The largest variant of the coronavirus in California has acquired dangerous mutations

Scientists have recently reported that a new variety from California has become a mainstay in that state. In a study of their database, they were first identified in the early summer of last year, lying dormant until the winter rose sharply across the state. According to researchers at the University of California, San Francisco (UCSF), this particular variation grew from 0 percent in September to 50 percent at the end of January.

California reported 669 COVID-19 deaths, the second highest daily death count, on Saturday, Jan. 16, and the country’s most populous county announced its first case of a more susceptible series. movement of the coronavirus.

This new variant has been found in many other U.S. states and has reached locations as far afield as the UK, Singapore, and Australia. It has mutations in its spike protein that seem to make it not only more potent but also help it avoid antibodies generated by the COVID-19 vaccines.

Scientists have named the new variant as the CAL.20C variant covering series B.1.427 and B.1.429. It is associated with a mutation in its receptor binding domain called L452R.

Professor Charles Chiu is the lead author of a study that reports on the growth of the CAL.20C variant among 8,000 residents in the Mission Area of ​​San Francisco, and found the initially changed on December 31. He told the media, “This change is worrying. because our data show that it is more contagious, more likely to be associated with severe disease, and at least to some extent opposed to neutralizing antibodies. … The devil is here already. I wish it were different. But science is science. ”

Speaking to the Los Angethe Times, Dr. Chiu pointed out that it would be necessary to reduce diseases as much as possible while moving fast in order to vaccinate the population. This assessment was raised by Dr. Angela Rasmussen, a Georgetown University geologist, said, “The [UCSF] decisions deserve a closer look at this change. … They emphasize the importance of removing all stops in terms of both exposure reduction and increased vaccination circulation and accessibility. ”

In a study of 324 people with COVID-19 treated at UCSF clinics or its medical centers, after adjusting for various variables, such as age, gender, and race, those infected with the difference CAL.20C is almost five times more likely to require ICU admission and 11 times more likely to die. A study from nasal swabs also showed that patients with CAL.20C carry twice the viral load. Moreover, during in vivo studies, the variant was four times more likely to receive antibodies from previously infected people and twice as likely to receive antibodies from people who received the Pfizer and Moderna vaccine.
