Among these cases of COVID-19 attributed to the Omicron variant, 34 (79%) occurred inpersons whocompleted the primary series of an FDA-authorized or approved COVID-19 vaccine 14 days before symptom onset or receipt of a positive SARS-CoV-2 test result, including 14 who had received an additional or booster dose; five of the 14 persons had received the additional dose <14 days before symptom onset. Other transmission settings included conversations in the home, a building or car, or outdoors. doi:10.1016/S2214-109X(21)00593-3, Belay ED, Abrams J, Oster ME, et al. We calculated the incubation period by using the calendar dates of contact and symptom onset, regardless of duration or number of contacts. Even if most infections are mild, a highly transmissible variant could result in enough cases to overwhelm health systems.

The mean virus incubation period during the SARS-CoV-2 Omicron BA.5-dominant period in Japan was 2.6 (95% CI 2.5-2.8) days, which was less than during the Delta-dominant period. (1) A study conducted during high levels of Delta variant transmission reported an incubation period of 4.3 days, (2) and studies performed during high levels of Omicron variant transmission reported a median incubation period of 3-4 days. We defined patients in the BA.1dominant period as those who had symptom onset during January 1February 2, 2022. A shorter incubation suggests a shorter quarantine period for BA.5 than for other variants. On 26 November 2021, WHO designated the variant B.1.1.529 a variant of concern, named Omicron, on the advice of WHO's Technical Advisory Group on Virus Evolution (TAG-VE).
