But much remains unknown how or if XBB.1.5 may affect disease severity or whether generally waning immunity from vaccines or a previous brush with the coronavirus will leave the population more exposed to infection. Every once in a while a virus mutates in a way that helps it survive and reproduce. The first case was found in September, with another 10 in March, 88 in April, 43 in May, eight in June and, most recently, two cases in July. Throughout December, people ages 50 and older had the highest rate of coronavirus cases, hospitalizations and deaths in L.A. County. This is compared to surgical masks that reduce the rate of infection by about 60-70%, and greater than 80% for N95s. To help limit spread of COVID-19, we have policies for visits to our hospital and outpatient clinics. The recently authorized booster vaccine protects against the original SARS-CoV-2 virus and the more recent omicron variants, BA.4 and BA.5.

It could be, another variant that's developing right now, that will not be captured and covered by our vaccine. 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. 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. The FDA recently said that it does not anticipate that the drug Evusheld will neutralize XBB.1.5. This chart is made using California Department of Public Health (CDPH) Genomic Surveillance Data. Hospitalizations statewide have stabilized after an autumn rise. Sequencing can only be done at specialized labs.

Does omicron BA.5 cause more severe illness than other strains of COVID-19? The CDC has reported a doubling time of nine days for XBB.1.5, referring to the number of days it takes for cases, hospitalizations and deaths related to a virus variant to double. Use of this data is subject to the CHHS Terms of Use and any copyright and proprietary notices incorporated in or accompanying the individual files. What about the bivalent booster? However, its unclear whether the circulation of this latest strain, XBB.1.5, will alter the trajectory of the COVID-19 pandemic. In November 2022, 10% of 169,971 cases in California were sequenced, and this percent is expected to increase in coming weeks as more sequence data becomes available. Drugs such as Paxlovid and molnupiravir are free and widely available, but officials say doctors are not prescribing them as much as they should. 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.. This is why vaccines make sense along with other strategies like masking and social distancing. 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.
