Prisoners have disproportionate health care needs. Meeting those needs in a prison environment is challenging, especially in such resource-poor countries as Haiti. Even so, before the January 2010 earthquake, local and international organizations, in collaboration with the Haitian government, had been making significant progress to provide for the health needs of prisoners. The effort screened and identified prisoners for infectious disease, initiated appropriate care and treatment, and prepared prisoners for release to the community. Not only is it possible to establish an adequate prison health care program in a resource-poor country, it is necessary. Without adequate management of prisoners' health needs, especially for such infectious diseases as HIV and tuberculosis, disease burden increases. Infectious disease can spread among prisoners and impact the public's health. Recovery for postearthquake Haiti, as any nation rebuilding following natural disaster or conflict, requires respect for rule of law. This includes humane detention and the delivery of justice and adequate health care for prisoners.
