In this study, the authors compare the transmission dynamics of the Delta and Omicron SARS-CoV-2 variants using household data from Denmark. They find that Omicron has a higher secondary attack rate, and that the odds of infection with Omicron was higher than with Delta, particularly for vaccinated individuals.
