    Snippet: There are two enhanced features in our model in comparison to popular SEIR models [6] [8] [12] . The first one is a straightforward relationship between Exposed and Recovered population. We find that in the early outbreaks of COVID-19, some portion of exposed people may have no obvious symptoms or only develop as mild cases, but they cannot get a test due to lack of testing kits. This group of populations might be self-recovered in some days, but.....
    Document: There are two enhanced features in our model in comparison to popular SEIR models [6] [8] [12] . The first one is a straightforward relationship between Exposed and Recovered population. We find that in the early outbreaks of COVID-19, some portion of exposed people may have no obvious symptoms or only develop as mild cases, but they cannot get a test due to lack of testing kits. This group of populations might be self-recovered in some days, but will not realize they were infected. The second feature in our model is that we separate infectious population into mild and critical cases in light of their symptoms. It mainly concerns a phenomena of relatively higher mortality rate in the early outbreak of COVID-19 in Wuhan after taking immediate suppression intervention on 23 rd Jan 2020. Most likely, suppression intervention has led to fear in Wuhan citizens and chaos in hospital systems, as a result of delaying rescue of many critical cases.
