Hepatitis C, also known as hepatitis C, is mainly transmitted through blood or body fluids, including blood transmission, sexual transmission and close contact in daily life, and mother-to-child transmission. 1. Blood transmission: blood transfusion and blood products used to be the most important way of transmission of hepatitis C. For example, blood donors carrying hepatitis C virus may be infected with hepatitis C if their blood and blood products are imported, but now, due to the improvement of screening technology, the transmission of hepatitis C through blood transfusion has been greatly reduced. Injections, needles, hemodialysis, etc. have become invisible ways of blood transmission, especially for organ transplantation, bone marrow transplantation of people with low immunity are more susceptible to infection. 2. Sexual transmission and close contact in daily life: sexual contact can transmit hepatitis C virus through body fluids or blood, especially multiple sexual partners or homosexuals are high-risk groups. 3. Mother-to-child transmission: Hepatitis C-positive mothers are prone to transmit the hepatitis C virus during labor and delivery, leading to hepatitis C infection in newborns. Currently, there are drugs to eradicate this virus infection, such as interferon and ribavirin, etc. People infected with hepatitis C should seek medical treatment in time.
