Active and cumulative infected time series in the Balearic Islands. Time evolution of the average number of (A) active infected cases (black line) and (B) cumulative number of cases with the best-fitted parameters, and confidence interval CI 95% (gray area). Confidence intervals calculated using Cox's method (26). Red dots represent the data provided by the Ministry of Health of Spain, the solid lines depict the model with the fitted parameters T_lat = 2, T_inf = 4, T_dis = 12, β₁ = 0.24, β₂ = 0.12, β₃ = 0.016, β₄ = 0.036, β₅ = 0, the orange area represents the number of undetected cases when comparing model results with the data on detected cases.
