Objective: To investigate the pathogenic characteristics of viral encephalitis in children living in Hebei province. Methods: We randomly collected cerebrospinal fluid specimens from a total of 399 children diagnosed with viral encephalitis in Hebei Children′s Hospital from May to December 2017. Real-time fluorescence quantitative PCR and Sanger sequencing were used to detect viral nucleic acids in cerebrospinal fluid by an automatic laboratory station. Statistical analysis was performed on the experimental data using SPSS 21.0 software and the clinical data were analyzed. Comparison of infection rates of EV encephalitis in different months, using line × column chi-square test. The MRI and EEG positive rates of different viral encephalitis and viral encephalitis patients not infected with the virus were analyzed by Fisher′s exact probability test. The positive rate of infection with different viruses and non-virus agents was analyzed by Fisher′s exact probability test. Results: The result showed that 80 of 399 samples were positive, and the positive rate was 20.05%. It included 22 cases of enterovirus, 4 cases of influenza A virus, 3 cases of mumps virus, 2 cases of herpes simplex virus type 1, 1 case of herpes simplex virus type 2, 4 cases of EB virus, 7 cases of cytomegalovirus, 7 cases of herpes zoster virus, 8 cases of adenovirus, 14 cases of human herpesvirus type 6. Eight cases had combined viral infection. Eight cases had concurrent infections: 3 cases had enterovirus and herpesvirus type 6 concurrent infection, 1 case had enterovirus and Japanese encephalitis virus concurrent infection and 1 case had herpes simplex virus type 2 and adenovirus, 1 case had influenza A virus herpesvirus type 6, 1 case had mumps virus and herpesvirus type 6, 1 case had mumps virus and herpesvirus type 6, 1 case had herpes simplex virus type 1 and herpes zoster virus concurrent infections. Children with EV viral encephalitis in Hebei Province were highly prevalent in May and June (P=0.016). HHV6 virus encephalitis was more susceptible to infection than non-HHV6 virus (P=0.016); The rate of MRI positive findings in patients with different viral encephalitis was not statistically significant (P>0.05). The result of EEG of different viral encephalitis were P>0.05, which was not statistically significant. Conclusions EV was the most common pathogen of children with viral encephalitis in Hebei province. Encephalitis caused by influenza A virus cannot be ignored in clinical practice.
