标 题: 关于艾滋病：美国政府就是掩耳盗铃
发信站: BBS 未名空间站 (Sun Apr 27 10:00:34 2014, 美东)
看到一些人研究为什么某些地方艾滋病比例特别高（这也需要研究？），比如
washington DC. 各种搞笑理由都有，政客们还说是因为那里的水不好，就是没有人敢
说因为黑人多。看那个人作报告的时候，下面一堆人笑。这个政府是不是烂透了。 | l****z
发帖数: 29846 | 2 还有一个原因就是当地gay佬特别多. 现在新增艾滋病男性患者70%以上都是gay佬捅屁
眼捅出来的. 可笑我在其他版块发这个事实结果还被gay佬投诉要求删帖. 尼玛连事实
都接受不了?
为什么男同性恋性行为更容易传播艾滋病？
作者：杨杨
世界上报告的首例艾滋病患者就是一名美国男性同性恋者，目前美国73%的艾滋病病人
是同性恋或双性恋中的男子。中国发现的本土第一例因性接触感染艾滋病病毒的病人，
即是与多个男子有性关系的男人。
中国男同性恋者的艾滋病感染率约达1.35％。这一数字要比“男女性接触”的感染率高
出将近二十倍。
男性同性恋艾滋病感染率在中国艾滋病高危人群中居第二位，仅此于吸毒。为什么偏偏
是男性同性恋呢？
首先，男同性恋大多没有固定的性伴侣。“拥有多名性伴侣”往往是感染艾滋病或其他
性病的主要原因。
其次，男性同性性行为通常采取口交或肛交的方式，尤其是后者，大大加剧了男性同性
恋感染艾滋病的风险。直肠内的碱性环境很适宜于病毒的生存繁殖，而且肛肠的黏膜薄
而娇嫩，其下有丰富的毛细血管，发生性行为时极易引起破损出血，使病原体从肛门或
直肠的破损处侵入，直接进入血液。
事实上，即使有避孕套作为辅助，也不能全然避免病毒的感染。避孕套本身对于避孕这
一原始目的尚且存在一定的失败几率，何况与精子相比，无论从哪个角度考量，艾滋病
毒侵入对方的身体远比精子与卵子结合的几率大得多。
另外需要提及的是，由于器官构造特殊，男性在同性性行为过程中，往往需要借助润滑
剂。但其实，很多润滑剂由于含有凡士林一类的矿物油，反而容易导致乳胶变脆，极易
破裂，由此便又加大了艾滋病毒侵入人体的危险性。
1996年调查发现，北京艾滋病病毒感染者中，48%是男性同性接触者；1998年在已监测
过的男同性接触者中，2.5%已感染了艾滋病病毒，而这一数字在2001年已高达5.9%，可
见我国同性恋人群中艾滋病蔓延速度之快。
中国卫生部2010年11月份通报，截至今年10月底，中国累计报告艾滋病病毒感染者和病人
370393例，其中病人132440例；死亡68315例。
在中国艾滋病疫情新特点中，性传播已成为主要传播途径，男性同性性传播上升速
度明显。
通报称，截至2009年底，估计中国现存活艾滋病病毒感染者和病人约74万人，其中
病人约10.5万人。云南、广西、河南、四川、新疆和广东6省份累计报告感染者和病人
数占全国报告总数的77.1％。

Men are more affected by HIV and AIDS in the United States than women. In
2008 males accounted for 3 out of 4 AIDS diagnoses in the U.S.
The HIV transmission route leading to the most AIDS diagnosis in 2008 was
male-to-male sexual contact, followed by injection drug use and heterosexual
contact.
The U.S. Centers for Disease Control and Prevention (CDC) publish HIV
statistics for 37 states and 5 dependent areas with confidential name-based
HIV infection reporting. AIDS statistics include all 50 states and the
District of Columbia, as well as the 5 dependent areas.
HIV statistics
CDC statistics show that in 2007, 73% of persons living with a diagnosis of
HIV infection were male adults or adolescents.
Just over half of men diagnosed with HIV in 2008 became infected through
male-to-male sexual contact, around 30% of those diagnosed were infected
through heterosexual contact, and 10.5% through injecting drug use.
Between 2005 and 2008, annual HIV diagnoses increased among men who have sex
with men (MSM) and those who were exposed through heterosexual contact.
Infections decreased among IDUs and children. Of the 182 HIV diagnoses among
children in 2008, 141 were probably infected with HIV through mother-to-
child transmission.
Estimated adult and adolescent HIV diagnoses in 2008 by transmission route

Male-to-male sexual contact 22,810 - 22,472
Injection drug use 2,825 1,619 4,939

AIDS statistics
Adult and adolescent males accounted for 74% of people diagnosed with AIDS
in 2008. Between 2005 and 2008 the rate of AIDS diagnoses remained stable
among adult and adolescent males, but decreased slightly among females.
Between 2005 and 2008 the number of AIDS diagnoses increased among those who
were exposed through male-to-male sexual contact and decreased among those
exposed through injecting drug use.
Estimated adult and adolescent AIDS diagnoses in 2008 and cumulative
diagnoses since the beginning of the epidemic to end-2008, by transmission
