Experts emphasize that while the vaccines may not be as effective at preventing infections, they still hold up well against serious illness and death. Increased affinity for particular demographic or clinical groups, such as children or immunocompromised individuals. We wont likely see a major spike in COVID cases, but a modest increase in cases in the community, Chin-Hong said. The California Department of Public Health (CDPH) works to protect the public's health in the Golden State and helps shape positive health outcomes for individuals, families and FEATURED PARTNER. Will it happen in California too? The XBB.1.5 variant is taking over on the East Coast. In the region that includes California, Nevada, Arizona, Hawaii and the Pacific island territories, an estimated 7.6% of coronavirus cases over the last week were thought to be XBB.1.5, up from 2.4% the week leading up to Christmas, CDC data show. Those emergent strains, while disruptive, did not come close to spawning the same sort of devastation seen in earlier waves. 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.. Most people who test positive with any variant of COVID-19 typically experience some symptoms for a couple weeks. However, its unclear whether the circulation of this latest strain, XBB.1.5, will alter the trajectory of the COVID-19 pandemic. California genetically sequences a sample of positive COVID-19 tests to determine their variant. L.A. County reported 160 COVID-19 deaths for the week that ended Tuesday.

Pregnant people and their infants are among those considered vulnerable, and a new study suggests the risks of COVID-19 infection in these populations can, in fact, be severe. Amy Osborne, Freelance / Special to The Chronicle, 17 cars broken into on a single night in this San Francisco neighborhood. Several specialized laboratories statewide sequence the genomes of a fraction of all positive COVID-19 tests to determine which variants are circulating. CDC data so far suggests that the new bivalent boosters are more effective than previous vaccines in preventing symptomatic disease and hospitalizations, Karan said. As the third year of the COVID-19 pandemic nears an end, the coronavirus continues to evolve and prove that it has more tricks up its sleeve. All but two of the reported omicron cases were in people who had been vaccinated, and the vaccination status of two others was unknown. Most transmissible COVID variant yet is spreading in California. The California Department of Public Health said five cases now have been confirmed in Los Angeles County. Those at highest risk of death from COVID-19 are older people who are unvaccinated and those who are not up to date on their booster shots. 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. New variants of SARS-CoV-2, the virus that causes COVID-19, are expected to occur. Are COVID-19 vaccines effective in protecting against omicron BA.5? The omicron subvariant of COVID-19, BA.5, has become one of the dominant strains of the virus in the U.S. According to the CDC COVID tracker, BA.5 is the predominant strain of COVID-19. 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. People check-in at a COVID-19 community testing and vaccination clinic in the Mission District. You are safer if you are vaccinated, but you are also safer if your neighbor is vaccinated. 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. Some variants emerge and then disappear. A traveler arrives inside Tom Bradley International Terminal at Los Angeles International Airport (LAX) in Los Angeles on Monday. The newest Omicron subvariant of concern is XBB.1.5. More cases of the omicron variant of the virus that causes COVID-19 continued to surface around the state, from the Central Valley to Southern California, health officials reported. Its since been detected in 29 countries, according to the WHO, including Germany, Spain, the United Kingdom and the United States. 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. It now accounts for at least 86% of Californias sequenced COVID-19 cases and more than 94% of U.S. cases. Learn more about when you should get tested. If you have serious symptoms of illness, contact your primary care provider. These tests are pretty reliable, but they're not perfect. Almost three quarters of eligible Mainers are fully vaccinated now, but that is still below herd immunity. California genetically sequences a sample of positive COVID-19 tests to determine their variant. The California Department of Public Health works with many partners to achieve a goal of sequencing at least 10% of all positive tests.

Officials this season also havent had to deal with the late emergence of a dramatically different variant as they did with the initial version of Omicron in the autumn of 2021, which rapidly spread over the Thanksgiving and then the winter holidays. The new mutation is different from the highly contagious strain first discovered in the United Kingdom, which also has public health officials worried. It is more easily spread than other strains because it evades immunity from past COVID-19 infection and vaccination.

LOS ANGLES (CBSLA) - A new COVID-19 variant is setting off alarms around the globe and creating new regulations at home. If you've been exposed to someone with COVID-19 or are having symptoms, at-home tests can give you a good sense of whether or not you have an infection. The new BN.1 omicron offshoot, which the CDC designated a subvariant of concern last weekend, has already taken off. A slew of alphanumerically designated coronavirus subvariants, each more easily spread than the last, surfaced last year. Watch this video for tips on using at-home tests, Learn what to do if you test positive for COVID-19. Just one-tenth of 1 percent of the cases that are genetically sequenced involve lambda, according to GISAID.

He likened it to a bulldog that wont let go.. As of last Thursday, the CDC is requiring travelers to the US from China, Hong Kong and Macao to take a Covid-19 test no more than two days before travel and provide a negative result before boarding a flight. 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. It will likely not cause more severe illness than our more recent omicron variants given the waves of infection, as well as uptake of vaccinations and boosters in the U.S. as a whole, Chin-Hong said. In its COVID epidemiological update last week, the WHO said the mu variant has been detected in at least 39 countries, including the U.S. But if the virus remains unchecked, it will mutate faster, she said, potentially in a way that the current vaccines can't protect against. The Chilean researchers tested lambda against antibodies from health care workers who received the Chinese-made Sinovac vaccine, finding that the vaccine failed to work as well as it did with the original virus. Lambda sparked headlines this summer after the WHO noted its rapid spread in South American countries, including Peru, Ecuador, Argentina and Brazil. 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. You will then be prompted to answer which vaccines you have received already. That is what is giving it its evolutionary advantage, said UC Berkeley infectious disease expert John Swartzberg. We need to go deeper and look at the reasons for the increases in hospitalization and determine what is happening.. 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. But they dont yet know how lambdas different genetic profile will affect community transmission, severity of symptoms or vaccine resistance around the world. See the data file for data source and disclaimer information. Researchers say its unique new gene deletions and mutations signal that lambda may be more infectious than the original wild type coronavirus and may be potentially resistant to current vaccines, although more studies are needed. 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. At-home test brands include BinaxNOW and iHealth. The seven-day average of daily deaths linked to COVID-19 in the United States is now more than 1,150, according to data for the Centers for Disease Control and Prevention. We might permanently block any user who abuses these conditions. Two studies due to come out soon suggest the variant, which the virologists call B.1.427/B.1. The highly contagious XBB.1.5 strain, the latest in a succession of omicron subvariants that was first detected in the U.S. in October, is quickly spreading. However, in individuals who are older and unboosted, or immunocompromised with weakened or absent immune experience, it will potentially cause serious disease and deaths.. Email: kellie.hwang@sfchronicle.com Twitter: @KellieHwang. As long as we have large numbers of unvaccinated people in the population, everyones risk is raised.

However, the majority of breakthrough infections are not causing severe illness, as compared to early in the pandemic when no one had immunity. What are the differences between flu symptoms and omicron symptoms? Every time COVID-19 infects someone, theres a chance for more mutations, which can allow the virus to keep spreading. The variant contains mutations in the spike protein, which the viruses use to attack cell walls, Michels said. Health officials also have expressed optimism about the lower numbers of COVID-19 deaths reported this fall and winter. 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.

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. It's the most easily spread strain to date and is able to evade immunity from COVID infection and vaccination. If you know you had contact with an infected person, particularly in a higher-risk situation (such as an indoor space for a longer period with others who werent masked), testing is advised. This is why vaccines make sense along with other strategies like masking and social distancing. Every once in a while a virus mutates in a way that helps it survive and reproduce. People who havelong COVID-19 symptomscan experience health problems for four or more weeks after first being infected,according to the CDC.
