With the increase in frequency of disasters, there is a need to improve early warning systems (EWS) for EA to reduce the risks faced by children and their families. As a consequence, the term early warning, early action (EWEA) has become increasingly common among those responding to slow-onset disas...ters.

Early warning systems for disease outbreaks are surveillance systems that collect information on a selected list of epidemic-prone diseases in order to trigger prompt public health interventions. They function in humanitarian emergency situations when the routine public health surveillance systems o...f a country are underperforming, disrupted or non-existent. Early warning systems are often set up to fill such temporary gaps, while the routine systems recover from the effects of the disaster or a crisis. During humanitarian emergencies, detecting and responding swiftly to epidemics is key in order to reduce unecessary illness and death, especially among refugees and displaced people.

Climate information is critical towards strengthening the decision making among different users interested in mitigating impacts of climate related disasters. However, there is need for the climate users to have basic knowledge on weather and climate concepts and to a larger extend, early warning ea...rly action (EWEA) system and approach. This manual presents an opportunity for the climate users including communities to acquire basic knowledge on Early Warning Early Action and this entails; understanding risk areas, existing early warning systems, communication of early warning information and enhancing disaster preparedness through translating early warning into early actions. The EWEA manual largely target the users in different sectors and communities. The execution of the EWEA manual is planned for 3 days and this does incorporate different methods such as; PowerPoint presentation, group work discussions as well as practical exercises.

The Global Early Warning – Early Action (EWEA) report on food security and agriculture is developed by the Food and Agriculture Organization of the United Nations (FAO). The report is part of FAO’s EWEA system, which aims to translate forecasts and early warnings into anticipatory action.
The document titled "Early Warning Signs of COPD" from the American Lung Association outlines what COPD is, its risk factors, and the importance of recognizing early symptoms such as persistent cough, breathlessness, and frequent chest infections. It emphasizes the need for early consultation with a... healthcare provider and diagnostic testing like spirometry to confirm COPD. Early diagnosis and treatment can help slow disease progression and improve quality of life.

Early warning systems are an essential tool for risk management and disaster preparedness that help save lives and minimize the potential impact of disasters. To be effective, early warning systems need to rely on the direct participation of at-risk communities, facilitate public education and aware...ness of risks, disseminate messages and warnings efficiently, and help maintain a constant state of preparedness to enable early action.

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.

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.

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.
