Abstract:
Objective To investigate the epidemiological characteristics of acquired immune deficiency syndrome (AIDS) in Shandong Province,and to provide scientific evidence for formulating prevention and control strategy and carrying out effective measures.Methods Epidemiological data of reported human immunodeficiency virus (HIV) infection and AIDS cases (HIV/AIDS) in Shandong Province from 1992 to 2011 were analyzed.Results A total of 4313 cases of HIV/AIDS were confirmed and reported by the end of 2011,with an average incidence of 2.39 parts per million (ppm) annually.An upward trend was showed for annual reported incidence.The top 5 cities of incidence were Ji'nan,Qingdao,Zibo,Weifang and Weihai,which were 5.72 ppm,4.39 ppm,3.29 ppm,3.10 ppm and 3.02 ppm,respectively.The average annual reported incidence was 3.74 ppm for male,which was significantly higher than that for female (1.39 ppm; x2 =743.96,P＜0.05).The reported incidence was highest among 20-29 age group (5.56 ppm),with 57.18％ of homosexual transmission.The proportion of homosexual transmission in annual reported cases increased from 1.82％ in 2004 to 37.49％ in 2011.Conclusions The epidemic situation of AIDS in Shandong Province is severe,with unbalanced geographical distribution.Sexual transmission is the main route of transmission,and cases of homosexual transmission increase sharply.
