  COVID-19 first cases emerged in Wuhan, China, spreading across other countries, culminating in a global pandemic [1]. Regarding the analysis of the clinical characteristics of patients infected with the new coronavirus, although all ages are susceptible, the published studies showed an average age between 40 and 56 years and a higher incidence in men, but it is clear that more serious cases are related to older population and individuals with associated diseases (obesity, diabetes, heart disease) [2]. COVID-19 in some cases can progress to pneumonia, acute respiratory distress syndrome (ARDS) and multiple organ dysfunction [3].
