Dengue fever is the most common viral disease transmitted by arthropods in the world and is endemic in more than 110 countries, infecting 50 to 100 million people worldwide a year, leading to half a million hospitalizations, and approximately 12,500–25,000 deaths. The disease's symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. It is estimated that due to a combination of urbanization, population growth, increased international travel, and global warming, the incidence of the dengue fever has risen 30 fold.
