Type and distribution of the lesions according to positivity or negativity to SARS-CoV-2 infection. The interstitial pattern is the more frequent imaging finding in SARS-CoV-2 patients. The distribution is typically bilateral, subpleural, and diffuse. No statistically significant difference was found between SARS-CoV-2 positive and negative patients.
