Previously, it has been found that the serum levels of pro-inflammatory cytokines [IFN-γ, IL-1, IL-6, IL-12, and transforming growth factor-β (TGF-β)], and chemokines (CCL2, CXCL9, CXCL10, and IL-8) in SARS-CoV infected patients were higher than those in healthy individuals. Procalcitonin (PCT), released by bacterial infectious tissues under the irritation of pro-inflammatory cytokines, is a more specific marker of serious bacterial infection compared to C-reactive protein (CRP) and IL-6 [111] PCT-based strategy has been applied to guide antibiotic use in ICU or emergency wards, since the serum PCT levels in patients with severe bacterial infections are much higher than those with simple viral infections or non-specific inflammatory diseases [111] [112] [113] .
