Analysis of the Transmissibility Change of 2019-Novel Coronavirus Pneumonia and Its Potential Factors in China from 2019 to 2020

- An index based on the search volume where keywords are used as statistical objects. A weighted sum of the frequency of each keyword in the Baidu web search is calculated as BDI. For the purposes of this study, the keywords “new coronavirus” was used to measure the BDI.

- A scale that reflects the size of migration or emigration in one place in China. Wuhan was selected as emigration destination.
- The daily BMS was calculated daily from Jan. 1, 2020 to Feb. 9, 2020.
