In contrast, viral protein expression was minimally detectable on blood vessels ( Figure 2 , B, dashed black line) or in the interstitial areas between alveoli (Figure 2, B, bottom panel, blue arrows) . Immu-nostaining of Huh7 cells infected with SARS-CoV and of lung sections from an HIV-positive patient who died of fungal infection served as positive and negative staining controls, respectively (Figure 2, C) . A. Histopathologic examination revealing diffuse alveolar damage, organizing phase (A-1); denudation of alveolar lining cells (arrow 1), with presence of reactive type II pneumocyte hyperplasia (arrow 2) (A-2); intra-alveolar fibrinous exudates (arrow 3) and interstitial loose fibrosis with chronic inflammatory infiltrates (arrow 4) (A-3); and intra-alveolar loose fibrous plugs (arrow 5) (A-4). B. Immunostaining of SARS-CoV-2 in lung sections.	./cache/cord-309513-dleo9rpl.txt	./txt/cord-309513-dleo9rpl.txt
