TL;DR: Influenza transmission declined substantially after the implementation of social distancing measures and changes in population behaviours in late January, with a 44% (95% CI 34–53%) reduction in transmissibility in the community.
Journal ArticleDOI
Clustering and superspreading potential of SARS-CoV-2 infections in Hong Kong.
Dillon C Adam,Dillon C Adam,Peng Wu,Jessica Y. Wong,Eric H. Y. Lau,Tim K. Tsang,Simon Cauchemez,Gabriel M. Leung,Benjamin J. Cowling +8 more
TL;DR: Cases linked to superspreading events are estimated to account for 80% of all local transmission of SARS-CoV-2 in Hong Kong in a study with implications for public health policies.
Journal ArticleDOI
Comparative epidemiology of human infections with avian influenza A H7N9 and H5N1 viruses in China: a population-based study of laboratory-confirmed cases

TL;DR: The sex ratios in urban compared with rural cases are consistent with exposure to poultry driving the risk of infection--a higher risk in men was only recorded in urban areas but not in rural areas, and the increased risk for men was of a similar magnitude for H7N9 and H5N1.
Journal ArticleDOI
Human infection with avian influenza A H7N9 virus: an assessment of clinical severity
Hongjie Yu,Benjamin J. Cowling,Luzhao Feng,Eric H. Y. Lau,Qiaohong Liao,Tim K. Tsang,Zhibin Peng,Peng Wu,Fengfeng Liu,Vicky J. Fang,Honglong Zhang,Ming Li,Lingjia Zeng,Zhen Xu,Zhongjie Li,Huiming Luo,Qun Li,Zijian Feng,Bin Cao,Weizhong Yang,Joseph T. Wu,Yu Wang,Gabriel M. Leung +22 more
TL;DR: The clinical severity of human infections with avian influenza A H7N9 virus, which emerged in China in early 2013, seems to be less serious than has been previously reported.
Journal ArticleDOI
Effect of changing case definitions for COVID-19 on the epidemic curve and transmission parameters in mainland China: a modelling study.
TL;DR: Whether changes in case definitions affected inferences on the transmission dynamics of coronavirus disease 2019 (COVID-19) in China and how the epidemic curve would have appeared if the same case definition had been used throughout the epidemic is assessed.
