This From a historical perspective, past and present catastrophic events like wars and epidemics teach us that huge psychological stressors have the potential to exert mental effects whose onset is often delayed by at least few months, if not more. In this scenario, a prompt detection of de novo psychotic experiences and relapses cannot disregard from priorities such as long-lasting sanitary surveillance and mass sensitization program, thus avoiding harmful underestimates of negative affective states (e.g. fear, anger, anxiety, depressed mood, etc.) and other putative factors involved in PSD pathogenesis.
