A new screening tool for SARS-CoV-2 infection based on self-reported patient clinical characteristics: the COV-ID score.

Background: While several studies aimed to identify risk factors for severe COVID-19 cases to better anticipate intensive care unit admissions, very few have been conducted on self-reported patient symptoms and characteristics, predictive of RT-PCR test positivity.
