Covid-19 is an infectious severe acute respiratory syndrome, caused by Coronavirus, which quickly reached pandemic levels. In July/2020, Brazil was the second country most affected by the disease, exceeding two million cases. Despite the increasing scientific literature on Covid-19, its containment is still compromised by the lack of understanding about its determinants and complications. This article presents a discussion on aspects related to Covid-19 complications and its effects on Unified Health System (SUS), aiming at planning new coping strategies. Additionally, it is pointed out that the overload of the health system does not result only from aspects associated with the assistance to Covid-19, but adds to the pre-existing health needs, whose care strategies were postponed and/or changed due to the actions transmission control. It is evident, then, the need to reinforce the action of Primary Health Care as the ordering of care in SUS, acting in the management of the reorganization of flows and in the improvement of the physical structures of the units. To this end, the end of measures to limit health resources is essential, since not only does the success of coping with Covid-19 depend on this, but also the future of SUS and Brazilian’s health.
