“Reworking Wikipedia health entries is not a trivial task. A 2014 study found about 25,000 pages of English-language health-related articles. That number is now up to 32,000, Heilman says. The health pages worldwide attracted almost 4.9 billion pageviews in 2013. A 2012 survey of several hundred medical students found 94 percent use the site for health information.
But despite its popularity, the reliability of Wikipedia’s medical content has often been questioned.”
