Abstract

Abstract

Objective To understand pathogenic distribution and epidemiological characteristics of diarrhea syndrome in Gansu Province. Methods Fecal specimens from diarrhea syndrome surveillance cases at sentinel hospitals in Gansu Province from 2009 to 2018 were collected, and virus nucleic acids were detected by real-time fluorescent chain reaction, and bacteria were detected by isolation culture. Results 1 547 positive cases were detected from 4 406 stool specimens with the positive rate of 35.11%. Among the positive samples, 1 281 cases were positive for virus with the positive rate of 47.20%; 287 cases were positive for bacteria with the positive rate of 8.57%. Top five of pathogenic spectrum were rotavirus(46.04%), astrovirus(13.37%), norovirus(13.15%), Shigella(9.90%) and adenovirus(7.81%). In different age groups, statistically significant differences were found in the positive rates of rotavirus, norovirus, astrovirus, Shigella and non-typhoid Salmonella(all P < 0.05). The positive rate of virus was higher from November to March of next year, and the positive rate of bacteria was higher from June to August. The epidemic seasons of pathogens were different, of which rotavirus was dominating in four seasons. Conclusions The pathogenic spectrum of diarrhea is wide relatively in Gansu Province, and viral diarrhea is more common, with obvious seasonal peak. Continuous monitoring should be strengthened to grasp characteristics and epidemic trends of pathogens, and it is helpful to take targeted and seasonal preventive measures in population at high risk.
