In the context of globalization, public health requires continuous cooperation among all actors and a flow of data and information that facilitates and leverages that cooperation. However, there are still barriers that limit or prevent access to and use of public health for the benefit of societies. In this context, the adoption of open public health is proposed and its implications and scope are explored. Open public health is understood as data, information and knowledge aimed at improving public health, which are shared and developed through collaborative networks without restrictions on access and use and with continuous protection of privacy, security and confidentiality of sensitive data or data requiring special protection.
