Applying a New Framework for Public Health Systems Recovery following Emergencies and Disasters: The Example of Haiti following a Major Earthquake and Cholera Outbreak.

Emergencies can often directly impact health systems of an affected region or country, especially in resource-constrained areas. Health system recovery following an emergency is a complex and dynamic process. Health system recovery efforts have often been structured around the World Health Organization's health systems building blocks as demonstrated by the Post-Disaster Needs Assessment. Although this structure is valuable and well known, it can overlook the intricacies of public health systems. We retrospectively examine public health systems recovery, a subset of the larger health system, following the 2010 Haiti earthquake and cholera outbreak, through the lens of the 10 essential public health services. This framework illustrates the comprehensive nature of and helps categorize the activities necessary for a well-functioning public health system and can complement other assessments. Outlining the features of a public health system for recovery in structured manner can also help lay the foundation for sustainable long-term development leading to a more robust and resilient health system.

Development of Haiti's rural water, sanitation and hygiene workforce.

In 2009 the Haitian Directorate of Potable Water and Sanitation (DINEPA) identified an inadequately trained and under-staffed rural workforce as one of their main institutional challenges. Plans to address this challenge were impacted by the devastating earthquake of January 12, 2010 and the cholera outbreak of October 2010, both of which further complicated Haiti's already poor water and sanitation conditions. Recognizing the importance of DINEPA's institutional priorities, donor and technical assistance groups provided needed support to improve the country's conditions and build the rural water and sanitation workforce. This report describes how DINEPA and the US Centers for Disease Control and Prevention (CDC) collaborated to design and implement a training program for 264 potable water and sanitation technicians for rural areas. The paper also describes the initial field activities of the newly trained technicians and the immediate impact of their work in the rural water, sanitation and hygiene sector.

Water, sanitation and hygiene in Haiti: past, present, and future.

Haiti has the lowest rates of access to improved water and sanitation infrastructure in the western hemisphere. This situation was likely exacerbated by the earthquake in 2010 and also contributed to the rapid spread of the cholera epidemic that started later that same year. This report examines the history of the water, sanitation, and hygiene (WASH) sector in Haiti, considering some factors that have influenced WASH conditions in the country. We then discuss the situation sine the earthquake and subsequent cholera epidemic, and the responses to those events. Finally, drawing on Haiti's National Plan of Action for the Elimination of Cholera in Haiti 2013-2022, we suggest some actions that could help bring about long-term WASH improvements for the future. Because the current WASH situation has evolved over decades of limited attention and resources, it will take a long-term, sustained effort to improve the situation.

A community demand-driven approach toward sustainable water and sanitation infrastructure development.

In September 2001, Cooperative Assistance and Relief Everywhere, Peru Country Office (CARE Peru), obtained funding from the United States Agency for International Development (USAID) to implement community-supported, condominial water and sanitation interventions in Manuel Cardozo Dávila, a settlement in Iquitos, Peru. With technical support from the Centers for Disease Control and Prevention (CDC), CARE Peru's Urban Environmental Health Models (Modelos Urbanos de Salud Ambiental [MUSA]) project built on previous work from implementing the Protocol for Assessing Community Excellence in Environmental Health in this same community. The project led to the municipal water supply distribution system being extended 1.3 kilometers into the Southern zone of Iquitos, where it connected to the condominial water system. Altogether, 1030 households were connected to the water supply system after the installation of a condominial water and sewerage system in Cardozo. Diarrheal disease decreased by 37% for children less than 5 years of age from 2003 to 2004. This paper illustrates the strategy used by CARE Peru in conjunction with the Cardozo community to assure that the local demand for improved water and sanitation was met.

Health impact of water and sanitation infrastructure reconstruction programmes in eight Central American communities affected by Hurricane Mitch.

In response to Hurricane Mitch, which struck Central America in October-November 1998, the American Red Cross (ARC) and the Centers for Disease Control and Prevention (CDC) collaborated on a 3-year evaluation of the public health impact of ARC's water, sanitation and hygiene education activities in eight study areas in Honduras, Nicaragua, El Salvador and Guatemala. The evaluation compared: 1) access to and use of water and sanitation facilities, 2) the use of hygienic behaviours, and 3) diarrhoeal prevalence in children younger than 3 years of age before (February 2000) and after (February 2002) the interventions had been implemented. The evaluation included household and key informant interviews designed to measure these three components. Water quality of community water sources and household water was evaluated by measuring levels of indicator bacteria. During the final survey, an infrastructure evaluation provided a review of the design, construction, and current operation and maintenance of the water systems and latrines. The integrated water and sanitation infrastructure interventions and hygiene education programmes implemented following Hurricane Mitch effectively decreased diarrhoea prevalence in the target communities.

Community environmental health assessment strengthens environmental public health services in the Peruvian Amazon.

In December 1999, the Centers for Disease Control and Prevention (CDC) and the Cooperative for Assistance and Relief Everywhere, Peru Country Office (CARE Peru), initiated the Urban Environmental Health Project (SAU, in Spanish) to strengthen environmental public health services in urban and periurban settlements in Peru. The project received funding from the Woodruff Foundation as part of the CARE-CDC Health Initiative (CCHI). The "Protocol for Assessing Community Excellence in Environmental Health" (PACE EH) guided the development of a community environmental public health assessment (CEHA) process in Cardozo, a settlement in Iquitos, Peru. The project developed a three-phase process that merged scientific understanding and community perception about local environmental health problems. In phase 1, local environmental health technicians assisted the community in understanding environmental health conditions in Cardozo and selecting priorities. During phase 2, local technicians assessed the community-selected priorities: water and sanitation. Results from recent water quality assessments revealed that 82% (9 of 11) of samples from shallow dug wells, 18% (2 of 11) from deeper drilled wells, and 61% (11/18) from household drinking containers were positive for thermotolerant coliforms. Phase 3 activities produced an action plan and an intervention to mitigate health problems associated with inadequate water and sanitation services in the Cardozo community. As a result of the CEHA process, CARE Peru obtained funding from the United States Agency for International Development (USAID) to develop and implement an environmental health risk monitoring system and the proposed water and sewage intervention in the settlement. CDC continues to provide technical assistance to the local environmental health services groups in Iquitos through an agreement with CARE Peru as part of the USAID-funded Urban Environmental Health Models Project (MUSA). Technical assistance activities and the development of the environmental health risk monitoring system have helped to strengthen the local environmental public health services delivery system.
