RESUMO
Objective To analyze the epidemiological characteristics of syphilis in Jiading District of Shanghai from 2014 to 2018, and to provide a scientific basis for the development of future syphilis prevention and control work. Methods According to the date of onset, all syphilis cases in the infectious disease report information management system from 2014 to 2018, and their epidemic characteristics were analyzed using descriptive epidemiological methods. Results A total of 2 992 cases of syphilis were reported in Jiading District from 2014 to 2018, with an average annual incidence of 38.89/100 000. The overall incidence showed a downward trend year by year. Recessive syphilis was the main cause, and the incidence increased year by year. Fetal syphilis was relatively small and the incidence decreased year by year. The composition ratios of recessive syphilis, primary syphilis, secondary syphilis, and tertiary syphilis in different years were significantly different, and the differences were statistically significant (χ2=26.955, P2=17.793, P=0.0012=12.701, P=0.0130.05). 20~39 years old had the highest incidence rate of syphilis. The areas with high incidence were mainly concentrated in the old urban area of Jiading Center and areas with high population density. The occupational distribution was mainly concentrated in young and middle-aged household workers and unemployed people, workers and elderly retirees. Conclusion In recent years, the syphilis epidemic in Jiading District of Shanghai has shown a downward trend. However, the situation of prevention and control was still severe. It is necessary to continue to improve the level of syphilis detection, and to detect and treat syphilis early. Meanwhile, it is important to strengthen publicity and education in key areas and key populations, and increase awareness of disease prevention to reduce the incidence of syphilis.
RESUMO
Objective To analyze the incidence and epidemic characteristics of Class A and B infectious diseases in Jiading District of Shanghai from 2014 to 2019，understand the prevention and control effects of infectious diseases in recent years，and provide a reference for the formulation of future prevention and control strategies and measures for infectious diseases． Methods According to the " China Disease Prevention and Control Information System"，statistical analysis was conducted on the data of Class A and B infectious diseases in Jiading District of Shanghai from 2014 to 2019． Results A total of 11 862 cases of Class A and B infectious diseases were reported in Jiading District of Shanghai from 2014 to 2019，with an average annual incidence rate of 127.34/100000． The overall reported incidence rate showed a downward trend (χ2=36.354，P =0.0002=818.269，P=0.000<0.05) ．The high incidence age was 5- years old， followed by 20- years old. The top three occupations in terms of morbidity were workers, housework, unemployed，and retired．In terms of onset time，December and May-June were the two peak periods; February was the trough．Conclusion Class A and B infectious diseases in Jiading District of Shanghai showed a downward trend from 2014to 2019． Blood-borne and sexually transmitted infections and respiratory infectious diseases are still infectious diseases that need to be focused on prevention and control，mainly syphilis，gonorrhea and tuberculosis. Targeted prevention measures should be formulated in conjunction with peak onset times and key populations to further reduce the incidence of Class A and B infectious diseases．
