[How to fight infodemic and health obscurantism]

Physicians, pharmacists and caregivers, as well as public health officials and citizens, must sort through the enormous amount of information circulating about the pandemic. This crisis is accompanied by a real « infodemic » via multiple media, digital and otherwise. Is circulating a mixture of reliable information but also of misinformation, fed by the obscurantism jeopardizing the implementation of interventions such as vaccination or mask-wearing.

Debuting rumors - « see something, say something » - and promoting credible information limit misinformation. Strengthening people's knowledge in population health science would also help.
