Through forty years' sustained efforts in the prevention and treatment of malaria in Zhejiang Province, the malaria incidence dropped from 76. 65k in the Fifties to 0. 91 in the Eighties. Three malaria epidemics emerged in 1954 ,1962 and 1973, respectively, among them the epidemic in 1962 was the most serious one with 0. 88 million cases reported and an incidence of 330. The annual incidence of the overall counties/cities was below 1 after 1988. Only 172 malaria cases were found in 1992, the incidence being 0. 04. No indigenous malaria case was found in 38 counties in 1992, accounting to 43. 7% of the total malaria endemic counties. The number of imported malara cases was 3 829, amounting to 89. 2 % of the total number of cases. Through the spot-check of the Ministry of Public Health in 1993, it was confirmed that the criteria of basic elimination of malaria in the province was attained.

Objective: To investigate the factors affecting HIV testing among male college students with sexual behaviors, so as to provide the evidence for improving the detection of HIV testing among young college students. Methods: Four undergraduate universities and one junior college were randomly sampled from Hangzhou City using a purposive sampling method during the period between September and November, 2021, and male students with self-reported sexual behaviors were recruited as study students. Participants' demographics, AIDS-related knowledge, sexual behaviors and HIV testing were collected using questionnaires, and factors affecting HIV testing using a multivariable logistic regression model. Results: A total of 720 male college students with sexual behaviors were enrolled, including 180 freshmen (25.00%), 178 sophomores (24.72%), 163 juniors (22.64%), 50 seniors (6.94%) and 149 postgraduates (20.69%), and 94 students received HIV testing (13.06%), including 57.45% receiving self-testing. Multivariable logistic regression analysis identified postgraduates (OR=0.302, 95%CI: 0.127-0.719), sexual orientation (homosexual, OR=0.090, 95%CI: 0.028-0.294; bisexual/uncertain, OR=0.181, 95%CI: 0.066-0.495), awareness of HIV testing (low awareness, OR=0.411, 95%CI: 0.176-0.957; moderate awareness, OR=0.305, 95%CI: 0.123-0.757; high awareness, OR=0.087, 95%CI: 0.032-0.235) as factors affecting HIV testing among male college students with sexual behaviors. Conclusions The prevalence of HIV testing correlates with awareness of HIV testing among male college students with sexual behaviors. Improvements in health education of HIV testing and accessibility of HIV testing services are recommended.

Objective : To investigate the factors affecting multiple sexual partner behaviors among men who have sex with men (MSM) at ages of 16 to 24 years in Zhejiang Province, so as to provide the evidence for formulating the integrated interventions for HIV/AIDS among adolescents. Methods : The demographic features, sexual behaviors and HIV testing were collected from MSM at ages of 16 to 24 years in Zhejiang Province through the Management Information System of China AIDS Fund for Non-governmental Organizations (CAFNGO) in 2021. The factors affecting multiple sexual partner behaviors were identified among MSM at ages of 16 to 24 years using a multivariable logistic regression model. Results : A total of 1 253 participants were enrolled, with a mean age of (21.16±2.06) years. There were 1 219 unmarried respondents (97.29%), 807 (64.61%) with diploma and above, 250 (19.95%) with multiple sexual partners during the past 3 months, 344 (27.45%) with unprotected sexual behaviors in the past 3 months, 71 (5.67%) that had used rush or new drugs, 511 (40.78%) that were unaware of their sexual partners' HIV infections, 28 (2.23%) with symptoms or diagnosis of sexually transmitted diseases, and 35 (2.79%) with positive HIV testing. Multivariable logistic regression analysis identified age (19 years-, OR=2.563, 95%CI: 1.404-4.679; 22 to 24 years, OR=2.149, 95%CI: 1.180-3.913), having unprotected sexual behaviors in the past 3 months (OR=5.338, 95%CI: 3.938-7.237), having used rush or new drugs in the past 3 months (OR=3.669, 95%CI: 2.142-6.286), unaware of sexual partners' HIV infections(OR=1.402, 95%CI: 1.032-1.903), and positive HIV tests (OR=2.763, 95%CI: 1.298-5.880) as factors affecting multiple sexual behaviors among MSM at ages of 16 to 24 years. Conclusions The multiple sexual behaviors correlate with age, unprotected sexual behaviors, use of rush or new drugs and unawareness of sexual partners' HIV infections among MSM at ages of 16 to 24 years.

Objective To identify the status and risky factors of anal sexual intention in casual sex behavior in Zhejiang province. Methods Stratified cluster sampling was conducted among college students in 13 colleges in 11 cities between October to November, 2018. 482 students were enrolled who self?reported"heterosexuality"and"ever had casual sex behavior". A self?designed network questionnaire was complimented containing basic information, knowledge of HIV, sexual behavior. Chi?square test was used to compared the difference of anal sex intention between different characteristic. The multivariate logistic regression methods was used to analyze the influence factors. Results Among 482 students, the age was (20±1.442) years old. And 87.3% (421) were male and 29.0% (140) were from other province. The rate of anal sex intention were 19.4% (94/482) in total, with the rates of 38.1% (24/63) and 14.4% (53/367) in students with sexual number more than 5 and less than 5 (P<0.001), separately. Compared with students searching casual sexual partner with non?internet access (17.0%, 16/201), students searching sexual partner with internet access had higher risk of anal sex practice (27.8%, 78/281) (P<0.001). The rate of anal sex practice among students reporting"ever had casual sex after drinking"and"never had casual sex after drinking"were 30.5% (64/210) and 9.4% (25/266) (P<0.001). The multivariate logistic regression results revealed that compared with students searching casual sexual partner with non?internet access and reporting"never had casual sex after drinking", subjects searching sexual partner with internet access ( OR (95%CI )=2.65 (1.34-5.23)) and "ever had casual sex after drinking" OR (95%CI )=3.02 (1.65-5.33) were more likely had higher risk of anal sex practice. Conclusion Heterosexual college students in Zhejiang Province tend to have anal intercourse with causal sexual partners. Searching for causal sexual partners on internet or mobile phone dating software and having temporary sexual behavior after drinking were correlated factors.

Objective: To investigate the characteristics of temporary heterosexual behaviors among male college students through Internet dating, so as to provide insights into HIV/AIDS control among young college students. Methods: A total of 15 universities/colleges were sampled from Zhejiang Province using a stratified cluster sampling method, and 3 schools/departments were sampled from each university/college. Male college students with temporary heterosexual behaviors during the past year were recruited. Participants' demographics, AIDS-related knowledge, compliance to HIV/AIDS interventions, Internet dating and sexual behaviors were collected, and the characteristics of male college students with Internet dating were analyzed. Results : A total of 326 students were enrolled, including 202 participants from regular institutions of higher education (61.96%) and 124 students from higher vocational colleges (38.04%). There were 79 freshmen (24.23%), 99 sophomores (30.37%), 104 juniors (31.90%) and 44 seniors (13.50%), and there were 100 participants (30.67%) with temporary heterosexual behaviors through Internet dating during the past year. Among the 100 participants, there were 75.00% of participants knowing “man who have sex with man is the main transmission pattern of AIDS among young students in China”, 93.00% knowing “insisting on accurate use of condoms may reduce the risk of HIV infections and transmission” and 93.00% knowing “seeking HIV testing and counseling actively following high-risk behaviors”. There were 77 participants (77.00%) with students as their temporary heterosexual partners, 17 participants (17.00%) that had received HIV self-testing and 17 participants (17.00%) that had received HIV testing in medical institutions, 22 participants (22.00%) that had never used condoms during temporary heterosexual behaviors during the past year, and 29 participants (29.00%) with commercial sexual behaviors during the past year. In addition, male college students with temporary heterosexual behaviors through Internet dating were more unlikely to use condoms and more likely to have commercial sexual behaviors than those with dating through other ways (P<0.05). Conclusions Male college students with temporary heterosexual behaviors through Internet dating are more likely to have high-risk sexual behaviors than those with dating through other ways. Internet-based mobile sexual education and HIV/AIDS health education are recommended.

Objective : To analyze the problems in the AIDS control strategy in key areas of Zhejiang Province, so as to provide insights into the improvement of the control strategy. Methods : The AIDS control data were collected from 10 key counties (districts) in Zhejiang Province, and the AIDS control strategy was comprehensively evaluated using a SWOT analysis. Results : The strengths of the AIDS control strategy in key counties (districts) of Zhejiang Province included distinct working objectives, well-organized leadership, and effective control measures, the weaknesses included large number of HIV-infected cases, high burden of disease, difficulty in management of AIDS transmission and insufficient AIDS control capability, and the opportunities included the AIDS control in key counties (districts) conforming to the current status of AIDS control, strong support of innovative strategies and technical support from professional teams, while the threats included insufficient working mechanisms for AIDS control, the gap between the effectiveness of AIDS control and the target goal and unverified scientific evidence of the control strategy. Supported policies should be fully used, working mechanisms need to be improved, control strategies need to be innovated, and assessments need to be implemented for AIDS control in key counties (districts). Conclusions There are both opportunities and challenges for AIDS control in key counties (districts) of Zhejiang Province. Optimization of the working mechanisms, promotion of precision interventions, and search for repeatable control strategy in other disease-affected regions are required for AIDS control.

Objective: To study oral sexual behavior and related factors among male students. Methods: The male students from college graduation in Hangzhou were selected as the study objects, and the inclusion criteria were having had sex and informed the type of behavior. A total of 490 subjects were finally included. Results: Among 490 male students, the 20-22 years old, 23 years old and 24-27 years old age groups accounted for 38.8% (n=190), 37.8% (n=185) and 23.3% (n=114), respectively. A total of 99 (20.2%) cases had oral sexual behavior, of which only 14 (2.9%) cases used condom. After adjusting for unplanned pregnancy, stage of sexual behavior, sexually transmitted diseases infection possibility, sexual orientation factors, normal/unnormal family relationship, more than 2 sexual partners, casual sexual partners, sexual partners from other college, sexual partners from society, sexual behavior in past 1 year were positively associated with oral sexual behavior. The corresponding OR (95%CI) values were 2.77 (1.40-5.50), 2.29 (1.27-4.15), 2.68 (1.23-5.88), 2.45 (1.34-4.48), 2.47 (1.15-5.33) and 2.04 (1.05-3.96), respectively. Use of condoms was negatively associated with oral sexual behavior, the OR (95%CI) value was 0.20 (0.09-0.42). Conclusion Normal/unnormal family relationship, more than two sexual partners, casual sexual partners, sexual partners from other college, sexual partners from society, sexual behavior in last one year and condom use in each vaginal sexual behavior were associated with oral sexual behavior.
