The Zika virus has been known for quite some time, but it gained notoriety recently due to its possible linkage to birth defects.

In short, studies are continuing, evidence is mounting, but still not quite a confirmation.
A study published online Wednesday in the New England Journal of Medicine shows the potential range of Aedes aegypti, a tropical mosquito species that is the primary carrier of Zika, blanketing the southern U.S. and reaching as far north as San Francisco; Kansas City, Mo.; and New York City. The likely extent of another Zika-carrying mosquito species, Aedes albopictus, stretched across the Southwest and covered most of the eastern U.S., including northern New England, according to the study conducted by the Centers for Disease Control and Prevention.
Previously, the CDC’s maps showed the ranges of both species generally concentrated in the South, though Aedes albopictus ranged north to New York City and Illinois. The changes were based on new data collected by the CDC and its local partners that show where the mosquitoes have been found. Areas where the mosquitoes are endemic—Puerto Rico, Hawaii and the Gulf states—remained the same.
