How is hepatitis b contracted and spread?

I was reading about this because of a college project. It spreads when blood or body fluids from an infected person enter someone who is not infected, like through shared needles or intimate contact.

My family was worried it spreads like cold, but our doctor explained it only spreads through contact with infected blood and fluids. It's very important to ask your doctor about the vaccine, which is the best protection.

Hepatitis B is contracted through contact with infectious blood, semen, and other body fluids.

I have managed Hepatitis B for years. It spreads through blood-to-blood contact, so make sure your barber always uses a fresh blade. Also, ensure your family members get vaccinated, as it's the safest shield.

Hey, it basically spreads through infected needles, tattoos with unsterilized equipment, or unprotected sex. It doesn't spread through casual contact like shaking hands, so no need to freak out.

It is spread through blood, and because I got it from an unsafe injection years ago, my liver suffered a lot. Please, if you have any doubt of exposure, consult a doctor immediately and get tested.
