The article reveals the content of the philosophical and communicative phenomenon of post-truth, which describes the current state of public discourse, where the boundaries between objective reality and the virtual environment are blurred. It is shown that the main issue in the study of the information foundations of post-truth is the interaction of the media narrative with the mass audience’s subjective beliefs. The classification of post-truth markers in the digital media space is given. The relationship between the concepts of «post-truth», «infodemic» and «simulacrum», due to the communicative specifics of the pandemic era, has been established.
