RESUMO
The COVID-19 pandemic brought about an urgent need for public health departments to clearly communicate their prevention, testing, and treatment recommendations. Previous research supports that Twitter is an important platform that public health departments use to communicate crisis information to stakeholders. This study aimed to shed light on how international health departments shared relevant information about COVID-19 on Twitter in 2020. We conducted a quantitative content analysis of N = 1,200 tweets from twelve countries, across six continents. COVID-19 prevention behaviors were consistently referenced far more than testing or treatment recommendations across countries. Disease severity and susceptibility were referenced more than recommendation benefits, barriers, and efficacy. Results provide support for how public health departments can better communicate recommendations related to COVID-19 behaviors. Based on these results, implications for public health organizations and public relations practitioners worldwide are discussed, and hands-on action guidelines are provided.
