看到有個網頁說
美國疾管局公佈了2008年全國21個大城市的男同性間性行為者
(Men who have sex with men ,簡稱MSM)HIV盛行率調查,
發現全國MSM的HIV盛行率是19%。
然後我google找到這個pdf檔 https://goo.gl/eqagff
The median HIV prevalence among gay men and other men who
have sex with men is 19% in western and central Africa and 13%
in eastern and southern Africa.
所以美國真的每5個男同志就有1個有愛滋病嗎
有沒有八卦
