Objective Genotypes(G)1,3,and 5 of the Japanese encephalitis virus(JEV)have been isolated in China,but the dominant genotype circulating in Chinese coastal areas remains unknown.We searched for G5 JEV-infected cases and attempted to elucidate which JEV genotype was most closely related to human Japanese encephalitis(JE)in the coastal provinces of China. Methods In this study,we collected serum specimens from patients with JE in three coastal provinces of China(Guangdong,Zhejiang,and Shandong)from 2018 to 2020 and conducted JEV cross-neutralization tests against G1,G3,and G5. Results Acute serum specimens from clinically reported JE cases were obtained for laboratory confirmation from hospitals in Shandong(92 patients),Zhejiang(192 patients),and Guangdong(77 patients),China,from 2018 to 2020.Seventy of the 361 serum specimens were laboratory-confirmed to be infected with JEV.Two cases were confirmed to be infected with G1 JEV,32 with G3 JEV,and two with G5 JEV. Conclusion G3 was the primary infection genotype among JE cases with a definite infection genotype,and the infection caused by G5 JEV was confirmed serologically in China.

Objective:To investigate the incidence and risk factors of active human cytomegalovirus (HCMV) infection in patients with severe community-acquired pneumonia.Methods:Patients who required respiratory support and were diagnosed with severe community-acquired pneumonia in the respiratory intensive care unit (RICU) of the First Affiliated Hospital of Guangzhou Medical University from March 1, 2019 to June 1, 2020 were consecutively screened and divided into active HCMV infection group (20 cases) and non-active HCMV infection group (95 cases) based on whether a patient has active HCMV infection or not. Differences in demographic data, laboratory findings, and clinical outcomes were compared between the two groups. Moreover, logistic regression was applied to analyze risk factors for active HCMV infection.Results:The 20 of 115 patients with severe community-acquired pneumonia requiring respiratory support were confirmed to have active infection with HCMV, with a prevalence of active HCMV infection of 17.4%. The pneumonia severity index (PSI) and suppressor T lymphocytes (Ts) in active HCMV infection group were higher than that of the control group, and all the differences were statistically significant ( Z=2.432, P=0.015; Z=2.036, P=0.042); whereas lymphocytes, monocytes, blood lactate, and platelet levels were lower than those of the control group, and all the differences were statistically significant ( P < 0.05). Patients with active HCMV infection had a higher transfusion rate than the control group, and the differences were statistically significant (χ 2=3.941; P=0.047). Increasing levels of PSI and Ts percentage were independent risk factors for active HCMV infection ( OR=1.03, 95% CI: 1.01~1.05; OR=1.06, 95% CI: 1.00~1.11; P < 0.05). RICU length of stay, complication rates, and 90-day all-cause mortality were higher in the active HCMV infection group than the control group, and all the differences were statistically significant ( P < 0.05). Conclusions:Active HCMV infection is highly prevalent in patients with severe community-acquired pneumonia and associated with several adverse clinical outcomes, with PSI and Ts cell levels being independent risk factors.
