Of roughly 2 million infections reported in Denmark from November to February, researchers focused on patients who tested positive twice from 20 to 60 days apart, and experienced infections previously labeled a subvariant by genomic surveillance. Protection given by past infection is around 5.4 times less effective against Omicron than it was against Delta, a UK study found. That means from a starting point of 100 positive infections you'd expect around 1,000 people to have died within 60 days.

While it is milder, it can infect people more quickly and in rare cases come back around for a second hit. BA.2 is similar to BA.1, but has 20 different mutation. Amiji adds that as vaccines continue to aid an ever-expanding amount of the population in blocking potential viral infections, it makes sense that SARS-CoV-2 strains will likely continue to mutate in response. Omicron, and it's sub-variant BA.2, are quicker at spreading and can get around vaccine immunity a bit better.

Gluckstein explained this is why Omicron caused a dramatic wave of recent infections, but a less dramatic increase in severe disease and death than earlier COVID-19 variant strains. Like all virus variants, Omicron comprises several lineages and sub-lineages.
