Engaging Communities Affected by Hepatitis B

The impact of chronic hepatitis B infection on the health care system is increasing. To effectively reduce this burden, the health care system needs to understand how people and the communities most affected respond. Through talking with people with chronic hepatitis B and health workers, the National Hepatitis B Needs Assessment highlights significant gaps in the health care system response to chronic hepatitis B. This article highlights some of these gaps, including poor diagnostic processes, lack of information available about chronic hepatitis B for people who are infected, the need for workforce development (particularly for health and community workers involved with communities most at risk) and issues relating to access to treatment for chronic hepatitis B. The Australian health care system needs to develop effective coordinated responses to chronic hepatitis B before its burden can be reduced.
