Abstract
Thousands of articles have been published regarding the coronavirus disease of 2019 (COVID-19). Most of them are not original research articles but reviews and editorials, and therefore, the absence of evidence-based guidelines has been evident. In parallel, the quality of manuscripts is questionable since the number of preprints has increased due to the need of fast publication of COVID-19-related articles. Furthermore, the number of retracted articles during the pandemic is exceptionally high. Media have an important role in the distribution of incorrect information, nevertheless individual people and policy makers are also responsible. As misinformation thrives in crisis periods, well-designed studies are needed to flatten the infodemic curve regarding prevention, diagnosis, and long-term complications of COVID-19.
