Heres what we know so far about the California strain. Both studies suggest the mutated virus has quickly taken hold in California. Researchers hinted that the variant could be better at evading the immune system.
It could be, another variant that's developing right now, that will not be captured and covered by our vaccine. But that study, too, comes with caveats.
The P.1 or Gamma variant that swept Brazil currently accounts for 8.9% of new infections in the US, according to CDC. Commercial and government laboratories test for variants by sequencing the genome of the coronavirus that caused a particular COVID-19 case and looking for mutations and changes in the virus characteristic spike protein. Accessed Feb. 16, 2021. Three of the four never-before-seen mutations on this California strain involve the spike protein, and while the exact implications of those mutations are not yet known for sure, they certainly set off red flags. to Default, About the Viral and Rickettsial Disease Lab, CDER Information for Health Professionals, Communicable Disease Emergency Response Program, DCDC Information for Local Health Departments, Sexually Transmitted Diseases Control Branch, VRDL Guidelines for Specimen Collection and Submission for Pathologic Testing, en

Researchers are sounding the alarm about a COVID-19 variant found in California, warning that emerging evidence shows it could possibly be deadlier, more transmissible and more resistant to vaccines. More information: Tracking SARS-CoV-2 variants (who.int).
But the science is the science. His research suggests this strain of the virus has been circulating in California since May 2020. I would call that a very modest increase, said Joe DeRisi, the co-president of the Chan Zuckerberg Biohub, who has been investigating the variants spread in San Francisco, about the rates of transmission the study found. As ofMarch 29, 2023, for the month of March, XBB.1.5 (84.7%), BQ.1.1 (6.6%), BQ.1 (2.4%), and XBB.1.9.1 (2.0%) makeup the confirmed Omicron cases sequenced in California. Most people who test positive with any variant of COVID-19 typically experience some symptoms for a couple weeks. At-home test brands include BinaxNOW and iHealth. If you only look at the sickest people youre gonna see something different than if you look at the population as a whole, said DeRisi, who was not involved in his colleagues study.

Stay Home if Sick: Stay home if you are feeling sick, test, and isolate for at least 5 days if you test positive. That is a significant increase from November when our sequencing indicated that this variant comprised only 16 percent of the positive tests, said UCSF infectious disease expert Diane Havlir, MD, co-founder of the Unidos en Salud initiative and professor of medicine at UCSF.

The devil is already here, Dr. Charles Chiu, an infectious diseases researcher and physician at the University of California, San Francisco, whos leading an analysis of the new variant, told the Los Angeles Times this week. But, he added, reduced responses are still effective because of the powerful immune response produced by the vaccines. B.1.427/B.1.429 should likely be designated a variant of concern warranting urgent follow-up investigation, the UCSF analysis says.

There have been two studies this week, both from teams at UCSF.
But for now, Gandhi said she was not particularly worried about B.1.427/B.1.429, or the variant that researchers this week flagged in New York. The UCSF researchers found that people infected with this strain carry about twice as much virus in their noses than they do when infected with earlier strains, which would allow them to more easily infect others. Also, New York University researchers tested lambda against the vaccines authorized in the United States and found that the Johnson and Johnson one-dose vaccine was less effective against it and the delta variant compared to the Pfizer and Moderna two-dose vaccines.
However, people infected with, If your illness gets worse, youll want to know so you can take advantage of. Learn more about COVID-19 treatments on the CDPH COVID-19 Treatments page.

Please note that monoclonal antibodies are not currently authorized for pre-exposure prophylaxis or treatment of COVID-19 in any region of the United States due to increasing prevalence of sublineages that have been associated with resistance tothese agents., Potential increased disease severity and risk of death, Minimal impact on antibody treatment effectiveness, Reduced antibody treatment effectiveness, Significantly reduced antibody treatment effectiveness, Moderately decreased antibody treatment effectiveness, Significantly reduced antibody treatment effectiveness, Moderately decreased antibody treatment effectiveness. 2023UC Regents. The findings come as the US ramps up its efforts to track and catalogue various forms of the mutating virus, and raise fresh questions about the circulation of the coronavirus in the country.

But lets wait and see before we worry too much.. Yes and yes. Are they different in any way from previous strains? Im decently confident that this is a more infectious strain of the virus, Eric Vail, the director of molecular pathology at Cedars-Sinai, told The New York Times last month. The WHO determines which variants are of concern based on having one or more of the following changes that could impact global public health. This may be due to decreased virulence of the Omicron variant, greater immunity in the population, or other causes. While the studies are still in the early stages and are yet to be published, scientists looking into the variant say it cant be ignored. Instead of testing right away, you could monitor for COVID-19 symptoms and get tested if any develop. The virus could be becoming more common by some fluke, or because it is slightly more transmissible. All rights reserved. Part of HuffPost Wellness.

The more people who are infected, the more likely we are to see new variants. Here is what we know: Many treatments are still effective against Omicron. Providers should prioritize use of nirmatrelvir/ritonavir (Paxlovid) and remdesivir for treatment of mild to moderate COVID-19 in outpatients at risk for disease progression as these drugs continue to be effective against all Omicron sublineages. The World Health Organization, however, has not placed C.1.2 on its list of variants of interest or of concern.
But some labs, including at the University of California, San Francisco (UCSF), have recently redoubled efforts to figure out which variants are most common in the state. This difference also may play a role in results showing lower severity. By January, the variant accounted for 53% of cases sampled. For the latest national news from NPR and our live radio broadcast, visit LAist.com/radio. Additionally, there are a growing number of both human and animal studies that suggest Omicron is less likely to infect the lower respiratory tract to the degree seen in previous variants such as Delta.

A team of scientists at the University of California, San Francisco (UCSF), tested virus samples from recent outbreaks across the state and found the new variant The New York Times reported this week its now been seen in 45 states and in several places outside the U.S., including Australia, Denmark, Mexico and Taiwan. Still, not every COVID-19 case is genetically sequenced to determine whether it was caused by a variant, so the number of lambda-caused cases could be higher. Modernas bivalent booster is available to ages 18 and older, while Pfizers bivalent booster is for ages 12 and older. The UCSF study did explore that possibility. I am not panicked, and you shouldnt be either, said Monica Gandhi, an infectious disease expert at UCSF. Testing for COVID-19. If you're enjoying this article, you'll love my daily morning newsletter, How To LA. Researchers have found that vaccines may be slightly less effective against the variants first found in South Africa because mutations on the surface spike proteins make that variant less recognizable to the antibodies the immune system produces to find the intruding virus. Continued testing in the area show that a new variant has become much more widespread. A separate analysis of the strain by researchers at Cedars-Sinai Medical Center in Los Angeles was shared there late last month.

But all evidence indicates that the ones currently approved in the US have protected and will continue to protect people against the California variant. Unfortunately, omicron is so easily spread that even those who are fully vaccinated and boosted may get the illness. The first one found that in late November, the B.1.427/B.1.429 variant accounted for 16% of the samples sequenced in San Franciscos Mission district, a low-income, Latino community in a city where many residents are also essential workers.
