These small differences, or variants, have been studied and identified since the beginning of the pandemic. Currently, the Centers for Disease Control and Prevention (CDC) has identified one variant of the virus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) as a variant of concern: Omicron.

First came the alpha variant, first detected in the United Kingdom, that was more transmissible and caused the surges . In order for scientists to determine whether it's omicron or another coronavirus variant, the CDC uses genomic sequencing. The World . For the delta variant, the part of the spike protein that attaches to our cells is very similar to what existing coronavirus vaccines are designed to go after. CDC uses viral genomic surveillance to quickly identify and track COVID-19 variants, and acts upon these findings to protect the publics health. There are currently more than 34,679 cases reported in the United States per day, with test positivity of 10%.

As of February 18, 2023, XBB.1.5, also called kraken, is the dominant variant in Nebraska, making up 44% of cases. Sequencing can only be done at specialized labs. More data is needed to understand XBB, but early evidence suggests the risk of . There is some preliminary evidence suggesting the omicron variant is more infectious than the delta variant, says Bollinger. Data has suggested that the original Omicron strain was less severe, in general, than previous variants, according to the CDC. Some variants spread more easily and quickly than others, which may lead to more cases of COVID-19. Image: NIAID-RML via AP.
