UCSD says new strain of coronavirus found in Japan also likely present in U.S. A new variation of the coronavirus discovered in Japan is “very likely already in the U.S.” as well, according to Davey Smith, director of infectious diseases at UC San Diego. “The current qPCR tests may not pick up this variant,” said Rob Knight, an infectious disease expert at UCSD. “We are rapidly scaling up sequencing efforts between Scripps Research and UCSD, which will allow us to see all genome variants.” Knight Lab January 19, 2021 0 Share
