Sensitivity analysis of parameters related to contact. a–d Sensitivity analysis of effective contact rate between people; e–h sensitivity analysis of effective contact rate between people and environment; i–l sensitivity analysis of the number of close contacts per infected person. We simulated the incidence, cumulative cases, and prevalence over time and the hospitalized cases when the three parameters increased by 50% and decreased by 50%, and compared them with the baseline levels. The sensitivity analysis curves of the corresponding parameters in figure e, f, g, i, j, k basically overlap
