It’s called chikungunya virus, and it’s already here in the United States, with 28 cases brought into parts of the country by travelers from 17 countries, mainly in the Caribbean, where more than 103,000 people have been afflicted by the debilitating virus. So far, there have been no documented cases of transmission from one person to another via mosquito in the United States (all the cases have been imported by travelers), but one researcher believes it’s only a matter of time. “There is a high risk that there will eventually be some transmission in Florida,” said Scott Weaver, director of the Institute for Human Infections and Immunity at UTMB. Weaver and others, including the National Institutes of Health, are working on vaccines for the disease, which originated in Africa and has erupted in parts of the globe for centuries. The latest version arrived in the Caribbean last fall and has spread rapidly, Weaver said. The two mosquitoes that carry the virus, Aedes aegypti and Aedes albopictus, are aggressive and bite during the day, Weaver said, meaning that people must protect themselves differently than they would against night-biting mosquitoes that carry an infection such as West Nile.
