What makes the Omicron variant different from the original strain of COVID-19? | UCHealth

Dr. Michelle Barron, senior medical director of infection prevention and control for UCHealth, gives us insight into how the variants differ from the original strain of COVID-19 and what you can expect if you get them. She says the ancestral strain of COVID-19 was considered a “marathoner”, which means it took much longer for the viral load to build up and have an effect. For example, you could be exposed but not see any symptoms until 10 days later. Variants of COVID-19, including the Omicron variant, seem to be “sprinters”, which means the viral load is delivered much faster, but also goes away quicker.
