Covid-19 pandemic: from carnival masks to surgical masks

Given the high transmissibility of SARS-CoV-2, COVID-19 pandemic has a huge impact on our health system. Even in developed countries, strategic resources soon become insufficient. Although people over 60 and with comorbidities are at greater risk of developing severe forms, younger people may also require precious and scarce care. Hence, the World Health Organization recommend tests - PCR and serological tests - for detecting infected people on a large scale. The most common symptoms are fever, fatigue, dry cough, anorexia, myalgia, and dyspnea, with tomographic pulmonary findings being frequent even in asymptomatic cases. The Brazilian Society of Nephrology has published guidelines for the management of hypertensive, diabetic, dialysis, and transplant patients. In its alerts, care and precautions in dialysis units are also being detailed, both for the health team and for the patients. Although important renal manifestations are not yet evident in the admission of positive cases, recent studies with renal patients and performed in nephrology services are listed here. This pandemic lead us to learn from its progress in order to face new challenges in dialysis clinics, transplant services, and intensive care services.
