A 3rd variant from South Africa, which popped up in 20 nations, has not been detected but on this nation, Walensky added.
“The variants which were recognized not too long ago appear to unfold extra simply and are extra transmissible, which may result in an elevated variety of instances and elevated stress on our already taxed well being care system,” Walensky mentioned.
Nonetheless, these variants don’t appear to have the ability to outmaneuver both the Pfizer or Moderna vaccines, mentioned Dr. Anthony Fauci, director of the U.S. Nationwide Institute of Allergy and Infectious Ailments, and President Joe Biden’s chief medical adviser.
