Optimal control of HCV transmission under liquoring.

Chronic hepatitis C virus (HCV) and alcohol are common causes of chronic liver diseases and both are recognized as major causes of liver disease worldwide. Each poses a major public and economic burden to society, and when the two co-exist they appear to have a synergistic effect in the progression of chronic liver disease. In this research, we developed a SIRS model of transmission of the hepatitis C virus (HCV) under effect of liquoring in six compartments: Susceptible, Low liquoring, High liquoring, Acute, Chronic and Recovered Individuals.
