US has 'good shot' to get all kids in school by fall, says Biden's surgeon general pick
U.S. President Joe Biden's nominee to become surgeon general, Dr. Vivek Murthy, told The Washington Post Live that he thinks the United States has a "good shot" to get all kids in school by the fall.

Murthy, a physician who served as U.S. surgeon general from 2014 to 2017, said the nation must takes these steps: vaccinate staff; ensure schools have the resources to take precautionary measures including PPE and tests; and lower "background rates of infection," which he defines as rates of transmission in the community.

"When those rates are really high, it makes it harder to prevent infection from getting into the school," Murthy said. "So we've got to get that background infection rate down, and we've got to vaccinate teachers and other educators and staff in schools. As well as, when we do have the opportunity to vaccinate kids when the trial data comes through and shows that it is safe and effective, that we've got to start vaccinating children, too."

South Africa variant found in US for 1st time
The United States’ first known cases of the South Africa variant of the novel coronavirus have been confirmed in two people in South Carolina, according to the South Carolina Department of Health and Environmental Control.
"There is no known travel history and no connection between these two cases," the department said in a statement Thursday.
Both cases are among adults, one who is from the Lowcountry region and another who is from the Pee Dee region, according to the department.
The U.S. Centers for Disease Control and Prevention said it's aware of the cases and it "recommends that people avoid travel at this time."
The so-called B1351 variant, first identified in South Africa, has been detected in more than 30 countries, according to the South Carolina Department of Health and Environmental Control.
"Experts agree that existing vaccines work to protect us from this variant, even if we don’t know precisely how effective they are," the department said. "At this time, there’s no evidence to suggest that the B.1.351 variant causes more severe illness."

During an interview Thursday on ABC's "Good Morning America," Dr. Anthony Fauci, chief medical adviser to U.S. President Joe Biden and the nation's leading infectious disease expert, said the South Africa variant "troubles" him.
Fauci said lab experiments show the neutralizing antibodies induced by existing COVID-19 vaccines are "diminished by multifold" when tested against the B1351 variant
"It's still within the range of what you would predict to be protective," he said, "but I take no great comfort in that."
However, scientists are already working on vaccines that will specifically target the South Africa variant, according to Fauci.
"May not be necessary," he said, "but if it is we'll already be on the road to be able to give people a boost that directs against the South African isolate."
