【摘要】：为探究新媒体时代,宣传教育对艾滋病在MSM(男男性行为接触者)群体中的防控效果,在建立一类MSM群体艾滋病传播模型的基础上引入媒体因子,并针对这类模型进行理论分析.通过模型计算,得出在无媒体干预下,MSM群体艾滋病传播的基本再生数R0=4.59;在不同措施中,宣传安全套的使用比其他宣传策略更加有效,且提高与固定性伴安全套使用率对R0影响更大.同时,得出MSM人群中有36.7%的艾滋病感染者未被发现,而每年新增感染者中有51.3%是被这些没有被发现的感染者所传染,利用新媒体加强对MSM群体艾滋病预防的宣传教育可有效控制HIV的进一步蔓延.
[Abstract]:In order to explore the effect of propaganda and education on the prevention and control of AIDS in MSM (men who have sex with men) in the new media era, the media factors were introduced on the basis of the establishment of a class of HIV / AIDS transmission models among MSM groups, and the theoretical analysis was carried out on these models. Through the model calculation, the basic reproduction number of HIV / AIDS transmission in MSM population without media intervention was found to be R0 / 4.59. In different measures, condom use was more effective than other propaganda strategies. And increased condom use with fixed partners had a greater impact on R0. At the same time, it is concluded that 36.7% of the MSM population has not been found, and 51.3% of the new HIV infections are infected by these undetected people every year. The use of new media to strengthen the MSM community AIDS prevention publicity and education can effectively control the further spread of HIV.
