Our manuscript was based on surveillance cases of COVID-19 identified before January 26, 2020. As February 20, 2020, the total number confirmed in mainland China has reached 18 times our manuscript. While methods and main conclusions original analyses remain solid, we decided to withdraw this preprint for time being, will replace it with a more up-to-date version shortly.

Abstract Understanding the epidemic growth of novel SARS-CoV-2 Omicron variant is critical for public health. We compared ten-day secondary attack rate (SAR) and Delta variants in households using Norwegian contact tracing data, December 2021 - January 2022. SAR was higher than Delta, with a relative risk (RR) 1.41 (95% CI 1.27-1.56). observed increased susceptibility to infection household contacts independent contacts’ vaccination status. Among three-dose vaccinated contacts, mean lower...
Abstract Background As of April 2, 2020, the global reported number COVID-19 cases has crossed over 1 million with more than 55,000 deaths. The household transmissibility SARS-CoV-2, causative pathogen, remains elusive. Methods Based on a comprehensive contact-tracing dataset from Guangzhou, we estimated both population-level effective reproductive and individual-level secondary attack rate (SAR) in setting. We assessed age effects infectivity during their incubation period. Results A total...
Background The natural history of disease in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remained obscure during the early pandemic. Aim Our objective was to estimate epidemiological parameters (COVID-19) and assess relative infectivity incubation period. Methods We estimated distributions four SARS-CoV-2 transmission using a large database COVID-19 cases potential pairs cases, assessed their heterogeneity by demographics, epidemic phase geographical...
Abstract Understanding the rapid epidemic growth of novel SARS-CoV-2 Omicron variant is critical for public health management. We compared secondary attack rate (SAR) and Delta variants in households using Norwegian contact tracing data from December 2021 to January 2022. SAR was higher (51%) than (36%), with a relative risk (RR) 1.41 (95% CI 1.27–1.56). observed increased susceptibility infection household contacts independent vaccination status; however, considering booster vaccinated...
