其实每天刷牙都会有出血的，这个并不少见，有些人还尤其容易出血。

I heard the virus will die in a few second in the air. Anyone can confirm this?

这个不像是真的

不是民科，已经是有科学调查显示的。可能是包皮里环境更温暖、舒适，病毒在里面存活时间更长。

HIV in the Environment

Scientists and medical authorities agree that HIV does not survive well in the environment, making the possibility of environmental transmission remote. HIV is found in varying concentrations or amounts in blood, semen, vaginal fluid, breast milk, saliva, and tears. (See below, Saliva, Tears, and Sweat.) In order to obtain data on the survival of HIV, laboratory studies have required the use of artificially high concentrations of laboratory-grown virus. Although these unnatural concentrations of HIV can be kept alive under precisely controlled and limited laboratory conditions, CDC studies have showned that drying of even these high concentrations of HIV reduces the number of infectious viruses by 90 to 99 percent within several hours. Since the HIV concentrations used in laboratory studies are much higher than those actually found in blood or other specimens, drying of HIV- infected human blood or other body fluids reduces the theoretical risk of environmental transmission to that which has been observed--essentially zero.

Incorrect interpretation of conclusions drawn from laboratory studies have alarmed people unnecessarily. Results from laboratory studies should not be used to determine specific personal risk of infection because 1) the amount of virus studied is not found in human specimens or anyplace else in nature, and 2) no one has been identified with HIV due to contact with an environmental surface; Additionally, since HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions, it does not spread or maintain infectiousness outside its host.

HIV is sensitive to fluctuations in temperature and the presence of oxygen. One place that HIV has been know to survive in is drug injection syringes since these are airtight and often contain blood from the injector.

包皮，我们中国人讲藏污纳垢，其实是有道理的，各种病毒病菌传播因为包皮传播更方便，那个和宫颈癌的有关的病毒也是如此，很多性传播疾病是男性隐性携带，不发病，女的倒霉，犹太人割礼算是对女性功德无量。

各种体液，血液是最强的病原载体吧，男同不安全性交容易传播艾滋病毒，我觉得那个受伤（就算是微小创伤）导致的流血比那个精液更利于病毒传播吧。

没看出来这个贴子和标题有什么联系。

顺便问一句，感染了AIDS那么快就能查出来？

这难道有共用的?
