CD14 and hemorrhagic fever with renal syndrome: CD163 expression on the CD14++CD16+ monocyte was more remarkable during the acute phase (median = 64.2%, IQR = 38.8%–88.5%, P<0.0001) than during the convalescent phase (median = 17.3%, IQR = 11.3%–24.5%) in the HFRS patients and healthy controls (median = 16.3%, IQR = 9.4%–21.3%); however no significant (P>0.05) differences were observed during the convalescent phase and in the healthy controls.
