Aedes aegypti

…spread of Aedes mosquitoes, especially A. aegypti and A. albopictus, which are native to Africa and Asia, is suspected of facilitating the uptake and transmission of pathogens by endemic Aedes species. Infected humans may also play a role. For example, A. polynesiensis is a suspected vector of Zika virus in…

…of which are the mosquitoes Aedes aegypti and A. albopictus. The original vector of the virus was A. aegypti, which is native to Africa and India. However, genetic mutations enabled viral adaptation to A. albopictus, which is native to Asia. This mosquito is considered an invasive species, and factors involving…

…to Africa and India, where Aedes aegypti, the original mosquito vector described for chikungunya virus, thrived. However, viral mutation, climate change, and human travel and migration have caused shifts in the geographic occurrence of chikungunya fever. Mutations in the virus have enabled it to infect a second vector, Aedes albopictus,…

…areas is the yellow-fever mosquito, Aedes aegypti. The Asian tiger mosquito, A. albopictus, is another prominent carrier of the virus. A mosquito becomes infected only if it bites an infected individual (humans and perhaps also certain species of monkey) during the first three days of the victim’s illness. It then…

For example, although A. aegypti is the principal vector of dengue viruses in Africa and the Americas, A. albopictus can also transmit the disease to humans in those regions. In French Polynesia, A. polynesiensis serves as an endemic dengue vector. Dengue outbreaks have also been

…a mosquito now known as Aedes aegypti. In his investigation of Finlay’s theory, U.S. Army pathologist and bacteriologist Major Walter Reed demonstrated in 1900 the transmission of yellow fever from one human to another through the bite of A. aegypti. Reed was further able to show that mosquitoes were the…

…humans by Aedes mosquitoes, primarily A. aegypti and A. albopictus. In rare instances, the disease may be transmitted between humans perinatally (between mother and fetus), sexually, or via blood transfusion.

The principal vectors, A. aegypti and A. albopictus, are native to Africa and Asia, respectively. However, both species have spread from those regions to distant areas, including the South Pacific and the Americas. In addition, Zika virus may be readily taken up and transmitted by endemic Aedes species;…

…fever is transmitted by a mosquito, later known as Aëdes aegypti.

…mosquito, Stegomyia fasciata (later renamed Aedes aegypti), and that the same result could be obtained by injecting into a volunteer blood drawn from a patient suffering from yellow fever. Reed found no evidence that yellow fever could be conveyed by fomites, and he showed that a house became infected only…
