Abstract:
Objective The study was conducted to investigate the epidemiological characteristics of infectious diseases in Suichang county,Zhejiang province.Methods Based on the descriptive epidemiological method,the data on the incidence and death of Class A and B notifiable infectious diseases in Suichang from 1990 to 2006 were systematically analyzed.Results A total 14 328 of cases that contained 18 kinds of Class A and B infectious disease were reported during the 17 years,with an annual incidence rate of 373.90/lakh and a death rate of 0.84/lakh.The total death rate was 0.22%.The top five diseases in terms of their incidence rates were hepatitis B,bacillary dysentery,tuberculosis,gonorrhea and hepatitis A.Infectious diseases to which immunity strategies had been implemented and those with a natural infectious focus or insect-borne ones demonstrated a sharp decrease in the incidence rate.In the recent decade,infectious diseases such as bacillary dysentery,tuberculosis had relatively stable incidence rates,whereas blood-borne and sexually transmitted diseases demonstrated an increasing tendency.Conclusion Immunization is the most effective way in controlling infectious diseases.The improvement of living conditions can help reduce insect-borne infectious diseases or those with natural infectious foci.
