∆Ct of SARS-CoV-2 positive patients with mild and severe symptoms of COVID-19. Patient RT-qPCR results were separated in four different groups based on days after the first symptoms and severity of the disease. Mild < 5 are ∆Ct values from 257 patients with mild COVID-19 symptoms tested until 5 days from the first symptoms (89% of them from the municipal Coronavirus Screening Center for COVID-19 patients-CTC), Severe < 5 are 20 patients hospitalized (80% of them) early after infection, or non-hospitalized patients with severity-related symptoms or still COVID-19 associated fatalities. The same classification was adopted for the patients with more than 5 days of symptoms:158 Mild > 5 (85% of them from the CTC) and 32 Severe > 5 (78% of them from hospitals). Significant differences among groups are represented by different letters above boxplots.
