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.

本研究旨在识别新冠疫情暴发期间，再生数（reproduction number）、传播速率以及倍增时间的动态变化，同时兼顾国家与地方层面病例报告延迟所引发的潜在偏倚。此类结果会受到检测力度变化的影响：检测力度提升将使再生数估计值升高，反之则会使其降低。
