Fig. 1 — Schematic diagram of radiographic scoring system. (a) Chest radiograph of a patient with MERS-CoV infection. (b) Schematic presentation of the extent of ground-glass opacity (GGO) and consolidation demonstrates a total score of 32, calculated as 2 (GGO) × 1 (≤25% distribution in middle zone of the right lung) + 3 (consolidation) × 2 (25%–50% distribution in lower zone of the right lung) + 2 (GGO) × 2 (25%–50% distribution in lower zone of the right lung) + 2 (GGO) × 3 (50%–75% distribution in middle zone of the left lung) + 3 (consolidation) × 1 (≤25% distribution in middle zone of the left lung) + 3 (consolidation) × 1 (≤25% distribution in lower zone of the left lung) + 2 (GGO) × 4 (over 75% distribution in lower zone of the left lung).
