ABSTRACT
Objective To investigate the infection situation of group A human rotavirus(HRV)among the infants and young children with diarrhea in Lanzhou city,and to observe the relation between genders and age with the viral positive rate.Methods 2 378 samples of feces in the infants and young children with diarrhea were collected in this hospital from January to December 2013.The group A HRV antigen in samples was detected by using the immunochromatographic sandwich method.The positive rates of group A HRV infection in different months were analyzed and compared with the bacterial diarrhea;the viral positive rates in different genders and ages were analyzed.Results Among 2 378 detected feces samples,the average positive rate of group A HRV was 24.1% and the highest was 39.8% during the months from October to December;the average positive rate of bacterial diarrhea was 28.2% and the highest was 38.2% during the months from July to September.The positive rate of group A HRV was 25.5% in male children patients and 22.6% in female children patients,but the difference was not statistically significant (P >0. 05).The differences in the positive rates of group A HRV among different ages had statistical significance (P <0.05).The average positive rate was highest(29.0%)in children patients aged less than 2 years old,followed by the children patients aged 2 - <4 years old,which was 21.6%.Conclusion The group A HRV has the higher infection positive rate in winter and early spring,which mainly focuses on the children patients aged less than 2 years old.
