WHO has many successful partnerships, but one in particular stands out. Since its inception 20 years ago, the Global Outbreak Alert and Response Network (GOARN) has responded to crises in 85 different countries. It has deployed more than 2300 experts to help characterize and control disease outbreaks and to support countries to respond to natural disasters and humanitarian emergencies. Almost 900 deployments through GOARN mechanisms were from institutions based in the WHO European Region.
