repellent will help to keep residents and visitors healthy. This is especially important when people are working outside or are active in and around their homes. It is also critical that people continue to drain standing water in anything that accumulates water around their homes."
According to the Centers for Disease Control and Prevention as many as 100 million people are infected yearly.
Symptoms of dengue fever include headache, high fever, and joint pain that usually last about a week.
