Detailed explanation-1: -Hepatitis B is spread when blood, semen, or other body fluids from a person infected with the virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth.

Detailed explanation-2: -People who inject drugs can get Hepatitis C from: Needles & Syringes. Sharing or reusing needles and syringes increases the chance of spreading the Hepatitis C virus. Syringes with detachable needles increase this risk even more because they can retain more blood after they are used than syringes with fixed-needles.

Detailed explanation-3: -Hepatitis B is spread through sexual contact (homosexual and heterosexual), needle sharing, needle stick injury, mucous membrane exposure, and direct contact with infected body fluids. There appears to be no transmission of Hepatitis B via tears, sweat, urine, and stool or droplet nuclei (airborne).

Detailed explanation-4: -Yes. Hepatitis B is easily transmitted through sexual activity. In fact, sexual contact is the most common way Hepatitis B is spread in the United States. Hepatitis B is 50-100 times more infectious than HIV.
