California covid strain?

Scientists in California believe there is a homegrown coronavirus strain in the state that could be responsible for the dramatic rise in cases, a report said Sunday.

Two separate research groups have discovered the apparent California strain while looking for the new variant that is believed to have come from the United Kingdom, according to the Los Angeles Times.

The supposed California strain is in the same “family tree” as the UK strain and could be behind the state’s spread over the past few months, the paper said.

One of the labs that discovered the strain, Cedars-Sinai Medical Center in Los Angeles, said it amounted to 24 percent of about 4,500 viral samples gathered throughout California in the last weeks of 2020.

Another analysis found that 25 percent of 332 samples taken in Northern California were of the new strain.

Did the Spanish Flu mutate like this?  If not then we're in uncharted territory.  This little monster is mutating faster than we can get cures.  I wonder if we're on the verge of a human culling?
