Case 1 of the Brazilian variant S. African Variant in LA – Deadline



Los Angeles health officials reported Wednesday that the county had detected the first cases of the coronavirus found in Brazil and South Africa. While only three samples of the Brazilian virus strain, known as P.1 and one from South Africa called B.1.351, are likely to be far from the only case in the county. hit

Public Health Director Barbara Ferrer noted that because of the cost “Very few samples have been genetically tested this way.” Across the state, only 5% of the tests performed go through genome sequencing, according to California’s senior health officials. Rates are even lower at county level.

California ended most of the COVID restrictions on June 15, Newsom said.

These points also apply to B.1.351, which is thought that the CDC can pass more than 50%. See the chart below.

Even more worrying, however, is that the vast majority of the sample, genetically analyzed in Los Angeles County, last week turned into a mixed concern. The list was led this week by the more infectious UK strain known as B.1.1.7, which this week became the dominant strain in the United States.

While B.1.1.7 has been available in CA for several months now. But the rapid rise in LA was a surprise, because at least four weeks ago a variant known as the locally grown West Coast – B.1427 / B.1429 – had dominated in the state. By a very wide margin The numbers in the chart below show that with the total number of instances of the West Coast species identified in the county to date at 415 and the number of UK strains identified to date at 169, that is 42% of the total. All tests returned in the format B.1427 /B.1429 and 17% B.1.1.7.

The state-level spread is even more pronounced, as of April 1, there were 851 cases of the UK variant in California. However, the same report shows that to date, nearly 10,000 cases of the Western strain have been identified.

But last week in LA found that B.1.1.7 increased to 64% of the detected variable B.1427 / B.1429 at 20%.

The answer may lie in the CDC found that while a UK variant can be more than 50% transmissible, only a West Coast variant is more than 20%, then the UK variants may have overcome an infected West Coast breed. Less infection

The discovery of the Brazilian and South African strains in Los Angeles came just two days after the Stanford Clinical Virology Laboratory confirmed the first California case of the variant. “Two mutations” that occur in India. The Indian mutation is like a major change first seen in the Brazilian and South African strains. Other mutations were also found in the variant first detected in the western variant. It was not clear at this time whether the so-called double mutants were more contagious or resistant to vaccines.

Of course, on Tuesday, California Governor Gavin Newsom announced that the state plans to lift most of the COVID-19 restrictions on June 15 as long as infection and vaccination numbers remain. Probably proceeded in the right direction

That could turn out to be a challenge as some key Covid-19 numbers have stalled in the Los Angeles, Orange County, Bay Area and Sacramento this week.

“Cases are not going to drop any more,” Ferrer said on Wednesday.
