A rapid response to global infectious disease outbreaks is crucial to protect public health. Ex ante information on the spatial probability distribution of early infections can guide governments to better target protection efforts. We propo...
On the use of the reproduction number for SARS-CoV-2: Estimation, misinterpretations and relationships with other ecological measures [0.03%]
SARS-CoV-2的基本繁殖数的使用：估算、误读及其与其它生态学指标的关系
Nicholas P Jewell,Joseph A Lewnard
Nicholas P Jewell
The basic reproduction number, R 0, and its real-time analogue, Rt , are summary measures that reflect the ability of an infectious disease to spread through a population. Estimation methods for Rt have a long history, have been widely deve...
