Important mosquito-borne viruses that are transmitted between humans via vector mosquitoes have a way of appearing or reappearing in the United States and in the Americas. Dengue is a classic example. Ships brought mosquitoes (Aedes aegypti) and viremic individuals to ports in the U.S. more than 300 years ago. Benjamin Rush, MD, a signatory to the Declaration of Independence, described a major dengue outbreak in Philadelphia in 1780. Cases continued to occur in the eastern U.S. port cities and Gulf Coast states for more than 150 years with a dramatic outbreak in New Orleans involving an estimated 40,000 people in 1873. Outbreaks finally ended in the country for a time in 1945. However, the mosquito vector did not disappear in Texas and the Gulf Coast states, and an additional dengue virus vector, the Asian tiger mosquito, Aedes albopictus, was introduced into the U.S. in the 1980s and spread.
