Are some people more at risk than others of hepatitis B?

Because hepatitis B is transmitted through blood and body fluids, and especially during sexual intercourse, those most at risk are heterosexual women and gay men who have had many sexual partners, addicts who use intravenous drugs, people who have been tattooed with dirty needles and health professionals who may come into contact with the blood of an infected person. It is important to remember that anyone who falls into any of these groups can be vaccinated.
