[The parallel epidemic.]

The paper is a reflection on the psychic phenomenon involving the denial of reality of covid-19 pandemic, the denial of data from scientific research about it and the denial of therapeutic purposes of vaccine and national and international health policies, as it emerges in the frame of the so-called no-vax movements. The possible basic or associated psychopathological pictures are described, analogies and differences respect to classic psychiatric nosology are evaluated, psychological and psychiatric interpretative hypotheses are considered, in what they can to some extent characterize a wide and complex reality, in whose knowledge and management psychiatrists could play a much more relevant role than they actually do.
