Public Health 2.0

Public Health 2.0 is the term given to a movement within public health that aims to make the field more accessible to the general public and more user-driven. There are three senses in which the term "Public Health 2.0" is used. In the first sense, "Public Health 2.0" is similar to the term "Health 2.0" and is used to describe the ways in which traditional public health practitioners and institutions are reaching out (or could reach out) to the public through social media and health blogs.^[28][29]

In the second sense, "Public Health 2.0" is used to describe public health research that uses data gathered from social networking sites, search engine queries, cell phones, or other technologies.^[30] In the third sense, "Public Health 2.0" is used to describe public health activities that are completely user-driven.^[31] An example this type of Public Health 2.0 is the collection and sharing of information about environmental radiation levels following the March 2011 tsunami in Japan.^[32] In all cases, Public Health 2.0 draws on ideas from Web 2.0, such as crowdsourcing, information sharing, and user-centred design.^[33]
