Abstract:

The uncertainties about COVID-19 require evaluation of national responses in order to identify successes and failures in its control. This article analyzes the Portuguese response, particularly the contribution of its health and surveillance systems in dealing with the pandemic. An integrative literature review was carried out, including consultations with observatories, documents, and institutional websites. The Portuguese response was agile and revealed unified technical and political coordination. It had a surveillance structure using telemedicine. The reopening was supported by high testing, low positivity, and strict rules. However, the measures relaxation as of November/2020 resulted in an increase in cases with collapse of the health system. The response to this situation involved a consistent surveillance strategy, with innovative monitoring instruments, which combined with the high adherence of the population to vaccination led to overcoming that moment and maintained low rates of hospitalizations and deaths in new waves. In this sense, the Portuguese case reveals the risks of a resurgence with flexibility, and the population´s exhaustion of restrictive measures and new variants, but also the importance of technical coordination, the political sphere, and the scientific committee articulation.
