Using two auxiliary hypotheses, the initial hypothesis The media do not provide credible information in their publications on topics on which citizens would develop a clear and unambiguous attitude towards the current situation and the whole against COVID-19 was rejected. The results of the content analysis could be seen as most of the articles contain appropriate scientific sources with the aim of educating citizens about the pandemic and the whole against COVID-19.
