ABSTRACT
Objective@#To analyze the epidemiological characteristics of newly diagnosed HIV/AIDS cases aged 50 years or over in Zhejiang Province from 2015 to 2019, so as to provide reference for the development of prevention and control strategies.@*Methods @#The data of newly diagnosed HIV/AIDS cases in Zhejiang Province were collected through the China HIV/AIDS Comprehensive Response Information Management System, and the demographic characteristics, infection routes,regional distribution and time distribution of the cases were analyzed. @*Results@#A total of 6 726 HIV/AIDS patients were recruited in this study, and the number of new patients from 2015 to 2019 showed an increasing trend ( P <0.05 ) . The number of participants diagnosed at the age of 50-59, 60-69 and 70-91 years old were 3 433( 51.04% ), 2 242 ( 33.33% ) and 1 051 ( 15.63% ). The majority of them were males ( 5 180, 77.01% ) , married ( 4 286, 63.72% ) , Zhejiang residents ( 5 304, 78.86% ) , and lived in rural areas ( 4 095, 60.88% ) . In terms of exposure history,6 586 cases ( 97.92% ) were infected by sexual contact. Among the 5 083 males infected by sexual contact, 82.63% were through heterosexual contact, 94.79% had extramarital sex partners, among whom 76.61% were commercial sex partners. The married women patients who confirmed HIV positive accounted for 75.44%. There were increasing trends in the proportion of the cases living in rural areas, male cases infected through heterosexual contact and those with extramarital and commercial sex partners, and female cases with their husbands positive along with age ( P <0.05 ) . @*Conclusions@#The number of newly diagnosed HIV/AIDS cases aged ≥50 years is increasing in Zhejiang Province. Many of them live in rural areas. Commercial sexual contact is the main route of HIV transmission among males and further lead to HIV transmission within couples.
ABSTRACT
Objective@#To evaluate the third round of Zhejiang Comprehensive AIDS Response (CARES) program (nine national areas and three provincial areas) and the control effect of AIDS, so as to provide reference for AIDS prevention and control. @*Methods@#According to the final assessment protocol of the third round of China CARES, the data of 23 assessment items which were collected from online database and field investigation for 12 response areas of Zhejiang in 2014 and 2018 were evaluated. The endemic situation and detection of AIDS in CARES areas was compared with those in non-CARES areas, in order to evaluate the achievement of Zhejiang CARES areas.@*Results@#The rates of reaching the standard ranged from 91.30% to 100.00% in 12 CARES areas. Six indexes in leadership and innovation, fifteen (seventeen in total) indexes in HIV/AIDS control and prevention reached the standard. The items that failed included the awareness rates of AIDS and indicators in “prevention and intervention”. The rates of of reaching the standard in “publicity and education”, “monitoring and testing”, “prevention and intervention”, and “treatment and follow-up” increased from 55.56%, 79.17%, 79.76% and 65.00% in 2014 to 91.67%, 100.00%, 90.48% and 100.00% in 2018, respectively. The proportion of HIV testing people in permanent residents was 30.94% in CARES areas in 2018, which was significantly higher than 20.70% in non-CARES areas (P<0.05). The proportion of new reported HIV/AIDS in CARES areas was 50.87%, and the average increase was 4.48%, which was lower than 9.95% in non-CARES areas.@*Conclusion@#The third round of Zhejiang CARES program has remarkable achievement and plays a positive role in the prevention and control of AIDS.
