Study Finds Native North American Mosquito Can Transmit Zika

By Josh Lancette

A new study from researchers at the University of North Dakota found that Aedes vexans, a mosquito species indigenous to North America, has the capability to transmit Zika. This is the first native North American mosquito species shown to be able to transmit the virus. The results are published today in the Journal of Medical Entomology.

To test the capability of the species to become infected with the virus, the researchers used mosquitoes collected from North Dakota and Minnesota and fed them blood containing Zika virus. Some (about 3 percent) developed infections. Then, infected mosquitoes were tested to see if they could transmit the virus. Surprisingly, Ae. vexans had a higher transmission rate than Aedes aegypti, which was tested alongside Ae. vexans in the study and is the primary vector of Zika. ......To Read More....
