Epidemiological characteristics and trends of infectious diseases in Gansu province from 2015 to 2022
Objective This study analyzes infectious disease morbidity and mortality data in Gansu province from 2015 to 2022,aiming to comprehend the epidemiological characteristics and trends,as well as to determine prevention and control priorities.Methods We need Excel 2021 and JPR4.9 1.0 software to calculate morbidity ranks,mortality ranks,fatality rates,annual percentage change(APC)and annual average percentage change(A APC)in morbidity and morality rates of the infectious diseases.We also analyzed the trend in infectious diseases morbidity and mortality using the Toinpoint regression model.Results From 2015 to 2022,Gansu province reported 670 992 cases of infectious diseases and 1 127 deaths,with an incidence rate of 324.12 per 100 000 and a mortality rate of 0.54 per 100 000 cases.The top five diseases in morbidity were infectious diarrhea,tuberculosis,hepatitis B,influenza,and hand-foot-mouth disease;the top two in mortality were AIDS and tuberculosis.Morbidity(2019-2022)and mortality(2017-2022)showed a decreasing trend,with APC values of-16(-25.4,-5.3)and-9.1(-13.7,-1.2).No significant changes in the incidence or mortality trends were observed dur-ing the remaining periods.Ten diseases,including tuberculosis and hepatitis A,exhibited decreasing in-cidence,while acute hemorrhagic conjunctivitis showed an upward trend.Tuberculosis deaths declined,but AIDS-related deaths increased.Plague and rabies had the highest mortality rates.Conclusions In Gansu province,prevention and control efforts should focus on infectious diarrhea,tuberculosis,hepatitis B,influenza,and hand-foot-mouth disease.Special attention is needed for the high mortality risk of AIDS and plague,as well as the incidence of acute hemorrhagic conjunctivitis and brucellosis.
