A spatial-temporal analysis is presented to illuminate possible associations between the number of exposure-related COVID-19 cases in Singapore, and changes in human activity patterns before and during Singapore's Circuit Breaker; exposure-related COVID-19 cases exclude imported cases as well as cases in worker dormitories isolated from the community at large.
Specifically, changes in the usage of residential car parks ("mobility") across Singapore from 15 Mar to 28 Apr 2020 were analysed to provide a proxy of human activity patterns, and then modelled with the number of exposure-related COVID-19 cases. In addition, the transportation-related air emissions were estimated to analyse the impact of CB on environmental health.
