Since the start of the COVID-19 pandemic, the SARS-CoV-2 coronavirus that causes COVID-19 has mutated or (changed) resulting in different variants of the virus 
Previously, the Delta variant of SARS-CoV-2 discovered in India was considered the most dangerous variant because it spreads faster and causes more infections than previous versions of SARS-CoV-2, In fact, the novel coronavirus's Delta variant is thought to be twice as infectious as other variants. In 2021, Delta quickly became the dominant variant of the SARS-CoV-2 virus in the United States.
Scientists have discovered a new coronavirus variant known as omicron, which is more dangerous than the delta variant. However, they still lack specific information about omicorns.
