Health officials in Florida have declared a local state of emergency in several counties due to an outbreak of dengue fever, a mosquito-borne disease that has reached a record high in the state. The outbreak has been described as "extraordinary" by experts, with 190 cases reported, including one death, in counties such as Pinellas and Hillsborough. This is the second-highest number of cases in the state's history, after 199 cases were reported in 2023.
The majority of cases are linked to people who have recently traveled to areas where the virus is common, such as the Caribbean, Central and South America, Southeast Asia, and Pacific islands. However, experts believe that the outbreak is also due to the proximity of Florida to areas where the virus is spreading, as well as heavy rainfall and high temperatures that have allowed mosquito populations to thrive. The mosquito species responsible for transmitting the virus, Aedes, is found in 75% of the southeastern and southwestern United States.
Dengue fever, also known as "break-bone fever," is a painful disease that causes severe joint and bone pain, as well as symptoms such as fever, rash, headache, and nausea. The disease is usually spread through the bite of an infected mosquito, and there is no specific treatment or vaccine available. Health officials are urging residents to take precautions to prevent mosquito bites, such as using insect repellent and eliminating standing water around homes.
The outbreak in Florida is the second-largest outbreak of dengue fever in the continental United States in recent years, after a major outbreak in Texas and Mexico in 2009. According to the Centers for Disease Control and Prevention (CDC), the number of cases in the United States has increased significantly in recent years, with a 359% increase in 2004 compared to the average annual number of cases over the previous 20 years.
In response to the outbreak, mosquito control teams are conducting inspections and setting up traps to monitor the mosquito population. So far, tests have shown that mosquito samples have come back negative for the virus, and laboratory tests have also shown that the virus is not being transmitted from female mosquitoes to their offspring. Despite these encouraging signs, health officials are warning that the risk of dengue fever will not disappear soon.
Experts believe that the outbreak is a sign of a new normal, with dengue fever becoming a regular occurrence in the state. "This is the new normal," said Dr. Michael von Fricken, an associate professor of environmental health at the University of Florida. "The risk of dengue fever is not going to go away anytime soon." Residents are being advised to take precautions to prevent mosquito bites and to report any symptoms of the disease to their healthcare provider.
The state of emergency declaration allows for additional resources to be deployed to affected areas, including personnel and equipment to help control the mosquito population. Health officials are working closely with local authorities to monitor the situation and respond to any new cases that may arise. The goal is to prevent further spread of the disease and minimize the impact on public health.
Key points
- The outbreak has been linked to travel to areas where the virus is common, as well as to the proximity of Florida to areas where the virus is spreading.
