Viral hepatitis mainly includes Hepatitis A, B, C, D, E, etc., among which Hepatitis A and E are acute infections. Generally, there is no long-term damage to the human body after infection; recovery of liver function suffices. Hepatitis B and C infections are prone to becoming chronic, leading to chronic hepatitis B and chronic hepatitis C, respectively. These chronic infections can easily lead to cirrhosis and liver cancer. Among them, the carrier rate of HBsAg in hepatitis B is about 7%, and there are approximately 9.6 million people with hepatitis C in China. Therefore, the incidence rates of hepatitis B and C are relatively high, and if there are abnormalities in liver function, it is crucial to check for these diseases.
