Online Credibility of National Health Institutions: Infodemiological Analysis of Facebook Users' Reactions in Eight Countries Worldwide

Résumé

Public trust in physicians, health-related websites, and medical institutions is one of the main determinants of health behaviour. This paper aims to examine the online credibility of the leading national health authorities in various countries worldwide in order to estimate the extent of the reputation damage during the COVID-19 crisis and evaluate the countermeasures to be undertaken. Specifically, users' reactions to Facebook posts related to vaccine development and administration were studied. From 2021 to 2022, a sharp deterioration in the online credibility of the leading national health institutions worldwide has been observed. Infodemic reactions such as derision and anger, which already represented a health issue in 2021, have reached alarming percentages (i.e., between 30 and 50%) in England, France, Italy, Spain, and the USA during 2022. Such reactions reached a disproportionate 90% in Germany, where the online infodemiological situation appears incredibly serious. Conversely, the situation seemed more moderate in Argentina and Brazil (below 20%). Regardless of the sample size and its suitability for representing the global situation, these findings reveal a rising global security threat. Future research should focus on verifying how much of this online infodemic directly translates into dangerous health behaviours (e.g., vaccine hesitancy) and what were the main causes for these communication crises.
