Patient's question:
Is hepatitis B a contagious disease? Generally, how is it infected through life?Doctor's answer:
Medical history introduction: Hepatitis B is a contagious disease. The hepatitis B virus (HBV) can be transmitted through various body fluids such as blood, semen, and milk. It then infects susceptible individuals through the following routes:1. Blood or blood products, contaminated needles, surgical instruments, especially during surgery and blood transfusions, can allow the hepatitis B virus to enter the body.
2. Perinatal transmission: If a mother is infected with the hepatitis B virus, especially when she is HBeAg (+) and HBV-DNA (+), the infant is very likely to be infected.
3. Sexual contact can also spread hepatitis B, but it is never spread through the respiratory tract.
Since the condition of each patient is different, the treatment methods will also vary. Therefore, patients need to undergo timely examination and diagnosis to receive appropriate treatment.
