Monroe County, FL—An additional three confirmed cases of Dengue fever have been  found in the Key Largo area through antibody testing. These cases had onset dates of May, June, and July 2020. When these cases were identified previously as persons of interest, the Florida Keys Mosquito Control District was notified, and appropriate mosquito control measures were conducted immediately.

These three additional confirmed cases of Dengue bring the total this year in Monroe County to 45.

The emergence of these Dengue cases reinforces the importance for the public to prevent insect bites and to take basic precautions to help limit exposure. These measures include intact windows and screens and the use of air conditioning, keeping the area around your residence free from containers that collect water, wearing protective clothing and the appropriate use of insect repellents. The Department reminds all residents to drain all standing water at least once per week and designate individuals to share this key responsibility within the business or household.
