Since July 2006, the Global Early Warning and Response System for Major Animal Diseases, including Zoonoses (GLEWS) monitors outbreaks of major animal diseases, including zoonoses, worldwide. GLEWS is the result of the cooperation between the UN Food and Agriculture Organization (FAO), the World Organization for Animal Health (OIE) and the World Health Organization (WHO). It was created to improve the early warning capacity for animal disease threats of the three sister organizations for the benefit of the international community. Publicly available products are maps and short outbreak reports online. They include information like the dates of event, report, confirmation, submission and resolution (if not ongoing), reasons for submission, location and scope of the outbreak, number of outbreaks, other epidemiological comments and links to reports by member countries with additional information. The system helps for disease tracking, sharing information and aid operations. By sharing information through GLEWS, the three partner organizations prevent the duplication of efforts. Main users are thus FAO, OIE and WHO themselves and the general public.
