Barriers and Facilitators to Chlorine Tablet Distribution and Use in Emergencies: A Qualitative Assessment

Publication year
2019
Emergency type
Country

Chlorine tablets are commonly distributed for household water treatment in emergencies. However, confirmed use after distribution ranges widely (from 7–87%), which raises concerns about chlorine tablet effectiveness, as measured by acceptance and appropriate use. To investigate chlorine tablet effectiveness, we conducted nine key informant interviews (KIIs) on tablet distribution in emergencies in general, five KIIs on chlorine taste and odor acceptance and rejection specifically, and a literature review on chlorine taste and odor concerns.

Water, sanitation, and hygiene access in southern Syria: analysis of survey data and recommendations for response

Publication year

Country

Background. Water, sanitation, and hygiene (WASH) are immediate priorities for human survival and dignity in emergencies. In 2010, > 90% of Syrians had access to improved drinking water. In 2011, armed conflict began and currently 12 million people need WASH services. We analyzed data collected in southern Syria to identify effective WASH response activities for this context.

Effectiveness of Multilevel Risk Management Emergency Response Activities To Ensure Free Chlorine Residual in Household Drinking Water in Southern Syria

Publication year

Country

To provide safe drinking water and reduce the risk of disease, emergency responders in southern Syria are implementing a multilevel risk reduction strategy with the aim of ensuring free chlorine residual (FCR) in household drinking water. Responders implemented activities across the water chain (from chlorination station and well operators to water vendors to household members), including distribution of supplies for chlorination and training on chlorine use; activities varied by responder.

Water, sanitation, and hygiene interventions in outbreak response: a synthesis of evidence

Publication year

Country

Water, sanitation, and hygiene (WASH) interventions are key to reducing the burden of disease associated with outbreaks, and are commonly implemented in emergency response. However, there is a lack of summarized evidence on the efficacy and effectiveness of these interventions. We conducted a systematic review of published and grey literature by developing theory of change models, developing inclusion criteria, conducting the search, selecting evaluations for inclusion, assessing the quality of the evidence, and analysing the included evaluations.

Chlorination of drinking water in emergencies: a review of knowledge to develop recommendations for implementation and research needed

Clean water provision is a critical component of emergency response, and chlorination is widely used in emergencies to treat water. To provide responders with practical, evidencebased recommendations for implementing chlorination programmes and recommend areas for future research, we conducted a literature review of chlorination in emergencies, supplemented with a literature review on chlorination in general.

WASH Interventions in Disease Outbreak Response: Evidence Synthesis.

Publication year
2017
Country

This evidence synthesis identifies, synthesizes and evaluates existing evidence of the impacts of water, sanitation, and hygiene (WASH) interventions in disease outbreaks in 51 humanitarian contexts in 19 low and middle-income countries. The research team developed theories of change for the WASH interventions under consideration, documenting the theoretical route from intervention activities to outputs, outcomes, and impacts. WASH interventions consistently reduce both the risk of disease and the risk of transmission in outbreak contexts.

There are increasing numbers of people affected by natural disasters, disease outbreaks, and conflict. Water, sanitation, and hygiene (WASH) interventions are used in nearly all emergency responses to help reduce disease risk. However, there is a lack of summarized evidence on the efficacy and effectiveness of these interventions.

Household Water Treatment and Cholera Control

Water,  sanitation,  and  hygiene  are  one  part  of  a  cholera  control  strategy.  Household  water  treatment  (HWT)  in  particular  has  been  shown  to  improve  the  microbiological  quality  of  stored  water  and  reduce  the  disease  burden.  We  conducted  a  systematic  review  of  published  and  gray  literature  to  determine  the  outcomes  and  impacts  of  HWT  in  preventing  cholera  specifically.  Fourteen  manuscripts  with  18  evaluations  of  HWT  interventions  in  cholera  were  identified.  Overall,  a  moderate  quality  of  evidence  suggests  that  HWT  int
