The Florida Department of Health in Orange County said Wednesday it has confirmed a human case of locally acquired dengue fever and is now advising residents to take precautions to avoid being bitten by mosquitoes.

The county said it is stepping up its spraying for the mosquitoes known to carry the the disease. According to Orange County Mosquito Control, the species that primarily transmits dengue typically does not travel far.

Both the county and the health department “are coordinating their surveillance and prevention efforts by expanding coverage within affected communities,” a health department spokesperson said in a statement.

The department’s news release did not identify the affect communities nor provide any information about the health of the person who contracted the disease.

Dengue is the most common mosquito-borne disease worldwide, and in the worst cases it can be fatal, but only one in four cases are symptomatic.

According to CDC, the disease can take up to two weeks to develop and the illness generally lasts less than a week. Symptoms include fever, headache, nausea, vomiting, muscle and joint pain and minor bleeding.

“This virus is spread only by mosquitoes,” said Steve Harrison, manager of Orange County Mosquito Control, in a statement. “A person can contract dengue only after being bitten by a mosquito carrying the virus. The mosquito becomes infected by biting a person who has the virus.”

Dengue fever isn’t the only mosquito-borne illness recently reported in Orange County. DOH-Orange announced last week that several sentinel chickens in the county had tested positive for West Nile virus infection.
