COVID-19 3-month follow-up shows residual lung abnormalitiesA 3-month follow-up study of 142 COVID-19 survivors in China showed that 85.9% of patients had abnormalities on computed tomography (CT) chest scans and 52 (36.6%) had chronic and fibrotic changes.According to the study, published Nov 14 in Open Forum Infectious Diseases, higher CT scores (2.00 vs 0.00) and lower ground-glass opacity (GGO) absorption levels seemed to be associated with more severe COVID-19.
Among severe cases of COVID-19, 76.7% displayed higher CT abnormalities vs 37.5% of non-severe cases. GGOs in the lungs were completely absorbed in 77 patients (54.2%) and partially absorbed by 64 (45.1%) in the time from discharge to follow-up.
