The source report describes a record number of dengue cases in Florida, with nearly 500 reported to the CDC at the time of publication and one death. It says dengue virus had been detected in local mosquitoes, meaning some infections occurred without international travel; prevention relies on avoiding bites and removing mosquito breeding sites.

Florida had nearly 500 dengue cases reported to the Centers for Disease Control and Prevention at the time of a Good Housekeeping report, which also cited one death and evidence that local mosquitoes were carrying the virus. Local transmission means people can become infected without traveling abroad, making mosquito-bite prevention relevant to residents and visitors.

The report described Florida’s case count as a record for the state that year, but it did not provide a specific reporting date or a current CDC tally. The figure should be read as a snapshot from the report, not as a present-day total. It also said dengue virus activity had been found in the local mosquito population, a sign that some infections were being transmitted within the United States.

Dengue is spread through bites from infected Aedes mosquitoes, especially Aedes aegypti. University of Georgia public health extension specialist and entomologist Elmer Gray told Good Housekeeping that a mosquito can acquire the virus by biting an infected person and then pass it to another person. The report also identified Aedes albopictus, or the Asian tiger mosquito, as another species capable of transmitting dengue.

Many people infected with dengue have no symptoms or only mild illness, according to Rutgers Global Health Institute assistant professor Bobby Brooke Herrera. Symptoms can include muscle and bone pain, pain behind the eyes, nausea, vomiting, swollen glands and rash, and often begin about a week after a bite. Some cases can become severe. The report says infants, pregnant people, older adults and people with certain medical conditions face greater risk of severe disease.

Local Mosquitoes Change the Risk

Dengue risk for people in the United States is often associated with travel to tropical and subtropical regions. The reported presence of virus in Florida’s local mosquitoes changes that picture: travel abroad is not required for an infection where local transmission is occurring. Visitors and residents can face exposure in affected areas, particularly when spending time outdoors.

The report’s count and death toll are tied to its publication period, and should not be used as a measure of the current outbreak. Still, the account underscores why preventing bites matters: dengue has no specific treatment, and although many cases are mild, some can become life-threatening. Local transmission also makes practical precautions relevant to households, not just people returning from travel.

How Dengue Spreads in Florida

Dengue is caused by four related virus types, known as serotypes. Herrera told Good Housekeeping that the viruses circulate in tropical and subtropical regions and that infection with one type does not rule out later infection with another. The report says a later infection with a different serotype may be associated with more serious illness in some people.

In the United States, many dengue infections are associated with travel, but the report said Florida had seen local transmission during the period covered. It also noted that people traveling to Florida for vacations or seasonal stays could encounter mosquito exposure. The article’s source material does not supply county-level case details, the date range for the reported count or a breakdown between travel-associated and locally acquired cases.

For prevention, the report recommends EPA-registered insect repellents containing ingredients such as DEET, picaridin, IR3535, oil of lemon eucalyptus or 2-undecanone. Apply products according to their labels, including instructions on reapplication. If using sunscreen, apply it first, allow it to dry, then apply repellent. Permethrin-treated clothing and loose-fitting, light-colored long sleeves and pants can add protection; repellent intended for skin should not be confused with products meant for clothing.

““The local mosquito population has picked up and is carrying the virus.””

What the Report Does Not Establish

The source report does not state the exact date when nearly 500 cases were counted, identify the reporting period or provide a link to a contemporaneous CDC dataset. It also does not specify how many cases were locally acquired, where within Florida transmission was detected, or whether the one reported death was confirmed as caused by dengue. Those details cannot be inferred from the supplied material, and the figures may have changed since publication.

The article gives no current case update, forecast or information about whether local transmission is continuing. Readers seeking present-day numbers should consult the CDC and Florida health authorities. The source says there is no dengue vaccine available in the United States and no specific medicine to treat the infection; it does not provide updated guidance on vaccine eligibility or later changes in treatment recommendations.

Check Local Health Updates

People in Florida should follow updates from state and local health departments and the CDC for current case totals, affected locations and mosquito-control guidance. Because the source’s count is a publication-time snapshot, it does not establish the outbreak’s status today. Anyone with possible dengue symptoms, especially after mosquito exposure in an area reporting transmission, should contact a health professional.

The report says care for dengue generally involves rest, fluids and acetaminophen for fever or pain. Herrera cautioned against aspirin and ibuprofen in the report; people who may have dengue should ask a clinician about safe medicines rather than self-treating. Severe symptoms or rapid worsening require prompt medical attention.

Key Questions

Can someone get dengue in the United States without traveling?

Yes. The report says local mosquito transmission was occurring in Florida during the period it covered, meaning a person could be infected after being bitten in the United States. The source does not establish where transmission is occurring now.

What are common dengue symptoms?

Symptoms can include muscle or bone pain, pain behind the eyes, nausea, vomiting, swollen glands and rash. Some infected people have no symptoms or only mild illness. The report says symptoms may begin about a week after an infected mosquito bite.

How can I reduce the chance of a mosquito bite?

Use an EPA-registered repellent according to its label, wear loose-fitting long sleeves and pants, and consider permethrin-treated clothing. If applying sunscreen too, put it on first, let it dry and then apply repellent. Remove standing water around the home where mosquitoes may breed.

Is there a dengue vaccine or specific medicine in the United States?

The source report says no dengue vaccine was available in the United States and no specific medicine treats dengue. It describes supportive care such as rest, fluids and acetaminophen, with medical advice recommended for suspected infection.
