Abstract

Abstract

Objective To explore the incidence trend and epidemic features of type A and B intestinal infectious diseases, and to provide scientific basis for prevention and control. Methods Data of type A and B intestinal infectious diseases reported in Xinghua from 1990 to 2019 were analyzed by descriptive epidemiology. Results A total of 30 282 cases with 7 categories of type A and B intestinal infectious diseases were reported in Xinghua from 1990 to 2019.The average annual incidence was 69.66 per 100 000 population. The incidence showed a decreasing trends (x²=56 574.719, P < 0.001) with 161.30 per 100 000, 21.29 per 100 000, and 18. 35 per 100 000 in the 1990-1999, 2000-2009, and 2010-2019 periods respectively.The main distribution of cases were hepatitis A and typhoid and paratyphoid in 1990-1999, unclassified hepatitis and hepatitis A in 2000-2009, and unclassified hepatitis and hepatitis E in 2010-2019. The constituent ratio was 78.58%, 65.87% and 69.81%, respectively. There were significant differences with the sex and ages between three decades. Additionally, the cases in rural and urban areas accounted for 74.35% and 25.65% while the majority of patients were farmers, students, scattered children and workers. The incidence peaked in March and July to October in 1990-1999 and 2000-2009, exhibiting a double peak distribution, while the seasonality of 2010-2019 was not obvious. Conclusions The effects were notable in category A and B intestinal infectious diseases control and prevention with the incidence rates have declined significantly in Xinghua City from 1990 to 2019. Therefore, it is essential to strengthen the supervision of intestinal infectious disease in rural areas as well as farmers, students, scattered children and the elderly. Combined with the characteristics of A and B intestinal infectious diseases in the new era, comprehensive prevention and control measures should be taken to reduce the incidence rate.
