Discourse analysis of physicians on Twitter about the validity of possible treatments for COVID-19
Introduction: Twitter is a platform that prioritizes the immediacy of communication; nevertheless, tweets in scientific areas rarely reach a wide audience. Objective: To examine discursive strategies used by Peruvian doctors with an active Twitter account on the validity of possible treatments for COVID19. Methodology: Critical discourse analysis - using Fairclough's three-dimensional model - with the help of notions of ethos. Results: Two areas were found where the medical-scientific discursive ethos is expressed: the construction as individual specialists in health and the approach given to the aspects of the medical-scientific ethos: the method, the evidence and the pseudo-scientific. Conclusions: The language used in the tweets is impersonal and neutral. The positioning of individuals as health specialists is through a thematic opinion. A discursive ethos that reinforces the existing pre-discursive ethos through discursive strategies such as denomination and intertextuality develops this positioning.
