SARS-CoV-2 Variants and Genomic Surveillance in Texas. Variants of SARS-CoV-2, the virus that causes COVID-19, are expected to continue to emerge, a natural process that occurs as viruses spread. Some variants will disappear, and others will continue to spread and may overtake previous variants. For example, the ancestral strain of the virus ...
Oct 1, 2021 · While BA.2.86 has a significant number of mutations to the viral genome compared to other currently circulating COVID-19 variants, the data so far is too limited to draw firm conclusions about the ...
Aug 2, 2022 · Variety is the spice of life — except when it comes to viral infections like COVID-19, which is caused by the SARS-CoV-2 virus. The more that SARS-CoV-2 spreads, the greater the chance that its genetic material will change, or mutate, creating new variants or strains. The virus builds up mutations as it passes from person to person, possibly ...
Jan 9, 2024 · Vaccines, tests, and antivirals are still effective tools in the latest COVID surge. In early November 2023, the JN.1 variant caused less than 5% of COVID-19 cases in the U.S. Now it is estimated to cause more than 60% of them. Virologists including Andy Pekosz, PhD, a professor in Molecular Microbiology and Immunology, are paying attention.
Nov 26, 2021 · WHO will communicate new findings with Member States and to the public as needed. Based on the evidence presented indicative of a detrimental change in COVID-19 epidemiology, the TAG-VE has advised WHO that this variant should be designated as a VOC, and the WHO has designated B.1.1.529 as a VOC, named Omicron.
Apr 9, 2024 · What are variants of COVID-19? Viruses are constantly changing, including the virus that causes COVID-19. These changes occur over time and can lead to new strains of the virus or variants of COVID-19. Slowing the spread of the virus, by protecting yourself and others, can help slow new variants from developing. CDC is working with state and ...
Apr 26, 2024 · SARS-CoV-2 (the virus that causes COVID-19) evolves over time, which results in a new strain (variant) of the virus. With COVID-19, new variants continue to emerge, with some variants disappearing while others will persist. The SARS-CoV-2 variants are classified into four groups: new variants of concern, variants of high consequence, variants being monitored and variants of interest. The AMA ...
