Dengue

Dengue fever is a viral disease transmitted by mosquito bites that occurs worldwide in tropical and subtropical areas. Major epidemics have occurred in recent years in Southeast Asia, sub-Saharan Africa, and Central and South America. Travelers from the US and Europe have contracted the disease while vacationing at popular tourist destinations in the Caribbean, Mexico and Southern Asia. Prevention of mosquito bites during the day, particularly in early morning and late afternoon, is the only way to protect against dengue fever; no vaccine is currently available.
