Viral hepatitis is divided into five types: A, B, C, D, and E. Among them, hepatitis A and hepatitis E are transmitted through the digestive tract, that is, transmitted by unclean diet. The main clinical manifestations are weakness, nausea, aversion to grease, loss of appetite, and even yellow urine, body and eyes, which are usually acute hepatitis, and they are well after 1-3 months, and can be fully recovered within six months. In contrast, hepatitis B, C and D are mainly transmitted through blood and can be acute or chronic, requiring long-term monitoring and standardized treatment. There is no chronicity or recurrence of hepatitis A and hepatitis E, which means that you will not get hepatitis A again after you have gotten well from hepatitis A. However, because there is no cross-immunity between the various types of viral hepatitis, there is a possibility of getting other types of hepatitis such as hepatitis E and hepatitis B. Therefore, even if you have had hepatitis, you still need to be hygienic to prevent the occurrence of other types of hepatitis.
