A rapidly emerging mutation of the coronavirus has been detected in more of Santa Clara County’s recent case outbreaks. On Tuesday, California Health and Human Services Secretary Dr. Mark Ghaly confirmed the L-452-R variant has been found within outbreaks at several local jails and congregate care facilities. Earlier this week, public health officials announced it played a role in the massive San Jose Kaiser Permanente outbreak, where more than 90 employees and dozens of patients tested positive, and one employee died. This form of the virus only appeared in a trace amount of cases early last year, then began to take off in the fall. It is unclear if this strain is more contagious or deadly.
