Health through Walls (HtW) is a not for profit organization registered in the state of Florida in the United States. HtW works in partnership with correctional administrations and health care staff of developing countries to assist their efforts in delivering effective and quality health care in their prisons. HtW works to implement sustainable and replicable models in the delivery of prisoner health care. Our primary focus is the identification, prevention, and management of infectious disease, especially HIV/AIDS and tuberculosis.

Several of these systems are severely overcrowded, have a high burden of disease, and lack sufficient resources. The work of HtW involves providing direct patient care services to prisoners, technical assistance, staff training, medicine, policy review, resource collection and donation, establishing laboratory services for the diagnosis of tuberculosis, HIV testing, conducting needs assessments, providing resources, training nursing staff in health assessments, intervening to lessen the effects of beriberi and malnutrition in the prisons, facilitating meetings between stakeholders, and providing equipment and supplies to facilitate improved health care delivery, developing systems of disease screening and medical triage, securing educational and material resources, and building alliances with community organizations.

HtW works with all stakeholders to find solutions to the health needs of prisoners. HtW advocates for community responses and resources to address the health issues for prisoners that ultimately impact public health. Since 2001, HtW has been providing services in Haiti's national prison and expanded to provide services in the prisons in Jamaica, the Dominican Republic, the African countries of Democratic Republic of Congo, Tanzania, South Africa, Malawi, Namibia, Mozambique, Kenya, Rwanda, and Ghana as well as in Romania in Europe.
