Together we can make a difference: the case for transnational action for improved health in prisons.

In spite of international differences in the treatment of incarcerated persons, as a group, they are vulnerable to poor health status and lack of access to quality health care. The health care of prisoners is affected by knowledge and commitment to ideas of human rights and social justice, as well as economic conditions. Prisoners are at increased risk of both acute and chronic diseases, and may constitute a threat to the health of other prisoners, their attendants or outside communities upon release. Mental illness and related problems of substance abuse are prevalent in prison populations, with many US prisons serving as modern asylums. Public health workers and organizations can stimulate and implement action to improve health in prisons. The World Federation of Public Health Associations can play a leadership role in co-ordinating and facilitating collaborative international action and research to enhance the health of prisoners and their communities worldwide.
