An epidemic model is presented to provide theoretical considerations for effective remediation of infected individuals. Water-drinking is feasible to curing of viral infection, especially as no effective medication is available. The best strategy is to limit food ingestion and increase fluid intake, since decreased ingestion reduces augmentation of susceptible components to be infected. Moreover, continuous fluid intake attenuates and washes out infected components in infected individuals. In contrast, the worst is to increase food ingestion and decrease water intake, as augmentation of susceptible components and persistence of infected component enhance ”chronic” disease transmission of viral infection.
