National Reproduction Number (R) Based on Reported Cases

Identifying changes in the reproduction number, rate of spread, and doubling time during the course of the COVID-19 outbreak whilst accounting for potential biases due to delays in case reporting both nationally and subnationally. These results are impacted by changes in testing effort, increases and decreases in testing effort will increase and decrease reproduction number estimates respectively.

本研究旨在明确新冠疫情（COVID-19 outbreak）暴发期间，传播再生数（reproduction number）、传播速率与倍增时间的动态变化，同时校正因国家级与次国家级层面病例报告延迟所引发的潜在偏倚。检测力度的变动会对上述结果产生影响：检测力度提升与降低，将分别导致传播再生数估计值的升高与降低。
