Patient's question:
This year during my health check-up, I carefully discovered that I had hepatitis B virus, but I didn't feel any discomfort. I didn't have any similar symptoms before, and I don't often catch colds either. So I want to know what causes the hepatitis B virus?Doctor's answer:
Hepatitis B, also known as HBV, is a disease caused by the hepatitis B virus infecting the body. The hepatitis B virus is a hepatotropic virus that primarily resides within liver cells and damages them, leading to liver cell inflammation, suppuration, and fibrosis. Hepatitis B is a blood-borne infectious disease, primarily transmitted through blood (such as unsafe injection histories), mother-to-child transmission, and sexual transmission. Skin and mucous membrane abrasion transmission also accounts for a certain proportion, such as tattoos, ear piercing, and endoscopic examinations. Blood products are now strictly controlled, significantly reducing the transmission risk. It may occur only during unregulated surgical procedures and blood product use.
