The interaction of severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) and the renin angiotensin system (RAS) via angiotensin converting enzyme-2 (ACE-2), the receptor used by the SARS-CoV-2 to gain access to cells could provide an explanation for the several unusual clinical findings observed in COVID-19 Although chronic hepatitis is one of the risk factors listed by WHO for severe COVID-19, low incidence of COVID-19 was observed among HCV patients admitted to Egyptian hospitals.~Modulation of the RAS by the chronic hepatitis C virus treatment either by (ACEI or ARBS), (Daclatasvir and Sofosbuvir), (Daclatasvir and Sofosbuvir plus Ribavirin), or (Ribavirin and Interferon) protocols could give an explanation for the low incidence of COVID-19 among Egyptian population. Adding it may play a role in COVID 19 prophylaxis.
