In spite of efforts to treat the disease but there are many different cases of hepatitis type B and C. In the present study, we analyse data on the cases of hepatitis in Saudi Arabia, especially the Northern areas “Arar” and neighbouring cities and use this data to compare the prediction of disease models.
