Both HBV & HCV are blood born viruses, and can be transmitted through any blood to blood contact.
HBV is very contagious and can be transmitted sexually.
The following comes from HeptitisAustralia.
Hepatitis B is found in body fluids including blood, saliva, semen, mucus, vaginal fluid and breast milk. It can be easily transmitted through sexual activity, sharing injecting equipment, sharing toothbrushes or razors, unsterilised tattooing and body piercing equipment and from mother to child at birth.
Ways to reduce hepatitis B transmission are to:
wash hands after touching blood or body fluids
wear disposable gloves if giving someone first aid or cleaning up blood or body fluids
avoid sharing toothbrushes, razors, needles, syringes, personal hygiene items and grooming aids or any object that may come into contact with blood or body fluids
use new and sterile injecting equipment for each injection
cover all cuts and open sores with a bandage
wipe up any blood spills and then clean the area with household bleach
throw away personal items such as tissues, menstrual pads, tampons and bandages in a sealed plastic bag
practice safe sex
People who think they have been exposed to hepatitis B and who have not been vaccinated should receive hepatitis B immunoglobulin (HBIG) within 14 days of exposure from their general practitioner.
Awfully similar to the documented ways of catching HepC ay.
This is a hepatitis forum however the majority of people here have HepC. There are a few with HepB.
Hopefully they will reply. If not you can google HepB and I m sure you can get all your answers.
HepB is transmitted sexually.
I heard it's very contagious. You can get it from sex, saliva and other ways also. This is a hep. C forum we don't know much about hep.B.
