Abstract

Image in medicine SARS-CoV-2 is the coronavirus responsible for the COVID-19 pandemic of 2020. The mean incubation time is 5.1 days (95% CI: 4.5-5.8 days), with 97.5% of those who develop symptoms within 11.5 days (95% CI: 8.2-15.6 days).

He had had no recent travel outside of the state or internationally. Admission vital signs were normal. The results of routine laboratory parameters are shown: leucocytes 10,78x103/mmc, lymphocytes 40%, D-DIMERO 1.739ng/mlFEU,PCR 20,54mg/dl, Pro-CALCITONIN 0,20ng/ml, ferritin 2.925,0ng/ml. Arterial Blood Gases pH 7,50,PCO2 27,0 mmHg, PO2 46,0 mmHg, PO2/FiO2 (P/F ratio) 219,0 mmHg. Nose and throat samples for SARS-CoV-2 PCR were positive. Examination of the lungs reveals murmure reduced. The test result returned positive. A CT chest showed bilateral peripheral ground-glass opacities (figure 1). He was treated with oxygen therapy, azithromicin 500mg/day, hydrossicloroquine 400mg/day and enoxaparin. Tocilizumab was not necessary. The patient improved and was discharged 15 day after.
