Comment: in Italian languageWith the appearance of SARS-CoV-2, two epidemics have spread: one for health and one for information. The virus has generated an unprecedented infodemic, contributing to the establishment of a climate of great uncertainty. Massive and redundant information has also been an effective vector of propaganda, on a global scale, by state and non-state actors. A real hostile act in which physical violence is not foreseen, but systematic management of information through the manipulation of the cognitive sphere. For this reason, the adoption of an attitude of active critical analysis by citizens and institutions and also the implementation of common policies at an international level could undoubtedly facilitate the fight against cognitive warfare (so-called cognitive warfare) and therefore limit its disastrous effects.
