Mosquito borne illness alert

Fiebre por Dengue

Dengue Fever is a mosquito-borne illness that is commonly found in tropical and subtropical regions. Common symptoms are a high fever of 104 degrees Fahrenheit, severe headache, pain behind the eyes, muscle, bone, or joint pain, nausea and vomiting, swollen glands, and skin rash. The virus is transmitted by the Aedes aegypti mosquito, which is not known to travel far and is commonly active during the day.

Virus del Nilo Occidental

West Nile virus is most commonly spread through the bite of an infected mosquito during Mosquito Season, which typically starts at the beginning of the summer through October. Most people infected with West Nile virus do not develop any symptoms. Symptoms usually start 2-6 days after being bitten by an infected mosquito. Some people develop mild illness with flu-like symptoms and most people will recover completely, but fatigue and weakness can last for weeks or months.

Fumigación Aérea

Aerial spraying is a common mosquito control method used throughout Florida, particularly during periods of elevated mosquito activity or increased disease risk. Airplanes and helicopters can efficiently treat large areas using products approved by the U.S. Environmental Protection Agency (EPA) to mitigate mosquito larvae and adult mosquitoes. These treatments help reduce mosquito populations, limit the spread of mosquito-borne viruses, and protect residents from mosquito-borne illnesses.
