Hepatitis C is a viral hepatitis caused by hepatitis C virus (HCV) infection and is transmitted through blood, mother-to-child and sexual transmission. Patients who suspect they have hepatitis C need to be tested for hepatitis C antibodies, hepatitis C virus RNA, liver function, ultrasound, and hepatitis C genotyping. For screening for hepatitis C, the first test should be for hepatitis C antibodies. If the hepatitis C antibody is positive, further testing for hepatitis C virus RNA, which is a direct marker of hepatitis C virus replication and infection, is needed to confirm the diagnosis of hepatitis C infection. If the patient is diagnosed with hepatitis C infection, additional tests will be needed to evaluate the specific condition. First, liver function tests should be performed to understand the severity of liver damage. Next, a liver ultrasound should be performed to determine if hepatitis C has developed liver fibrosis and cirrhosis. Finally, hepatitis C genotyping should be checked and the results reported will help the doctor to select antiviral drugs for the patient. After the above mentioned tests, the patient’s condition can basically be evaluated initially, which can help in further treatment. In daily life, patients with hepatitis C should develop good hygiene habits, pay attention to personal hygiene, avoid sharing toothbrushes, towels, razors and hygiene products, etc. to avoid infection. Patients should try to use condoms when having sex to reduce the risk of sexual transmission. In addition, it is necessary to avoid blood contact with others as much as possible, and if there is a break in the skin, it should be bandaged in time to avoid infection due to blood.
