Introduction A cholera epidemic began in Haiti over 8 years ago, prompting numerous, largely quantitative research studies. Assessments of local ‘knowledge, attitudes and practices’ relevant for cholera control have relied primarily on cross-sectional surveys. The voices of affected Haitians have rarely been elevated in the scientific literature on the topic.
Description of the targeted WASH response strategy implemented during the cholera outbreak of 2017-2018 in Kinshasa, DRC
Background. Rapid control of cholera outbreaks is a significant challenge in overpopulated urban settings, and documented results on field interventions are scarce. During the 2017-2018 period, Kinshasa, the capital of Democratic Republic of the Congo, experienced a sharp increase in cholera cases that showed potential to quickly spread throughout the city. A novel targeted WASH (Water, Sanitation and Hygiene) strategy was implemented to quickly stem the cholera outbreak.
For people affected by disaster, whether wars, earthquakes, or disease epidemics, conditions of life can change suddenly and in ways that require rapid adjustments. Often, adaptation includes taking greater care to prevent transmission of disease, in order to minimize the new threats to public health.
This report is the first installment of the ‘Social Science in Epidemics’ series, commissioned by the USAID Office of U.S. Foreign Direct Assistance (OFDA). In this series, past outbreaks are reviewed in order to identify social science ‘entry points’ for emergency interventions and preparedness activities.
Cholera has been eliminated as a public health problem in high-income countries that have implemented sanitation system separating the community’s fecal waste from their drinking water and food supply. These expensive, highly-engineered systems, first developed in London over 150 years ago, have not reached low-income high-risk communities across Asia.
Formative research for the design of a scalable water, sanitation, and hygiene mobile health program: CHoBI7 mobile health program
Background. The Cholera-Hospital-Based-Intervention-for-7-Days (CHoBI7) is a handwashing with soap and water treatment intervention program delivered by a health promoter bedside in a health facility and through home visits to diarrhea patients and their household members during the 7 days after admission to a health facility.
Cholera continues to be a significant problem in humanitarian settings, with recent outbreaks in displaced populations in South Sudan, Yemen, Cameroon, Nigeria, Tanzania, Uganda, Haiti, and Iraq. The success of cholera prevention and control in refugee camps over the past 2 decades highlights the possibility of managing this deadly disease, even in complicated humanitarian crises.
Water, sanitation and hygiene partners collaborating to combat severe cholera outbreaks during the State of Emergency in Zimbabwe
This paper aims to understand the value of collaboration in a ‘state of emergency’ situation, featuring the case of the water, sanitation and hygiene (WASH) sector in Zimbabwe over the period 2008–2012. During this period, a group of stakeholders engaged in a structured collaboration, called the WASH cluster. This initiative was taken to respond to severe and frequent cholera outbreaks.
Bucket chlorination (where workers stationed at water sources manually add chlorine solution to recipients’ water containers during collection) is a common emergency response intervention with little evidence to support its effectiveness in preventing waterborne disease. We evaluated a bucket chlorination intervention implemented during a cholera outbreak by visiting 234 recipients’ homes across five intervention villages to conduct an unannounced survey and test stored household drinking water for free chlorine residual (FCR).
Evaluation of an Emergency Bulk Chlorination Project Targeting Drinking Water Vendors in Cholera-Affected Wards of Dar es Salaam and Morogoro, Tanzania
In August 2015, an outbreak of cholera was reported in Tanzania. In cholera-affected areas of urban Dar es Salaam and Morogoro, many households obtained drinking water from vendors, who sold water from tanks ranging in volume from 1,000 to 20,000 L. Water supplied by vendors was not adequately chlorinated. The Tanzanian Ministry of Health, Community Development, Gender, Elderly and Children and the U.N.
