A metastudy published in JAMA Network Open finds that the incubation periods for the Alpha, Beta, Delta, and Omicron variants were 5.00, 4.50, 4.41, and 3.42 days, respectively (with a pooled average of 6.57); Dr. Gregory Poland of the Mayo Clinic notes that if the Omicron variant had appeared first in 2020, “...we wouldn’t be talking about 1 out of 308 Americans being dead, we would probably be talking about 1 out of 200.”
