Answer to Case of the Week 17
Answer: Aedes aegypti mosquito
This is one of the most easily recognizable mosquitoes, due to its dark body and distinctive white markings. It closely resembles another human disease vector, A. albopictus (a.k.a. Asian Tiger mosquito), except that the latter has a single straight white stripe on its dorsal thorax instead of lateral curved stripes.
A. aegypti is the vector of Yellow Fever, Dengue, and Chikungunya virus. The former two viruses may be found in South America, and are the answer to the second question of this case.
