Differential diagnosis of coronavirus disease 2019 from pneumonias caused by other etiologies in a fever clinic in Beijing

During this period, pneumonias caused by other etiologies such as influenza were also prevalent in Beijing, as in other regions of the country; it was a challenge for physicians to identify suspected COVID-19 from patients with fever, particularly from pneumonias of varied etiologies. [...]information was needed to help differentiate COVID-19 from pneumonias caused by other etiologies in this critical situation. For the remaining 91 cases with negative viral detection, 2 cases were not included in the final analysis because they had epidemiological evidence with interstitial pneumonia in CT findings and COVID-19 could not be completely excluded, 22 were excluded from the analysis because of lack of CT scan or no signs of pneumonia on CT scan, and finally 67 patients were included as the non-COVID-19 group [Supplementary Figure 1, http://links.lww.com/CM9/A337]. [3] A recent study demonstrated that serum albumin and C-reactive protein were also the risk factors for disease progression. [...]multi-lobe involvement was more common in COVID-19 as compared with non-COVID-19 pneumonia.
