Results The total effective rate in observation group was 96.4%, which was significantly higher than that in control group (63.6%, P <0.01). The observation group antipyretic time, antidiarrheal time, hospitalization time were shorter than the control group (P <0.05). The negative rate of viral antigen in the observation group was 90.9%, which was higher than that in the control group (58.2%, P <0.05). Conclusion Reveduning injection for the treatment of infantile viral enteritis can shorten the course of disease and hospital stay, the effect is superior to conventional treatment.
