Correlation between serum cytokines and chemokine concentration at the first week of illness and the peak MERS-CoV viral load in respiratory specimens. Hollow circles mean the values measured after the administration of pegylated IFN-α2a. Spearman’s rank correlation coefficient was used to assess correlations. (A) IFN-α, ρ = 0.938, P = 0.001; (B) IL-6, ρ = −0.320, P = 0.440; (C) CXCL-10, ρ = 0.419, P = 0.301.
