This is pretty wild. They took scans of 104 patients from the cruise ship and of 104, 76 (73%) showed no symptoms including difficulty breathing yet ground-glass opacities were found in 54% of them.
That means that the disease was eating at their lungs even without any symptoms.
Remember that Harvard study which showed up to 80x the number of “asymptomatic” carriers could be out there…
From the paper:
Of 104 cases, 76 (73%) were asymptomatic, 41 (54%) of which had lung opacities on CT. Other 28 (27%) cases were symptomatic, 22 (79%) of which had abnormal CT findings. Symptomatic cases showed lung opacities and airway abnormalities on CT more frequently than asymptomatic cases [lung opacity; 22 (79%) vs 41 (54%), airway abnormalities; 14 (50%) vs 15 (20%)]. Asymptomatic cases showed more GGO over consolidation (83%), while symptomatic cases more frequently showed consolidation over GGO (41%). The CT severity score was higher in symptomatic cases than asymptomatic cases, particularly in the lower lobes [symptomatic vs asymptomatic cases; right lower lobe: 2 ± 1 (0-4) vs 1 ± 1 (0-4); left lower lobe: 2 ± 1 (0-4) vs 1 ± 1 (0-3); total score: 7 ± 5 (1-17) vs 4 ± 2 (1-11)].
