Orange County Battles Mosquito-Borne Diseases: Dengue Fever and Sloth Fever

Orange County is currently grappling with a significant public health challenge posed by mosquito-borne diseases, notably dengue fever and the oropouche virus, commonly referred to as sloth fever. The county’s health authorities have recently identified two travel-related cases of the oropouche virus within the region. This discovery has heightened the urgency for comprehensive mosquito control measures, particularly given the interconnectedness of global health and the rapid spread of such diseases. The county’s government division is actively engaged in spraying neighborhoods and educating residents on mosquito prevention strategies. Their overarching goal is to safeguard the health of both local residents and visitors, emphasizing the importance of community involvement in these preventive efforts.

The oropouche virus, which is transmitted through the bites of infected biting midges and certain mosquito species, has been a growing concern. Often referred to as sloth fever due to its transmission cycle from animals to mosquitoes to humans, the virus can only be passed to humans through an insect bite. Unfortunately, there is no specific treatment or preventative medicine available for this virus. Symptoms of oropouche virus infection include high fever, headache, muscle aches, stiff joints, nausea, vomiting, chills, and sensitivity to light. In severe cases, the virus can lead to meningitis, and there have been reports of fatalities, particularly in Brazil. In the United States, most cases have resulted in fever and other symptoms that resolved without specific treatment, although some individuals have experienced a recurrence of symptoms after initial recovery.

As of August 24th, the Centers for Disease Control and Prevention (CDC) has reported cases of the oropouche virus in several counties across Florida, all linked to individuals who traveled to Cuba. This has prompted Orange County to intensify its mosquito control efforts. Residents are encouraged to call the county’s 311 hotline to report mosquito issues in their homes or communities. The mosquito control teams are employing various methods, including spraying and public education about prevention techniques, to mitigate the spread of these diseases. The county’s proactive stance underscores the critical need for vigilance and community cooperation in addressing this public health threat.

Orange County Mosquito Control has issued a warning to residents following the detection of two cases of sloth fever in the Lockhart/Rosemont area of Orlando. These cases were likely transmitted by mosquitoes from individuals who had traveled overseas. Since the first case was reported, mosquito control teams have been working diligently in the affected area, searching for breeding grounds for the Aedes aegypti mosquito. This particular mosquito species is known to transmit not only dengue fever but also yellow fever and other viruses. Residents are advised to eliminate standing water around their homes, as even small amounts can serve as breeding sites for mosquitoes.

The CDC issued a health advisory in August regarding the rising cases of sloth fever in the Americas, with over 8,000 cases reported this year, including two deaths. In response, county crews are working tirelessly, day and night, to spray for mosquitoes in affected areas. They are targeting bushes, neighborhoods, and any locations where mosquitoes are likely to thrive. These efforts are in line with CDC recommendations, and residents are encouraged to report any mosquito-related issues they encounter by contacting the county’s 311 hotline. The focus remains on identifying and eliminating breeding areas to prevent further spread of these mosquito-borne illnesses.

Officials believe that the recent cases of sloth fever in Orlando were contracted by travelers returning from overseas. This highlights the importance of mosquito control measures in preventing the spread of diseases brought in by international travel. Removing standing water is a crucial step in this process, as it helps to eliminate potential breeding sites for mosquitoes. The CDC’s warning about sloth fever cases in the Americas has prompted increased efforts from mosquito control teams across the region. Residents are urged to remain vigilant and proactive in reporting any mosquito-related issues to help curb the spread of these diseases.

In addition to the oropouche virus, Orange County is also dealing with cases of dengue fever. The county’s mosquito control teams are taking decisive action to eliminate the mosquito species responsible for transmitting dengue. This decision follows the confirmation of two local cases of dengue fever. Both daytime and nighttime crews are implementing control measures recommended by the CDC to prevent further local transmission of the virus. Dengue fever, a mosquito-transmitted disease typically found in tropical and subtropical regions, has two forms: a mild version causing high fever and flu-like symptoms, and a severe form known as dengue hemorrhagic fever, which can result in serious bleeding, a rapid drop in blood pressure, and even death.

Many people infected with dengue may not show any symptoms at all. When symptoms do occur, they often include fever, headache, muscle pain, nausea, and rash, usually appearing 4-10 days after being bitten by an infected mosquito. These symptoms can easily be mistaken for the flu, making it essential for individuals to seek medical attention if they suspect they have been infected. Orange County’s mosquito control manager, Steve Harrison, emphasized the importance of swift action to contain and eliminate the mosquito breed responsible for transmitting the virus. The control measures being implemented are in line with those recommended by the CDC, aiming to prevent further local transmission of dengue.

Miami-Dade County has reported the highest number of dengue cases in the United States in 2024, according to data collected by the CDC. As of May 24, Miami-Dade County has reported a total of 74 cases, accounting for 41% of Florida’s 180 cases. Of these, only seven cases were acquired locally, with the remainder being travel-associated. Broward County has reported 30 cases, with a significant number of infections acquired in Cuba and Brazil. New York ranks second in the number of dengue infections, with a total of 114 cases, none of which were acquired locally. Puerto Rico, however, reported the most infections among all US jurisdictions, with over 1,000 cases.

The CDC notes that dengue symptoms typically start within a few days of being bitten by an infected mosquito, although it can take up to two weeks for symptoms to develop. Common symptoms include fever, headache, joint and muscle pain, rash, and nausea. Severe cases can lead to shock, internal bleeding, and even death. Some individuals may not experience any symptoms at all, making it crucial for those who have traveled to areas with a high number of dengue cases to seek medical attention if they develop symptoms. Prevention methods include avoiding mosquito bites and properly disposing of any standing water to eliminate potential breeding sites.

In conclusion, the ongoing battle against mosquito-borne diseases in Orange County underscores the importance of community involvement and proactive measures in preventing the spread of these illnesses. With the interconnectedness of global health and the increasing incidence of diseases like dengue fever and sloth fever, it is essential for residents to stay informed and take necessary precautions. By eliminating standing water, reporting mosquito issues, and adhering to CDC recommendations, the community can work together to protect public health. The efforts of mosquito control teams, combined with public awareness and cooperation, are vital in mitigating the impact of these diseases and ensuring the well-being of both residents and visitors in Orange County.
