  2. The Delta variant causes more infections and spreads faster than earlier forms of the virus that causes COVID-19. It might cause more severe illness than previous strains in unvaccinated people. Vaccines continue to reduce a person’s risk of contracting the virus that cause COVID-19, including this variant.

  3. Sep 20, 2021 · Vaccines continue to reduce a person’s risk of contracting the virus that cause COVID-19, including this variant. Vaccines are highly effective against severe illness, but the Delta variant causes more infections and spreads faster than earlier forms of the virus that causes COVID-19.

  4. Currently, several variants of the virus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) are creating concern in the U.S. These variants include: Delta (B.1.617.2). This variant is now the most common COVID-19 variant in the U.S. It’s nearly twice as contagious as earlier variants and might cause more severe illness.

  5. Sep 22, 2021 · Current COVID-19 variants of concern spread more rapidly and some cause more severe illness. Rapid spread could lead to more cases, more deaths, and could overwhelm hospitals and healthcare resources. The more the COVID-19 virus circulates, the greater the chances that new mutations or variants can develop.

    Multiple variants of the virus that causes COVID-19 have been identified globally during the COVID-19 pandemic. Variants are determined by their genetic sequences. It's important to understand that genetic mutations of the virus that causes COVID-19, SARS-CoV-2, are expected, and that there are many strains of the virus. Public health, academic, and clinical partners are working together to sequence the genetic material of the virus in California. The term variants being monitored (VBM) is used to describe a variant for which there are data indicating a potential or clear impact on treatment or that has been associated with more severe disease or increased transmission but are no longer detected or are circulating at very low levels, and as such, do not pose a significant and imminent risk to public. The term variant of interest (VOI) is used to describe a newly emerging variant for which the medical and public health importance is not yet known. If a variant is thought to be more c...

    Multiple variants of the virus that causes COVID-19 have been identified globally during the COVID-19 pandemic. Variants are determined by their genetic sequences. It's important to understand that genetic mutations of the virus that causes COVID-19, SARS-CoV-2, are expected, and that there are many strains of the virus. Public health, academic, and clinical partners are working together to sequence the genetic material of the virus in California. The term variant of interest (VOI) is used to describe a newly emerging variant for which the medical and public health importance is not yet known. If a variant is thought to be more contagious or likely to cause greater illness or severe disease, or may impact treatment or vaccine response, then it is considered a variant of concern (VOC).

    Scientists and public health officials are studying variants to learn more about how to control their spread. They want to understand whether the variants: 1. Spread more easily from person-to-person 2. Cause milder or more severe disease in people 3. Are detected by currently available viral tests 4. Respond to medicines currently being used to treat people for COVID-19 5. Change the effectiveness of COVID-19 vaccines

    CDPH collects data on variant sequences from a variety of different sources to assemble a picture of the different strains currently circulating in California. The variant strains shown in the tables below are those CDC has designated a variant being monitored or a variant of concern of interest. CDC maintains alisting of these variants and displays the prevalence of the variants of concern circulating in the United States by state.

    CDPH is working with federal, local and academic partners to better understand how variants might impact Californians, including if they have any differences in their response to vaccination. The immune response resulting from either COVID-19 infection or vaccine targets several parts of the SARS-CoV-2 spike protein. Even if a virus has one or more mutations in the spike protein, vaccines and natural infection would still be expected to provide valuable protection.

    B.1.1.7 (Alpha) variants are associated with approximately 50% increased transmission, and likely with increased disease severity and risk of death. Appears to have minimal impact on the effectiven...
    B.1.351 (Beta) variants are associated with approximately 50% increased transmission. May have moderately decreased response to antibody treatments.
    P.1 (Gamma) variants may have moderately decreased response to some antibody treatments.

    B.1.617.2 (Delta) variants are associated with approximately 200% increased transmission. May have moderately decreased response to antibody treatments. (Delta totals include all Delta AY sublineag...

    As of September 22nd 167,468 samples have been sequenced in California. In August 2021, 9% of cases in California were sequenced, and this percent is expected to increase in coming weeks as more data becomes available. In July 2021, 16% of cases in California were sequenced. This is the number of sequences submitted to the data repository GISAID and is not a complete list of sequences completed to date. Variantsbeing monitored by CDPH are shown in the table below. CDC and CDPH do notconsider them variants of concern at this time.

  7. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), has many variants; some are believed, or have been believed, to be of particular importance due to their potential for increased transmissibility, increased virulence, or reduced effectiveness of vaccines against them.
