Wikipedia is a powerful public health knowledge-translation tool. Across all languages, medical-related Wikipedia articles receive over 10 million visits per day from around the world.[1] To improve the quality of health-related Wikipedia articles, the Cochrane-Wikipedia Initiative was developed in 2014. Presently, there are over 2000 uses of Cochrane Reviews in Wikipedia. Many Cochrane Groups are training Wikipedia editors and developing new ways to share high-quality evidence on Wikipedia. Wiley and the Cochrane Library have distributed over 85 free accounts to Wikipedians to support the sharing of Cochrane evidence on Wikipedia.
