One caveat, Pekosz notes, is that the level of testing has decreased, and fewer cases are being sequenced compared to even just a year ago. This certainly supports a study by the Centers for Disease Control and Prevention (CDC) which found that it took just three 3 days for people to show symptoms after being infected with Omicron.
