Prevention
There is no specific vaccine for hepatitis D. Vaccination against hepatitis B will prevent hepatitis D infection although it cannot prevent superinfection. This means that if you already have hepatitis B you cannot prevent infection with hepatitis D.
If you suspect or know you have an infection you must reduce the risk of infecting others. It
important that you:
-
clean and cover your cuts, scratches and open wounds with a waterproof plaster
-
clean up blood from floors and work surfaces with undiluted household bleach
-
do not use anyone else’s toothbrush, razor, scissors or other personal items
-
ensure drug injecting equipment is sterile and not share it
practice safer sex by using a condom in all circumstances.
Do not donate blood or semen or register as an organ donor. There is also no current vaccine for hepatitis E. Because of this it is sensible to take precautions when you travel to endemic areas or areas where the virus is known to occur.
You are advised to avoid:
-
drinking tap water
-
having ice cubes in your drinks
-
drinking unpasteurised milk
-
eating uncooked shellfish
-
eating unpeeled fruit and uncooked vegetables that have not been prepared by you.
Always wash your hands properly after using the bathroom and before preparing and eating food.
