Fig. 1From: Metagenomic analysis reveals differences in the co-occurrence and abundance of viral species in SARS-CoV-2 patients with different severity of diseaseAbundance of human viral species in SARS-CoV-2 positive samples. Sequence reads were normalized according to the total number of reads after quality filtering. The abundance is shown in logarithmic scale (log10). Samples from ambulatory, severe and deceased patients are separated verticallyBack to article page
