Neste contexto, o artigo tem como objetivo realizar um estudo da comunicação no Twitter de Jair Bolsonaro, Presidente do Brasil, durante a pandemia da Covid-19. Nesse período, o presidente brasileiro se posicionou contra as medidas de isolamento social e fez a defesa de medicamentos sem eficácia para o tratamento da Covid-19, o que gerou dificuldades para o combate da epidemia no país. Visando estudar as estratégias de comunicação adotadas por Bolsonaro durante o período inicial da pandemia, o estudo realizou uma análise em dois níveis: (i) análise de tópicos de todas as publicações no período; e (ii) análise de conteúdo das 100 mensagens mais retuitadas. Os resultados indicam que a estratégia de comunicação populista, evocando emoções de raiva e com porcentagem relevante de desinformação, produz os conteúdos que são mais compartilhados por seus seguidores.]]></p></abstract>

This article studies the Brazilian president Jair Bolsonaro&#8217;s Twitter communication during the pandemic of Covid-19. During this period, the Brazilian president took a stand against the measures of social isolation and defended medicines that were not effective for the treatment of Covid-19, which created difficulties for the fight against the epidemic in the country. Aiming to study the communication strategies adopted by Bolsonaro during the first months of the pandemic, the study realized a two level analysis of his Twitter publications: (i) a topic analysis of all publications within the period; and (ii) a content analysis of the 100 most retweeted messages. The results indicate that the populist communication strategy, evoking angry emotions and with a relevant percentage of disinformation, produces the contents that are most shared by its followers.]]></p></abstract>
