What is a significant route of transmission for Hepatitis B?

Hepatitis B is primarily transmitted through blood and bodily fluids, which includes sexual intercourse and sharing needles. This mode of transmission is significant because the Hepatitis B virus (HBV) is highly infectious, and even small amounts of blood can carry the virus. Sexual transmission occurs through contact with infected bodily fluids, and blood-borne transmission is common in scenarios such as intravenous drug use or exposure to infected blood through cuts or abrasions.

The presence of HBV in bodily fluids means it can also be transmitted through other routes, such as perinatal transmission from mother to child during childbirth. However, the most significant and common routes remain the blood-borne and sexual avenues.

Understanding the transmission routes is crucial for implementing prevention strategies such as vaccinations, safe sex practices, and safe handling of blood products, all of which are essential in controlling the spread of Hepatitis B.
