Variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are viruses that, while similar to the original, have genetic changes that are of enough significance to lead virologists to label them separately. SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19).
As of 6 January 2022, Omicron multiplied around 70 times faster than the Delta variant in the bronchi (lung airways) but evidence suggested it is less severe than previous variants, especially compared to Delta, [276] [236] since it might be less able to penetrate []

Staphylococcus aureus delta toxin is a phenol-soluble modulin peptide. Because of this, the cytotoxins that are produced upon a S. aureus infection, including delta toxin, are proinflammatory molecules. Delta toxin is also a chemoattractant for leukocytes [5]
Lineage B.1.617 is a lineage of SARS-CoV-2, the virus that causes COVID-19. [ 1] It first came to international attention in late March 2021 after the newly established INSACOG performed genome sequencing on positive samples throughout various Indian states.
Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal.
