Cholera is an acute diarrhoeal infection caused by ingestion of contaminated water or food. It can lead to dehydration, and death in patients with severe forms of the disease.
The WHO’s Early Warning, Alert and Response System (EWARS) is a tool used in emergencies such as conflicts or natural disasters to quickly detect and respond to disease outbreaks. It helps set up simple and reliable surveillance systems even in places without stable electricity or internet, using ...kits that include phones, laptops, and solar chargers. EWARS supports national health authorities during crises and can later be integrated into the regular health surveillance system.

Educational materials include resources for children and adolescents, such as children's books, textbooks, lesson plans, activities, games, and online resources on disaster prevention and school safety.
Go.Data is a software for contact tracing and data collection in outbreak response developed by WHO in collaboration with partners in the Global Outbreak Alert and Response Network (GOARN). Go.Data focuses on case and contact data, including laboratory data, and on contact follow-up and visualizatio...n of chains of transmission.

EWARS is a surveillance system developed by the World Health Organization to detect and respond quickly to disease outbreaks in emergency settings where normal health systems are disrupted. It allows health facilities to report priority diseases on a regular basis and generates alerts when unusual p...atterns or suspected outbreaks occur. The system is designed to be simple and fast to set up, even in remote areas, and supports rapid public health action to prevent the spread of disease during crises.

The webpage introduces the “Health Cluster Coordination” channel on World Health Organization’s OpenWHO platform, focusing on training and resources for coordinating health-cluster operations in humanitarian emergencies. It outlines how participants can learn about setting up and managing heal...th clusters, establishing collaboration among partners, and ensuring effective service delivery in crisis settings.

Strengthening global health security to protect the world against future epidemics and pandemics requires well-tested and decentralized capacities for the local detection and rapid containment of outbreaks of infectious disease. For such capacities to translate into effective response actions, ind...ividuals and teams must be well connected and coordinated, despite differences in the size, geography, technical focus or constituency of their parent institution.

The document provides a standardized protocol for evaluating the Early Warning Alert and Response Network (EWARN), a surveillance system used during humanitarian emergencies when regular national health surveillance may be disrupted. The purpose of EWARN is to detect outbreaks of communicable diseas...es early and enable rapid public health response. The guidance explains how the system should be assessed in terms of its structure, implementation, effectiveness, and usefulness. It outlines the key steps of evaluation: preparation, system description, data collection, and post-evaluation reporting. The protocol highlights common challenges observed in previous EWARN implementations, such as delays in establishing the system, limited data quality, weak outbreak response, and lack of clear transition plans back to routine surveillance systems. It emphasizes the need to evaluate both weekly disease reporting and alert verification processes, and to review attributes such as simplicity, data quality, timeliness, sensitivity, and stability. The document also provides templates for interviews, data review forms, and laboratory assessment, as well as guidance on conducting remote evaluations when access is limited. The overall goal of the protocol is to ensure that EWARN functions effectively to detect and respond to outbreaks and that practical recommendations are developed to improve the system’s performance and sustainability in emergency settings.

Cholera epidemics continue to be a major public health problem in many countries around the
world. When epidemics strike, they can spread rapidly. The disease can also evolve quickly;
patients with severe disease can die of dehydration hours after showing the first symptoms of
cholera.
