Epidemic characteristics and trends of notifiable infectious diseases among the elderly aged 60 and over in Haidian District of Beijing from 2005 to 2021
Objective To analyze the trends and characteristics of notifiable infectious diseases among people ≥60 years old in Haidian District of Beijing,from 2005 to 2021,and to provide references for the prevention and control of these diseases. Methods Descriptive methods,Permutation test and Rank sum test were used to analyze the epidemiologic features of diseases. Joinpoint Regression (JPR)was employed to calculate the annual percent change (APC) and average annual percent change (AAPC) for Category B and Category C infectious diseases and major infectious diseases. Results From 2005 to 2021,the reported incidence of Category B and C infectious diseases among the elderly population in Haidian District of Beijing was 437.02/100000,the reported mortality was 2.38/100000,and the reported case fatality rate was 0.54％;The reported mortality and case fatality rate of Category B infectious diseases were higher than those of Category C infectious diseases (P<0.01). The incidence,mortality and case fatality rate of Category B infectious diseases in the male elderly were higher than those in the female (P<0.01);The ≥80 year old group had the highest incidences of Category B and Category C infectious diseases and the highest mortality rate of Category B infectious diseases (P<0.05);The AAPCs corresponding to the reported incidence and mortality of Category B infectious diseases were-7.20 (t=-7.802,P=0.000) and-5.31 (t=-3.063,P=0.008) respectively. The six notifiable infectious diseases with top reported incidences were other infectious diarrhea diseases (147.90/100000),influenza (82.32/100000),dysentery (71.04/100000),tuberculosis (54.56/100000),recessive syphilis (25.43/100000) and hepatitis B (22.91/100000). The incidence AAPCs of dysentery,hepatitis B and other infectious diarrhea diseases were-12.79 (t=-21.772,P=0.000),-14.16 (t=-4.672,P=0.000) and-10.61 (t=-10.744,P=0.000),respectively;The incidence AAPCs of pulmonary tuberculosis and influenza were 1.15 (t=2.977,P=0.009) and 38.36 (t=4.093,P=0.000),respectively. The overall age-standardized incidences of pulmonary tuberculosis,recessive syphilis,hepatitis B,other infectious diarrhea and influenza in the elderly male were higher than those in the female. Conclusions The incidence and mortality of Category B infectious diseases among the elderly population in Haidian District of Beijing showed a downward trend. Tuberculosis and influenza were the key infectious diseases to be prevented and controlled among elderly population. The prevalence of pulmonary tuberculosis and hepatitis B in the male elderly population shouldn't be ignored.
