Analysis on type A and B notifiable diseases surveillance in Tianning district from 1973 to 2011

Objective : The author investigated the change and trend of notifiable category A B infectious diseases of Tianning District,Changzhou since 1973,which provides scientific basis for prevention and control work of infectious disease. Methods This paper uses descriptive epidemiology to analyze infectious diseases data of Tianning District from 1973 to 2011. Results The incidence of category A B infectious diseases of Tianning District has decreased obviously since 1973. The average disease rate in 1970s was 1782. 33 /100 000,during 2000 ~ 2003 reached the historical minimum of 192. 18 /100 000,and during 2004 ~ 2011 was 309. 96 /100 000. The spectrum of infectious diseases changed dramatically. In 1970s,intestines disease took the predominance,while during 2000 ~ 2011 hematology,sex and respiratory infectious diseases took the predominance. Natural focus and insect- borne infectious diseases kept the low disease rate since 1990s. Planned immunization diseases decreased from 255. 57 /100 000 to 49. 33 /100 000. Compared to 2000 ~ 2003,infectious diseases during 2004 ~ 2011 has similar constituent ratio and obviously ascendant disease rate,which has statistical significance. Conclusions During 1973 ~ 2011,Tianning District adopted measures of vaccination,health education,sanitary condition improvement,disease surveillance enhancement and epidemic treatment standardization,which have taken clear effects of prevention and control of infectious diseases. However,the epidemical status indicates that the prevention and control of infectious diseases face various threats. We should pay more attention and seek new way out.
