Traveling to tropical areas? Watch out for Aedes aegypti! October 17, 2013 By Caitlin Bradford Leave a Comment Aedes aegypti in Dar es Salaam, Tanzania by Muhammad Mahdi Karim The female Aedes aegypti mosquito (also called the “yellow fever mosquito”) is responsible for the spread of several tropical fevers, including dengue fever and yellow fever. This mosquito is commonly found in tropical and sub-tropical parts of the world, including the southeastern United States, and was recently discovered in San Mateo County, California. Take precautions: A few simple precautions you can take prior to your trip include: Make sure you have been immunized against yellow fever Bring mosquito netting Bring effective mosquito repellent (CDC recommends the following repellents: DEET, picaridin, oil of lemon eucalyptus, or IR3535) Avoid skin exposure as much as you can. Unfortunately, there are no approved vaccines for the dengue virus, so take precautions if you go anywhere exotic! More information is available in the CDC’s dengue fever/Aedes aegypti fact sheet. Where to watch out for it: In the map below, orange shaded areas are infested with Aedes aegypti mosquitos. Note that the presence of the mosquito indicates a risk for spreading disease, but does not necessarily mean any particular disease is actually present.
