Dengue in the USA



Dengue is a viral disease vectored by mosquitoes, including the invasive Asian tiger mosquito. Before the presence of the Asian tiger mosquito, many areas of the US lacked mosquito species that were competent to vector Dengue. In the presence of the Asian tiger mosquito, visitors who have contracted Dengue elsewhere can spread the disease to the local mosquito population. The island of Hawaii is currently experiencing an outbreak of dengue with around 130 identified cases. The outbreak started when an infected tourist visited the island. The cases so far have been mild. Officials work to isolate infected individuals from the mosquito population. The use of repellents is important in disrupting the transmission cycle. If the number of cases remains low, it is possible that the current outbreak will end. Efforts to reduce the population of adult mosquitoes may also slow transmission. Abnormally wet weather has led to an increase in mosquito population that makes transmission more likely.
