In a recently published article, Reuters noted that Facebook Inc (FB.O) already knows who your friends are and the kind of things that grab your attention. The article reads that the social forum will soon be able to know the state of your health. On the heels of fellow Silicon Valley technology companies Apple Inc (AAPL.O) and Google Inc (GOOGL.O), Facebook is reportedly plotting its first steps into the fertile field of healthcare, three people familiar with the matter told the news agency. The people requested anonymity as the plans are still in development. According to Reuters, the company is exploring the possibility of creating online "support communities" that would connect Facebook users suffering from various ailments. A small team is also considering new "preventative care" applications that would help people improve their lifestyles. In recent months, the sources told Reuters, the social networking giant has been holding meetings with medical industry experts and entrepreneurs, and is setting up a research and development unit to test new health apps. Facebook is still in the idea-gathering stage, the people said. Healthcare has historically been an area of interest for Facebook, but it has taken a backseat to more pressing products. Recently, Facebook executives have come to realize that healthcare might work as a tool to increase engagement with the site. People would need anonymity and an assurance that their data and comments wouldn't be shared with their online contacts, advertisers, or pharmaceutical companies, Williams said. It remains unclear whether Facebook will moderate or curate the content shared in the support communities, or bring in outside medical experts to provide context. Facebook declined to comment on its health care plans.
