Virus variant from South Africa detected in US for 1st time
COLUMBIA, S.C. — A new variant of the coronavirus emerged Thursday in the United States, posing yet another public health challenge in a country already losing more than 3,000 people to COVID19 every day.
The mutated version of the virus, first identified in South Africa, was found in two cases in South Carolina. Public health officials said it's almost certain that there are more infections that have not been identified yet. They are also concerned that this version spreads more easily and that vaccines could be less effective against it.
The two cases were discovered in adults in different regions of the state and do not appear to be connected. Neither of the people infected has traveled recently, the South Carolina Department of Health and Environmental Control said Thursday.
“That's frightening,” because it means there could be more undetected cases within the state, said Dr. Krutika Kuppalli, an infectious diseases physician at the Medical University of South Carolina in Charleston. “It's probably more widespread.”
The arrival of the variant shows that “the fight against this deadly virus is far from over,” Dr. Brannon Traxler, South Carolina's interim public health director, said in a statement. “While more COVID-19 vaccines are on the way, supplies are still limited. Every one of us must recommit to the fight by recognizing that we are all on the front lines now. We are all in this together.”
Viruses constantly mutate, and coronavirus variants are circulating around the globe, but scientists are primarily concerned with the emergence of three that researchers believe may spread more easily. Other variants first reported in the United Kingdom and Brazil were previously confirmed in the U.S.
As the variants bring a potential for greater infection risks in the U.S., pandemic- weary lawmakers in several states are pushing back against mask mandates, business closures and other protective restrictions ordered by governors.
States including Arizona, Michigan, Ohio, Maryland, Kentucky and Indiana are weighing proposals to limit their governors' abilities to impose emergency restrictions. The Wisconsin Legislature was expected to vote on repealing the governor's mask mandate. Pennsylvania lawmakers are considering a constitutional amendment to strip the governor of many of his emergency powers.
Governors argue that they need authority to act swiftly in a crisis, and limitations could slow critical emergency responses.
Meanwhile, Nebraska health officials said the state could be days away from lifting restrictions on indoor gatherings, citing a low percentage of COVID- 19 hospitalizations. Other states seeing declining infections are also loosening limitations on restaurants and other businesses, though experts have warned the public to stay vigilant about masks and social distancing or risk further surges.
In South Carolina, the state health agency said the variant was found in one person from the state's coastal region and another in its northeastern corner. The state gave little other information, citing privacy concerns, though Traxler said neither of the people was contagious any longer.
“Both were tested very early in the month, and my understanding is that both are doing well,” Traxler said.
