- Abstract: OBJECTIVE: To study the pathogenic spectrum and the clinical characteristics of viral diarrhea in children.METHODS: The study was conducted in 400 children with viral diarrhea hospitalized in Children's Hospital from January to December in 2016. The stool specimens(about 5 mL)were collected for detection from the children on the day of hospitalization. The ELISA method and PCR method were used to detect the genotypes of HUCV,HADV,HAsta V and HRV in stool specimens,and the clinical data of children were collected at the same time. RESULTS: In 2016,the total positive rate of HRV,HUCV,EAd V and HAst V in the stool specimens of children with viral diarrhea was 59%(236 cases). The positive detection rates of the four viruses were 178 cases(75.42%),68 cases(28.81%),12 cases(5.08%)and 5 cases(2.12%)respectively,of which 11.42% were double mixed infection and 41% were of unknown pathogens. The HRVG6(93.63%,147 cases)and P3(91.08%)as well as G6[P3](90.45%)combination were the popular superior type in 2016,and about 11.79%couldn't be typed. Norovirus accounted for 92.65% of the calicivirus viruses,and GⅡ accounted for 98.41%. About 81.79%of the children(193 cases)hospitalized for viral diarrhea were less than 24 months old. Pathogens were different at different peak age. The peak season of onset was fromJanuary to March and December. The main clinical manifestations were diarrhea,vomiting and fever. CONCLUSION: It is essential to determine the unknown pathogens and improve the pathogenic spectrum in children with viral diarrhea. Viral diarrhea is often accompanied by extraintestinal clinical manifestations.
