This guidance document is based on research of social media activity related to antibiotic use at EU level, as well as on a survey of the social media activities of EAAD partner organisations, mostly EU umbrella organisations of patients and health professionals. The research showed that there is already some social media activity on prudent antibiotic use and that a few potential influencers are emerging. Similarly, the survey of the EU-wide partners of EAAD showed that respondents are becoming active on social media platforms.
