Hepatitis 'B' is a disease spread through contact with infected bodily fluids. It can be transmitted through blood transfusions, use of unclean needles or sexual activity. Any travellers visiting a country known to have many carriers of the disease, where blood transfusions may not be adequately screened or where sexual contact is possible should consider a hepatitis B vaccination. The vaccination consists of three injections, with at least four weeks between the first and second shots, and five months between the second and third.
