Health surveillance in tackling COVID-19 in Brazil: a scope review.

The management of the COVID-19 pandemic in Brazil was marked by contradictory statements and controversial decisions by the head of the executive branch and the Ministry of Health, creating uncertainty about the effective implementation of federal actions to control the disease. This study aims to describe the main health surveillance strategies adopted by the federal government to combat COVID-19, with a focus on actions aimed at preventing SARS-CoV-2 infection. This is a scoping review conducted between November 2019 and January 2021, using DECS and MeSH descriptors in four databases, in addition to consulting 85 legislative documents available on the Brazilian government's legislation portal. The analysis included ten scientific articles and identified federal actions related to non-pharmacological and pharmacological measures, decisions on international borders, procurement of supplies, and essential services. The results point to the presence of sporadic strategies for pandemic containment but reveal insufficient surveillance in the face of the number of cases and deaths recorded. The study highlights the lack of robust federal support, which hindered the coordination and planning.
