The San Francisco Chronicle: How scientists are already hunting for California's next COVID-19 variant

California is now sequencing up to 10% of all coronavirus cases, a huge improvement from less than 0.5% at the start of the year. That means the state is now, finally, doing enough sequencing that infectious disease experts say they have a good grasp of the types of variants spreading here, and they are confident that scientists will be able to spot any new mutations quickly. Benjamin Pinsky, MD, PhD, Stanford Medicine associate professor of pathology and of infectious diseases and medical director of the Stanford Clinical Virology Lab, provides comment.
