Sindemia, infodemia, pandemia de COVID-19: Hacia una pandemiología de enfermedades emergentes

As the basis for a theory of the co-occurrence of epidemic and pandemic processes, the article begins with a discussion of the concept of syndemic, created during the HIV/AIDS epidemic to understand the social, behavioral, and cultural components of emerging diseases, as is the case of the current COVID-19 pandemic. Secondly, the notion of infodemic is highlighted, which has great potential to better understand the impacts of the pandemic from approaches that are generally neglected in conventional epidemiological research. Third, in order to illustrate these points, a “micro-archaeological” case study of the infodemic resulting from the COVID-19 pandemic is presented, focusing on the specific situation in Brazil. Then, the correlations between scientific evidence, intervention models, and measures to control the pandemic are comparatively analyzed in different countries, as well as their adoption or rejection in the Brazilian context, which is structured by deep economic inequalities, social inequities, and health inequities.Como base para una teoría de la coocurrencia de procesos epidémicos y pandémicos, en primer lugar, se introduce el concepto de sindemia, creado en la epidemia de VIH/sida para comprender componentes sociales, conductuales y culturales de enfermedades emergentes, tal como la actual pandemia de COVID-19. En segundo lugar, se destaca la noción de infodemia, que tiene gran potencial para comprender los impactos de la pandemia desde planos que generalmente se descuidan en los enfoques epidemiológicos convencionales. En tercer lugar, como complemento e ilustración, se presenta un estudio de caso “microarqueológico” de la infodemia resultante de la pandemia de COVID-19, centrado en la situación concreta de Brasil. Luego, se analizan las correlaciones entre la evidencia científica, los modelos de intervención y las medidas para controlar la pandemia en varios países y su adopción o rechazo en la realidad brasileña, estructurada sobre profundas desigualdades económicas, inequidades sociales e inequidades en salud
