WEDNESDAY, April 7, 2021 (HealthDay News) A “double mutant” variant of the coronavirus has been detected in San Francisco, making it the first time the variant has been spotted in the United States.
The variant has two mutations that help the virus attach to cells and has been driving a surge of COVID-19 cases in India. One of the mutations in the new strain is similar to that found on both the variants first detected in Brazil and South Africa. The second mutation had been found in a variant in California. That mutation is believed to be more transmissible than the original strain of COVID-19, but it is not yet known if it is more resistant to vaccines.

A new study has found that there is a link between the severity of Covid-19 and the levels of antibodies patients carry after recovering from the virus.
The research conducted by Stanford Medicine shows that Covid-19 antibodies preferentially target a different part of the virus in mild cases than they do in severe cases. But all antibodies significantly decrease within months.
The team of researchers studied 254 people who were asymptomatic, had mild, or severe Covid-19. They were identified at the Stanford Health Care Clinic. There’s more to this story Subscribe to News24 and get access to our
