The Alliance for International Medical Action (ALIMA) is an international medical organization, founded in 2009. ALIMA’s aim is to provide a high standard of healthcare in situations of emergency or medical disaster and to improve the practice of humanitarian medicine by developing innovative projects associated with medical research. The specific feature of the association is to base its operating methods mainly on partnership with national medical players. By pooling and capitalizing on their skills, ALIMA and its partners give as many people as possible access to a high standard of treatment. Since its creation, the association and its partners have successfully developed in line with the increase in humanitarian medical needs, especially in Western and Central Africa: 580,000 patients treated in 2014 including over 25,000 hospitalizations, new governance between the partners of the medical NGO platform in the Sahel, new innovative approaches and operational research projects. ALIMA also responded to the Ebola emergency by opening a 40-bed Ebola treatment centre in Guinea. With operations in eight countries, 15 projects, over 1,200 employees and a budget of €19.5 million, ALIMA is a dynamic NGO, effectively deploying medical aid for the most vulnerable.
