Title: | An extended weight kernel density estimation model forecasts COVID-19 onset risk and identifies spatiotemporal variations of lockdown effects in China | Authors: | Shi, W Tong, C Zhang, A Wang, B Shi, Z Yao, Y Jia, P |
Issue Date: | 2021 | Source: | Communications biology, 2021, v. 4, no. 1, 126 | Abstract: | It is important to forecast the risk of COVID-19 symptom onset and thereby evaluate how effectively the city lockdown measure could reduce this risk. This study is a first comprehensive, high-resolution investigation of spatiotemporal heterogeneities on the effect of the Wuhan lockdown on the risk of COVID-19 symptom onset in all 347 Chinese cities. An extended Weight Kernel Density Estimation model was developed to predict the COVID-19 onset risk under two scenarios (i.e., with and without the Wuhan lockdown). The Wuhan lockdown, compared with the scenario without lockdown implementation, in general, delayed the arrival of the COVID-19 onset risk peak for 1–2 days and lowered risk peak values among all cities. The decrease of the onset risk attributed to the lockdown was more than 8% in over 40% of Chinese cities, and up to 21.3% in some cities. Lockdown was the most effective in areas with medium risk before lockdown. | Publisher: | Nature Publishing Group | Journal: | Communications biology | EISSN: | 2399-3642 | DOI: | 10.1038/s42003-021-01677-2 | Rights: | © The Author(s) 2021, corrected publication 2021 This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
