Apr 4, 2024 · Like all viruses, COVID-19 has evolved and changed since it started in 2019. New variants (mutated versions) of the virus continue to emerge. COVID JN. 1 is currently the predominant U.S. variant ...
Feb 6, 2023 · CDC uses viral genomic surveillance to quickly identify and track COVID-19 variants, and acts upon these findings to protect the public’s health. Some variants spread more easily and quickly than others, which may lead to more cases of COVID-19. For the most up to date information about current variants, visit CDC’s COVID Data Tracker.

By the end of 2020, the original L strain of the COVID virus had gone through multiple mutations, including the S, V, and G strains. The first highly publicized variant—B.1.1.7, then called Alpha—showed up in the United Kingdom in September 2020. Alpha caused a surge of COVID infections around the world, starting before any vaccines were available....
Shortly after Alpha was discovered, the Beta variant of the COVID virus (B.1.351) was identified in South Africa. It quickly spread to other countries. An estimate cited by the Centers for Disease Control and Prevention (CDC) suggested that the Beta variant was about 50% more transmissible than the original strain of the COVID virus, it only ever a...
P.1, the Gamma variant of the COVID virus, was first identified in Brazil in November 2020. Gamma was not responsible for many COVID cases in the U.S. In the fall of 2021, the CDC noted that there appeared to be a risk for “breakthrough” COVID infections in people who had been fully vaccinated. Although data on the Gamma variant was limited, expert...
In July 2020, researchers identified a new variant in Southern California. The WHO called it Epsilon, and it included B.1.427 and B.1.429. By the fall, experts considered it one of the variants to monitor. The main concern with the Epsilon variant was that the mutations in the spike protein would make it able to get around the antibodies people had...
B.1.617.1 was dubbed the Kappavariant. It was first detected in India in the fall of 2020. It spread to other countries and the WHO considered it a Variant Under Investigation. However, global public health experts did not consider it to be a major variant of concern. As of fall 2021, the WHO deemed it a variant to monitor. Most of the reported cas...
C.37 was called the Lambda variant. It was first identified in Peru in December 2020.It spread to other countries, including the U.S., but did not account for as many cases as other circulating variants. As with other new strains, the main concernswere that the Lambda variant would spread more easily, cause more severe illness, and resist vaccines ...
B.1.525, the Eta variant, was first detectedin the UK and Nigeria in December 2020. It did not account for as many cases as other circulating variants, and researchers were not sure what the implications of the changes in the virus would be in terms of transmissibility and immunity.
B.1.621/B.1.621.1, or the Mu variant, was identified in Colombia in January 2021 and deemed a variant of interest by the WHO in late summer. Outbreaks related to Mu were mostly in South America and Europe, though it eventually spread to other countries including the U.S.
B.1.526, called the Iota variant, was first identified in NYC in February 2021.The main concern with this variant was that it was spreading more easily and making people a lot sicker, carrying a higher COVID mortality rate than other variants.
P.2, the Zeta variant, was identified in Brazil in February 2021.It was a variant of interest, but not a variant of concern. When it did not spread further, the WHO dropped the variant of interest designation.

Sep 1, 2023 · It’s estimated that Delta caused more than twice as many infections as previous variants—in Connecticut, it was estimated to have been 80 to 90% more transmissible than the Alpha variant. In the U.S., in June 2021, after a steady decline in COVID-19 cases and hospitalizations, the arrival of Delta coincided with a rapid reversal of that trend.
