Hepatitis C is generally referred to as viral hepatitis C. The ways of transmission include blood transmission, sexual transmission, and mother-to-child transmission. 1. Blood transmission: Viral hepatitis C is mainly transmitted through blood transfusion and transfusion of blood products. If patients with viral hepatitis C use non-disposable syringes or needles, as well as unsterilized endoscopes, dental instruments and other medical devices, it may or may not lead to hepatitis C virus transmission. In addition, sharing razors, toothbrushes, tattoo equipment, etc. with patients with viral hepatitis C may also lead to hepatitis C virus infection. 2. Sexual transmission: Hepatitis C virus can be detected in semen or vaginal secretion of viral hepatitis C. Sexual relationship with patients with viral hepatitis C may lead to infection of sexual partners. 3. Mother-to-child transmission: If a pregnant woman suffers from viral hepatitis C, she may transmit hepatitis C virus to her fetus during delivery. There are many ways of transmission of viral hepatitis C. It is suggested that we should do a good job of personal protection and avoid having sex with patients with viral hepatitis C or sharing personal products such as razors.
