Some variants emerge and then disappear. It's late 2025. The omicron subvariant of COVID-19, BA.5, has become one of the dominant strains of the virus in the U.S. Efficacy reduction against symptomatic disease, Lineage B.1 in the PANGO Lineages nomenclature system; includes, BQ.1 and BQ.1.1: BA.5 + S:R346T, S:K444T, S:N460K, BA.2.75: BA.2 + S:K147E, S:W152R, S:F157L, S:I210V, S:G257S, S:D339H, S:G446S, S:N460K, S:Q493R reversion, Recombinant of BA.2.10.1 and BA.2.75 sublineages, i.e. Statewide and county cases, deaths, hospitalizations, and tests, including by vaccination status, gender, and age, State and county data about vaccination, including by race and ethnicity and age, How COVID-19 has affected different communities across the state, In-depth models, dashboards, databases, and information about Californias COVID-19 data reporting, Official California State Government Website, how California genetically sequences positive COVID-19 tests, Data is updated on Fridays. Not for now, Chin-Hong said. You can also sign up to get four free COVID test kits that are mailed to you from the federal government. Thats why it is so important to vaccinate people as quickly as possible, Michels said.

Lambda sparked headlines this summer after the WHO noted its rapid spread in South American countries, including Peru, Ecuador, Argentina and Brazil. These viruses are pretty clever, and they are known to mutate, said Karin Michels, chair of epidemiology at the UCLA Fielding School of Public Health. How long before I had symptoms was I possibly contagious with omicron? Cases, deaths, and tests updated January 12, 2023 at 9:37 AM with data from January 10, 2023. Some are believed, or have been stated, to be of particular importance due to their potential for increased transmissibility, [1] increased virulence, or reduced effectiveness of vaccines against them.

For instance, the CDC initially estimated that about 40.5% of coronavirus specimens circulating nationwide last week were XBB.1.5, but that figure has since been revised downward to 18.3%. The COVID-19 virus is one of numerous infectious diseases circling the globe. Anyone desiring to use or reproduce the data without modification for a noncommercial purpose may do so without obtaining approval. Vaccines Administered. In California, at least 152 cases have been reported, the first as early as September 2020, according to state public health officials. He earned his bachelors degree in journalism from the University of Arizona. Learn more about the COVID-19 bivalent booster and how you can schedule your bivalent booster at UC Davis Health. Some early clues are emerging. The states transmission rates have gone back up to the CDCs red high level from the orange substantial level before Thanksgiving, and Bay Area counties that were in the yellow moderate level are back to orange. A majority of residents of Wyoming, Alabama, Mississippi and Louisiana all "red" states have not been fully vaccinated for the virus, according to Johns Hopkins Universitys Coronavirus Resource Center. Its rise had been most rapid in the Northeast, where XBB.1.5 made up 71.6% of sequenced coronavirus cases in the seven-day period ending Jan. 7, according to data from the U.S. Centers for Disease Control and Prevention. This subvariant will be hard to avoid unless one is being careful, Swartzberg said. Even if masking is not required, consider wearing a mask in public indoor spaces if you or people you live with are at high risk for severe disease. It is, however, a fraction of the highest from last winter, when 513 deaths were recorded the week that ended Feb. 9. Researchers at Cedars-Sinai Medical Center (CSMC) in Los Angeles analyzed COVID-19 strains before and after the surge in cases in southern California in October 2020.

California genetically sequences a sample of positive COVID-19 tests to determine their variant. Whether we know it or not, weve all been living with a string of COVID variants Alpha, Beta, Gamma and Delta, at least. The two COVID-19 vaccines on the market, made by Pfizer and Moderna, train the bodys immune system to attack the spike protein. Here are the biggest impacts. This variant spreads more easily than the original virus that causes COVID-19 and the delta variant. People who have. So far, XBB.1.5 does not appear to cause more severe illness, though research is not yet conclusive, experts say. The 160 deaths are a new peak for L.A. County this autumn and winter. Luke Money is a Metro reporter covering breaking news at the Los Angeles Times. Experts all agree that the subvariant will likely become dominant across the U.S., perhaps by the end of the month, Swartzberg estimated. Rain finally came to California. Viruses mutate into new strains or variants over time. Get the booster. COVID-19 will no doubt still be a major topic of discussion, but I believe and hope that with the right efforts this will be the year the public health emergency officially ends, he said. People check-in at a COVID-19 community testing and vaccination clinic in the Mission District. However previous, studies show that bivalent vaccines result in a stronger immune response against current variants such as BA.5 and help protect against the original strain. Instead of testing right away, you could monitor for COVID-19 symptoms and get tested if any develop. If you have serious symptoms of illness, contact your primary care provider. Good for you, but lets suppose that some other misfortune hits you automobile accident, heart attack, stroke and you end up needing an ICU bed. Sequencing can only be done at specialized labs. That may have happened with a new variant of the coronavirus popping up in California. Dear reader, we're asking you to help us keep local news available for all. Its more contagious and more resistant to existing immunity than any of it coronavirus predecessors. This is a shame as this treatment was very important in protecting many immunocompromised individuals, Swartzberg said. Well, you might find yourself out of luck because across the country, critical care beds are being filled by COVID patients. The lambda variant also known as C.37 was first reported in Peru a year ago and its now spreading across South America, according to the World Health Organization. That span is the rough incubation period for the coronavirus the time between when someone is exposed and when they might be contagious, even if they dont develop symptoms. Yes. A new COVID-19 variant named lambda has arrived in California. Naming schemes developed by other . Flu usually begins with a cough, whereas COVID-19 most often starts with a fever.

Knowing what variants are circulating in California informs public health and clinical action. The variant contains mutations in the spike protein, which the viruses use to attack cell walls, Michels said. The California Department of Public Health said five cases now have been confirmed in Los Angeles County. 72.5% of population vaccinated (with primary series) Although it can vary, people are generally contagious between 1-3 days before omicron symptoms show. Meteorologist Gerry Daz explains what this storm is slated to bring to the Bay Area and if drier air will limit its impacts. The California Department of Public Health works with many partners to achieve a goal of sequencing at least 10% of all positive tests. Thats not idle speculation. It is among the unvaccinated that the virus is free to evolve. Please note that more recent data should be used with caution. Statewide, the seven-day case rate was 78.4 per 100,000 on Nov. 26, and 117 on December 9. Are they different in any way from previous strains? The California COVID Tracker, a joint effort between Chan Zuckerberg Initiative, CZ Biohub, and the State of California has provided free whole-genome sequencing and analysis of the SARS-CoV-2 virus to all California Departments of Public Health and local health jurisdictions since July 2020, enabling officials to better map the virus. Most people who test positive with any variant of COVID-19 typically experience some symptoms for a couple weeks.

To protect against omicron BA.5, health experts recommend the following: Most people who test positive with any variant of COVID-19 typically experience some symptoms for a couple weeks. Japan last week announced its first case, from a woman who arrived from Peru on July 20. At least 1,311 sequenced lambda cases have been reported in at least 40 states since the start of the pandemic, with 18 cases identified in the past four weeks, according to the public virus genetic sequence database GISAID. Nearly 50% of all new coronavirus cases in southern California in January alone are traced to the new variant, CAL.20C, one of the pathologists to identify the strain told Sky News. If the pandemic has taught us anything, it is the interconnection of all the worlds people and nations. California genetically sequences a sample of positive COVID-19 tests to determine their variant. What You Need to Know. The virus that causes COVID-19 is constantly changing, and new variants of the virus are expected to occur. The latest Omicron subvariant perhaps the most infectious yet has gained a foothold in California, a potentially problematic development given the possibility of a post-holiday spike. UPDATE: Here are the latest updates on COVID in the Bay Area and California. We are concerned about its growth advantage, in particular in some countries in Europe and in North America, particularly the Northeast part of the United States where XBB.1.5 has rapidly replaced other circulating variants, she said during a news conference last week. The FDA recently said that it does not anticipate that the drug Evusheld will neutralize XBB.1.5. As of Monday, 4,159 coronavirus-positive patients were hospitalized in California a 6% decrease from two weeks ago. The CDC reported in August that unvaccinated people are almost 30 times more likely to be hospitalized with COVID-19 than those who are fully vaccinated.

More to the point, counties that supported Donald Trump in 2020 have higher COVID death rates than the counties that went for Joe Biden. (In MyUCDavisHealth, click on Visits > Schedule Appointment > COVID Vaccination. CDC data so far suggests that the new bivalent boosters are more effective than previous vaccines in preventing symptomatic disease and hospitalizations, Karan said. LOS ANGLES (CBSLA) - A new COVID-19 variant is setting off alarms around the globe and creating new regulations at home. The World Health Organization is concerned about the risk to life in China amid the coronavirus explosive spread and the lack of outbreak data from the Chinese government. According to the agency, These projections can be uncertain or fluctuate within a wide predictive interval when a variant is just beginning to spread.. That is what is giving it its evolutionary advantage, said UC Berkeley infectious disease expert John Swartzberg. Vaccines administered updated January 12, 2023 at 9:37 AM with data from January 11, 2023, Cases, deaths, and tests updated January 12, 2023 at 9:37 AM with data from January 10, 2023, Details about this data are available in the, Visit My Turn to schedule your vaccination, Official California State Government Website. Deltas aggressive all over the world and lambda hasnt really taken off, Chin-Hong said. Telehealth video visits and Express Care are also available. MOUNTAIN VIEW (KPIX) -- As the Delta variant of the coronavirus fuels an ongoing COVID wave, Bay Area health experts are keeping a close eye on yet another variant: Delta Plus. The state Department of Public Health estimates it accounts for about 7.8% of cases the fourth-most-common subvariant circulating in the Golden State. A CDC report Friday indicated that of 43 reported from Dec. 1-8, 34 involved people who were fully vaccinated at least 14 days before they felt sick or tested positive, including 14 who also had received a booster dose. Over the most recent week, the CDC estimates that XBB.1.5 accounts for 27.6% of new cases across the U.S., the second-highest share of any coronavirus strain. He added that XBBs surges in India and Singapore produced manageable hospitalizations. Officials expect more than 2 billion trips to be made in China during the weeklong holiday, the most important time for visiting family and friends. Scientists are raising concerns over a new coronavirus variant that has been identified in California. Still, the European CDC noted Tuesday that U.S. health officials had scaled back the estimated nationwide proportion of XBB.1.5 from 40% to the current 27.6%, leading to significant uncertainty about the subvariants prospects. Sequencing can only be done at specialized labs. Not all positive COVID-19 tests are genetically sequenced.

What Does That Mean? So, get your shots. Six of the people had a documented previous COVID-19 infection. Since September 2020, the lambda variant has accounted for 152 genetically sequenced COVID-19 cases in California, according to the state Department of Public Health. A group of college students in masks talk to each other in a hallway. It was notorious for being one of the most immune resistant and evasive variants around, but wasnt quite as good at holding on to and infecting cells, he said, which is probably the reason that it never really took off around the world., What makes XBB.1.5 stand out is that it retains the immune slipperiness of XBB, but also adds a mutation that makes it easier to infect cells, Chin-Hong said. This is why vaccines make sense along with other strategies like masking and social distancing. How effective are N95 masks vs. surgical masks vs. cloth masks? The California Department of Public Health has. While most people who become infected will have a mild illness, Chin-Hong said, he is most worried about those who are over 65 and unboosted. Viruses mutate into new strains or variants over time. Sometimes new variants emerge and disappear. Lambda has been around for months, yet it hasnt gained a foothold in California and other states so that should be reassuring, he said. Yes, there are breakthrough cases people who have been vaccinated and still gotten COVID but when they occur, vaccinated patients generally experience milder symptoms. Almost three quarters of eligible Mainers are fully vaccinated now, but that is still below herd immunity. Knowing what variants are circulating in California informs public health and clinical action. A traveler arrives inside Tom Bradley International Terminal at Los Angeles International Airport (LAX) in Los Angeles on Monday. Last month, physicians at UCSF were told to stop prescribing Evusheld and another monoclonal antibody treatment, bebtelovimab, because they are no longer effective against aggressive virus strains. However, theres no need to panic, Chin-Hong said. San Diego County reported its second case late Friday. Experts said its hard to predict, but while an increase in COVID cases is likely due to XBB.1.5, it is not likely to be a large surge. However, in individuals who are older and unboosted, or immunocompromised with weakened or absent immune experience, it will potentially cause serious disease and deaths.. Moderna and Pfizer both have a single-dose bivalent vaccine. Weekly reported COVID-19 deaths which lag case rate trends also are increasing again after a brief dip between Christmas and New Years Day. A year later, her Top 25 Restaurants: Where to Eat in the Bay Area, Regulators look to impose ban on new natural gas water heaters, furnaces, High-speed rail to downtown S.F. Being careful translates to doing the things that we know work, which includes staying up to date on vaccines, wearing a good, well-fitted mask in indoor public spaces, and steering clear of others if you get sick. This is a carousel. Authorities in L.A. County attribute the trend to a variety of tools that werent available previously: an updated COVID-19 booster shot thats a pretty good match to this winters circulating strains; anti-COVID-19 pills such as Paxlovid and molnupiravir that reduce the risk of death; and increased use of masks, particularly in crowded or indoor settings.

Vaccines are especially good in preventing severe disease that may cause hospitalization. In late July, Houston Methodist Hospital reported its first lambda case. According to the CDC COVID tracker, BA.5 is the predominant strain of COVID-19. Express care services are open Monday Friday, 8 a.m. to 8 p.m. and Saturday Sunday 9 a.m. to 6 p.m. There is a also a lag before sequencing data is fully available, so it is likely already more common than the CDC data suggests in the Bay Area., Because of an inadequate amount of PCR testing and insufficient genomic sequencing of positive tests, Swartzberg said, we have a very myopic vision as to how this virus is evolving.. The L.A. County Department of Public Health is urging people returning to work or school from winter break to mask up in indoor public settings for at least 10 days. But last week, the World Health Organization called the XBB.1.5 omicron descendant the most transmissible variant yet, and at a briefing Tuesday urged travelers to wear masks on international flights to help slow its spread. He previously was a reporter and assistant city editor for the Daily Pilot, a Times Community News publication in Orange County, and before that wrote for the Santa Clarita Valley Signal. What are omicron BA.5 symptoms? Doing so could blunt the severity of any potential wave this month, officials said. The new BN.1 omicron offshoot, which the CDC designated a subvariant of concern last weekend, has already taken off. Experts say lambda could be more infectious and resistant to vaccines than the original SARS-CoV-2 virus. What! Numerous variants of the virus that causes COVID-19 are being tracked in the United States and globally during this pandemic. We wont likely see a major spike in COVID cases, but a modest increase in cases in the community, Chin-Hong said. Two studies due to come out soon suggest the variant, which the virologists call B.1.427/B.1. Because of those new genetic markers, the WHO in mid-June declared lambda a variant of interest. The U.S. Centers for Disease Control and Prevention has not yet done the same, in part because so few cases have been reported nationwide. However, the share of cases attributed to it has seemingly risen in recent weeks. A sign announces free COVID-19 Testing in Boyle Heights. Executive director Laurie Thomas then sent out an email Friday morning to her own employees after hearing about this new variant. Some refer to it as the Kraken subvariant, coined by a professor in Ontario, equating its strength to the enormous mythical sea monster, Swartzberg said. Heres what you need to know about lambda. Will it happen in California too? Omicron BA.5 is more likely to cause less severe illness compared to other variants. Still, hospitalizations are increasing across the country, particularly in the Northeast, and more people are dying compared with a month ago, Swartzberg said. So far the delta variant has definitively crowded out other variants nationwide. Updated to include drought zones while tracking water shortage status of your area, plus reservoir levels and a list of restrictions for the Bay Areas largest water districts. Its important to remember that you may be asymptomatic and not know you are infected but still able to spread COVID-19. We believe when reliable local reporting is widely available, the entire community benefits. Testing before big gatherings can also help prevent spread. Nationwide only about 15 of every 1,000 cases are sequenced. Several studies, including one from UC Davis, indicate how effective masks can be in protecting yourself and others. CDC is working with state and local public health officials to monitor the spread of all variants.
