“…Therefore, the Quarantined Recovered (Q-R) state is introduced with the same connections to R as the connections between S and Q-U. Though the reinfection rate of SARS-CoV-2 has been a point of recent debate, it is assumed that the number of re-infected individuals is small (30)(31)(32)(33)(34). Therefore, individuals cannot transition from R to S, hence the separately categorized quarantined populations.…”

“…Furthermore, this study is a single-center, retrospective study with limited participants, therefore, more prospective clinical researches are needed. Some researchers hypothesized that the re-positive cases could be a virus re-infection [13]. Immunologically speaking, after the acute infection of the SARS-CoV-2, the human body could generate specific neutralizing antibodies against this virus for at least 7 days [14]; furthermore a recent animal experiment in rhesus macaque indicated re-infection phenomenon would not happen [15].…”

“…For instance, it has been reported that the coronavirus can still be detected in throat swabs from recovered patients up to 13 days after they present no symptoms of the disease (as evaluated by clinical assessments), indicating that even people considered to be recovered from Covid-19 may still potentially infect others [ 19 ]. Furthermore, it has been speculated the possibility of reinfection for patients who recovered from Covid-19 (in this regard, preliminary data from primates support the hypothesis of immunization and protection against reinfection [ 20 ]). In fact, we are aware that the model does not cover extensively the possible complexities related to disease propagation, but it focuses on the main course of propagation instead.…”
