Abstract:
[Objective] To investigate the pathogen spectrum and characteristics of diarrheal disea-ses among children under five and to provide the basis for prevention and control measures . [ Methods] From February 2012 to January 2013, a total of 619 cases from 2 sentinel hospitals were collected for case survey .From them were collected stool specimens for detection of enteric pathogenic bacteria and virus nu-cleic acids. [Results] The virus detection rate was norovirus (11.95%), rotavirus(7.27%), enteric adenovirus(2.91%), saporovirus(1.45%) and astrovirus(0.97%).The bacteria detection rate was E. coli(5.65%), nontyphoidal salmonella (2.42%), campylobacter (0.81%), aeromonas hydrophila (0.65%),shigella(0.48%) and yersinia enterocolitica (0.32%).The virus detection rate was 27.70%from August to next March, which showed higher than that of other months (18.48%) (χ2 =7.18,P <0.05).The bacteria detection rate was 15.34%from April to October, showing higher than the rate of oth-er months(3.15%)(χ2 =31.22,P<0.05). [Conclusion] Norovirus is the main pathogen for viral diarrheal diseases in children under five and E .coli is the main pathogen of bacterial diarrheal diseases . All study results suggested that summer and autumn should be as the focus time in prevention and control of bacterial diarrhea , while those of viral diarrhea should cover the whole year .
