Fig. 2From: An in vitro model for assessment of SARS-CoV-2 infectivity by defining the correlation between virus isolation and quantitative PCR value: isolation success of SARS-CoV-2 from oropharyngeal swabs correlates negatively with Cq valueThe distribution of Cq values during the outbreak in a total data set of 371 samples (dark grey). The light grey bars show the comparable distribution of Cq values in our experimental sample collection and demonstrate that our sample set is representative for the distribution of initial viral loads during an outbreak of SARS-CoV-2Back to article page
