What is the primary mode of transmission for Hepatitis B?

The primary mode of transmission for Hepatitis B is through direct contact with infected blood. This bloodborne virus can be transmitted via several routes, including sexual contact, sharing of needles among intravenous drug users, and from an infected mother to her baby during childbirth. Hepatitis B is not transmitted through the air, food, or water; therefore, options relating to airborne, foodborne, and waterborne routes do not apply. Understanding that Hepatitis B is primarily a bloodborne pathogen highlights the importance of preventive measures such as vaccination, safe handling of blood products, and use of protection during sexual activity.
