Fig. 1: SARS-CoV-2 viral loads across sampling sites and detection rates by disease severity.
From: SARS-CoV-2 viral load is associated with increased disease severity and mortality
a Levels of SARS-CoV-2 viral loads at the time of initial sampling and across specimen types. The percent of samples with detectable viral loads are shown at the bottom. b Percent of participants with detectable plasma SARS-CoV-2 viral load by hospitalization status and disease severity. Symptomatic nasopharyngeal swab positive (NP+) and negative (NP−) individuals were evaluated at an outpatient respiratory infection clinic. Recovered individuals included participants who had previously been diagnosed with COVID-19, but whose symptoms have since resolved. P values are from a Χ2 analysis.
