Abstract

Given the heterogeneity in individual transmissibility, we estimated the superspreading potential of SARS-CoV-2 Delta variants. Using case series of Delta variants in Guangdong, China, we found 15% (95%CrI: 12, 19) of cases seeded 80% of offspring cases.

Keywords: COVID-19; China; Delta variant; statistical modelling; superspreading.
