In this study, the amount of SARS-CoV-2 exhaled by Omicron and Delta patients was compared. Our findings may help to explain why the Omicron variant is more transmissibility than the Delta variant. The Omicron SARS-CoV-2 variant (B.1.1.529) was first reported by the World Health Organization (WHO) from South Africa on 24 November 2021 ( https://www.who.int/news/item/26 -11 -2021-classification-of-omicron-(b.1.1.529)-sars-cov-2-variant-ofconcern ). The Delta variant began decreasing, whereas the Omicron variant continued its increase. The Omicron variant has replaced
