(A)Average predictions [Simple average of Mean Absolute Errors (MAE)] over all forecasts of the three 2-strain models and their different combinations for the Riyadh province.

(B)Estimated values of the Basic reproduction number (R0), the Hospital reproduction number (RH), and the Community reproduction number (RC)for the three provinces of Saudi Arabia using best model (two strain). The best two strain MERS model is with saturated incidence. The data are given as Mean (95% CI). *The MAE for the three models and their combinations during point prediction of peak week and peak incidence were calculated up-to the peak of the prediction season (11th Week) of the Riyadh province.
