Virus variant from South Africa detected in US for 1st time

COLUMBIA, S.C. (AP) — A new coronavirus variant identified in South Africa has been found in the United States for the first time, with two cases diagnosed in South Carolina, state health officials said Thursday.

Viruses are constantly mutating, with coronavirus variants circulating around the globe, but scientists are primarily concerned with the emergence of three of them. Other variants first reported in the United Kingdom and Brazil were previously confirmed in the U.S. Researchers believe these three variants may spread more easily, and predicted it was only a matter of time before they appeared here.

Also, scientists last week reported preliminary but troubling signs that some of the recent mutations may modestly curb the effectiveness of two current vaccines, although they...
