Once only seen in hot and steamy tropical or subtropical locales, dengue has been on the rise in parts of the southern United States due to global warming, travel and other factors. While most Americans still contract the disease while traveling to parts of the world where dengue is endemic, there have also been cases of locally acquired dengue in the United States, including a outbreak in Miami.
This can occur when a local mosquito feeds on a person who is infected with dengue and then pass the disease on to others. Spread by a bite from an infected Aedes mosquito, dengue can cause a high feverrash and muscle or t pain.
In severe cases, dengue can cause potentially fatal bleeding and shock. Each year, up to million people will become infected with dengue and about 22, will die from this disease, according to the U. Centers for Disease Control and Prevention. InFlorida saw folks diagnosed with dengue, most of whom had recently traveled to Cuba. This outbreak sired 18 locally acquired cases, including one that resulted in the young Miami woman's death. To determine the source of the infection, doctors reviewed the woman's travel history and performed genetic sequencing of the virus, which confirmed that it was locally acquired.
It should serve as a cautionary tale, said co-author Dr. There is no widely available vaccine to prevent dengue, Morris said. To stave off infection, "use a good bug spray, cover your skin and avoid areas with a lot of standing water," he said. Mosquitoes like to lay eggs near standing water in buckets, bowls, flower pots and vases.
There is no rapid test for dengue either so it can take several days to make a diagnosis, explained study co-author Tyler Sharp, an epidemiologist at the CDC's dengue branch in San Juan, Puerto Rico. A delay in diagnosis played a role in the Miami woman's death.
Treatment involves hydration and close monitoring of vital s. There are ways of reducing the mosquito population that are currently being explored.
For example, as part of a controversial study, Florida released genetically modified male mosquitoes that pass on a gene that kills female offspring before they mature. Only female Aedes aegypti mosquitoes can bite and spread dengue. Unless and until the mosquito population is reduced, "it is very important to be aware of dengue in Florida, Texas and Hawaii as we know that mosquito vector is there," said Yesim Tozan, an assistant professor of global health at the NYU School of Global Public Health in New York City.
Fortunately, most local outbreaks in the United States have been limited as mosquitoes can't fly too far, she said. Mosquito season spans from spring to fall. The U. Centers for Disease Control and Prevention offers more on dengue prevention.

Controlling mosquitoes at the community level has been more challenging, said Sharp. Could I have CAD? Missing Teeth?Lots of oral for a Miami Florida woman
