Cases of ‘Breakbone Fever’ Spreading Locally in Florida for First Time in 15 Years

Dengue Fever Cases Reported in Florida: First Locally Transmitted Infections in Years

Florida has seen an alarming rise in locally acquired cases of dengue fever this year, with the latest figures indicating ten confirmed instances of the mosquito-borne illness. This includes the first reported case in Pinellas County in over 15 years, highlighting a concerning trend of dengue transmission within the Sunshine State.

Dengue fever, which is often dubbed “breakbone fever” due to the severe joint and muscle pain it can induce, is typically transmitted by the bites of infected mosquitoes, particularly the Aedes aegypti and Aedes albopictus species. The symptoms of this disease range from mild to severe, manifesting as high fever, rash, extreme fatigue, and considerable body aches.

Officials reported that eight of the locally contracted cases were identified in Hillsborough County, while two were found in Pinellas County. Alyssa Berro, the mosquito control manager for Pinellas, explained, “Pinellas doesn’t have any modern history of having dengue in the county. This indicates that someone returned from abroad after being bitten, and upon being bitten again by our local mosquitoes, started the transmission here.”

Despite Florida’s traditionally warm climate being conducive to the Aedes mosquito populations, dengue fever is not endemic to the region. Historically, most cases in the United States arise from individuals who have become infected while travelling abroad to areas where the virus is prevalent.

The Centers for Disease Control and Prevention (CDC) has raised concerns regarding an “unusually high number of dengue cases among U.S. travellers” this year, emphasising that precautions are vital to mitigate the risk of domestic outbreaks. So far in 2023, the CDC reported over 1,470 cases of dengue across the United States, with about a quarter of those infected by mosquito bites developing symptoms.

Residents in at-risk areas such as Florida are urged to take preventative measures seriously. The CDC recommends wearing protective clothing, opting for long sleeves and trousers, and utilising insect repellents that contain DEET, Picaridin, or oil of lemon eucalyptus. It is important to note that the latter two ingredients are not suitable for children under three years old, calling for caregivers to exercise caution.

Local health departments are on high alert, with an increased focus on mosquito control efforts and public health measures. Mosquito surveillance and control practices are essential in curbing the population of these disease-carrying insects. Authorities have ramped up their efforts in affected areas to prevent further spread of the virus.

Treatment for dengue fever generally involves managing symptoms, as there is currently no specific antiviral therapy for the disease. Patients are typically advised to rest, remain hydrated, and use acetaminophen to alleviate pain and fever. Those who experience severe forms of the illness may require hospitalisation.

As dengue fever cases continue to rise, public health officials stress the importance of remaining vigilant when travelling to and from areas where the disease is prevalent. With travel increasing globally, especially post-pandemic, the risk of imported cases leading to local transmission remains a pressing concern.

The ongoing situation serves as a reminder for communities to stay informed and prioritise preventive measures to protect themselves and their neighbours from mosquito-borne diseases. As Florida navigates this fresh wave of dengue fever, active participation from all residents becomes crucial in halting its spread.
