This issue highlights recent alerts, news and publications on cholera and Ebola outbreaks. On August 1, 2014, WHO published its latest statistics on the number of cholera cases and cholera-related deaths in 2013. In 2013, there was a 47% decrease in the number of cases reported compared to 2012 and this is the second consecutive year in which reported cholera era cases declined. Resources on the Ebola outbreaks include WHO alerts, a WHO fact sheet, recent newspaper articles and reports on the One Health approach, which investigates human, animal, and environmental interconnectedness and its impact on health.

CHOLERA STATISTICS/FACT SHEETS

Cholera Fact Sheet, 2014. World Health Organization. (Link)
Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. Every year, there are an estimated 3–5 million cholera cases and 100,000–120,000 deaths due to cholera. The short incubation period of two hours to five days enhances the potentially explosive pattern of outbreaks.

GENERAL/OVERVIEW

Human Health and the Water Environment: Using the DPSEEA Framework to Identify the Driving Forces of DiseaseScience of the Total Environment, 2014. J Gentry-Shields.(Link)

There is a growing awareness of global forces that threaten human health via the water environment. A better understanding of the dynamic between human health and the water environment would enable prediction of the significant driving forces and effective strategies for coping with or preventing them. This report details the use of the Driving Force–Pressure–State–Exposure–Effect–Action (DPSEEA) framework to explore the linkage between water-related diseases and their significant driving forces.

Seasonal Effects of Water Quality: The Hidden Costs of the Green Revolution to Infant and Child Health in India, 2013. E Brainerd. (Link)
This paper examines the impact of fertilizer agrichemicals in water on infant and child health using water quality data combined with data on child health outcomes from the Demographic and Health Surveys of India. The results indicate that children exposed to higher concentrations of agrichemicals during their first month experience worse health outcomes on a variety of measures; these effects are largest among the most vulnerable groups, particularly the children of uneducated poor women living in rural India.

Water, Sanitation and Hygiene: Evidence Paper, 2013. Department for International Development. (Link)
This paper aims to provide an accessible guide to existing evidence, including a conceptual framework for understanding how WASH impacts health and well-being and a description of methods used for ascertaining the health, economic, and social impacts of WASH. It also presents the available evidence on the benefits and cost-effectiveness of WASH interventions.

These manuals are free to download and distribute. New users must create an account to download the manuals, which are divided into disease-specific chapters that describe the transmission cycle, symptoms, and disease burden of the WASH-related NTDs. Each chapter includes information about WASH activities that are most essential to the control of each disease. Maps of disease prevalence are provided to enable identification of disease-endemic communities most in need of sustainable WASH services. Country-specific versions of the manual are available so far for Brazil, Burkina Faso, Cameroon, Chad, Ethiopia, Indonesia, Kenya, Malawi, Mali, Mozambique, Nigeria, Sudan, Tanzania, and Uganda.

WASHplus Weekly: Cholera Prevention and Control

This issue updates the August 2012 Weekly with studies and resources published in 2013 on cholera prevention and control. Included are the latest statistics from WHO on the number of cholera cases and deaths. WHO states that annual figures in this report exclude the estimated 500,000–700,000 annual cases labeled “acute watery diarrhea” occurring in southeastern and central Asia. The actual numbers of cholera cases are known to be much higher than those reported. Other resources in this issue are the 2013 Cholera Toolkit by UNICEF, studies on socioeconomic and environmental factors that affect cholera outbreaks, country studies from Bangladesh, Cameroon, Haiti, and other studies.

UNICEF launches groundbreaking cholera toolkit

To tackle the alarming resurgence of cholera, UNICEF has launched a new comprehensive Cholera Toolkit on 15 May 2013.

The toolkit launch [...] will be the culmination of a thorough review of existing guidance and global consultation with UNICEF at all levels and from all divisions in Africa, along with main partners in the fight against cholera, such as the World Health Organization as the lead agency.

There are 3-5 million cholera cases each year, killing 100,000 to 120,000 people, half of whom are children under 5 years old. Only 5-10% of cases are reported. In Western and Central Africa, there were more than 80,000 cases of cholera in 2012 resulting in nearly 1,500 deaths.

The Toolkit provides the health and WASH sectors an integrated approach to cholera prevention, preparedness and response. In addition it includes specific content linked to education, nutrition, communication for development (C4D), child protection and other relevant sectors.

“What the toolkit does is harvest the best and most up-to-date knowledge in the field and brings it together in one location,” said UNICEF Chief of Water, Sanitation and Hygiene Sanjay Wijesekera. “It looks at the evidence. It looks at practices that have produced results.”

Oxfam publishes advice on handling a cholera outbreak – but are we right?

Source: Oxfam Policy and Practice Blog, Aug 13, 2012, by Elizabeth Lamond, HSP Public Health Engineer Coordinator

Oxfam’s Cholera Outbreak Guidelines were developed as an internal resource, but today we are sharing them externally in order to seek input from the international humanitarian community. We hope that this feedback will inform later editions in order to develop a powerful resource for anyone looking to prepare for, prevent and control a cholera outbreak. Here, one of the authors of the Guideline, Bibi Lamond, explains more. 

I have been responsible for implementing and coordinating cholera outbreak programmes since 2006. In my work I have found that, although there are numerous documents and books on medical intervention for cholera control, there are no comprehensive water, sanitation and hygiene promotion (WASH) guidelines.

Oxfam’s new publication, the Cholera Outbreak Guidelines aims to meet this need and could set standards for other emergency WASH actors.

The content of the Guidelines has evolved from firsthand field experience in Oxfam’s emergency cholera programmes in Haiti, Democratic Republic of Congo, Ethiopia and Zimbabwe. It has also drawn on information from other NGOs, such as Médecins Sans Frontières, renowned for their cholera work in the field.
