In addition, the data showed that hemoglobin, albumin and serum potassium were higher, and the erythrocyte sedimentation rate and C-reaction protein were lower for patients with EBV infection compared to the patients with EBV and CMV infection (Z = −4.367, p < 0.05; Z = −2.455, p < 0.05; Z = −4.207, p < 0.05; Z = −3.858, p < 0.05); while compared with those uninfected patients, albumin was lower and the erythrocyte sedimentation rate and C-reaction protein were higher in patients with EBV infection (Z = −2.357, p < 0.05; Z = −2.285, p < 0.05; Z = −2.935, p < 0.05; Table 2). The gene discussed is ALB; the disease is cytomegalovirus infection.
