The GM Mosquitoes Taking on the Zika Virus

Updated on

The first locally transmitted case of Zika virus in the continental U.S. was confirmed in Dallas county on Tuesday, a day after the outbreak and its potential association with birth defects was declared a global public health emergency by the World Health Organization.

A patient became infected after having sexual contact with a sick person who had returned from a country where the virus was present, which means the case is probably a sexual transmission, rather than through a mosquito bite, according to the Texas Department of State Health Services.
