摘要
In this paper, we propose a susceptible-exposed-infection-asymptomatic-hospitalized-recovered (SEIAHR) model with parameters on retrospective social distancing and masking. We estimated the model parameters from information published on the World Health Organization (WHO) website. We found that the actual reproduction number <em>R<sub>t</sub></em><sub> </sub>varies over the period from 03 March to 07 June 2020 and moreover, effective control over contacts and the frequency of population movement would reduce the evolution of the epidemic (control <em>c</em> <span style="white-space:nowrap;">≥</span> 50%). And the contact check has an influence on the base reproduction number <em>R</em><sub>0</sub>.
