这个。。也是传说吧，艾滋不可能体外感染。。还唾液里的血丝。。沾到空气就幻灭了，更别谈在唾液里。
幻灭不太可能吧，否则唾液在口腔里和在空气中有何区别？口腔难道是封闭的？

这个是美国官方CDC的说法。。冷笑什么。。
理论上来说的吧？
单纯的这个病毒遇到空气会幻灭，这个可以信
感染血液暴露在空气中能否幻灭？

口腔里，根本没有艾滋病毒（又说1ML只有1个），酶的特性，学过吧？在空气中立刻失活的HIV，在酶的作用下，你觉得是什么样的结果？Results from laboratory studies should not be used to assess specific personal risk of infection because (1) the amount of virus studied is not found in human specimens or elsewhere in nature, and (2) no one has been identified as infected with HIV due to contact with an environmental surface. Additionally, 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; therefore, it does not spread or maintain infectiousness outside its host.

我两周就严重盗汗，被子全湿，每晚要翻几次被子。这下更恐了。
游离于体外的病毒接触空气是可以立即灭活的，但是含有病毒的体液，在量较多的时候，干涸后，才会失去感染性，其实研究这个真没什么意义，因为没人能具体量化病毒。但是可以肯定的是，干涸的体液，肉眼不可见的体液，是没有可能导致感染的。另外，单独的游离于体外的病毒更不需要考虑，那得需要专业的仪器设备才能分离
唾液没有病毒这是正确的。

http://www.cdc.gov/hiv/resources/qa/transmission.htm，Scientists and medical authorities agree that HIV does not survive well outside the body, 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. 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 for days or even weeks under precisely controlled and limited laboratory conditions, CDC studies have shown that drying of even these high concentrations of HIV reduces the amount of infectious virus 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 interpretations of conclusions drawn from laboratory studies have in some instances caused unnecessary alarm.

不是失去感染性，是死亡。一旦离开宿主就失活。美国CDC官网原话。什么叫离开宿主？什么叫离开宿主？！Scientists and medical authorities agree that HIV does not survive well outside the body, 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. To obtain data on the survival of HIV, laboratory studies have required the use of artificially high concentrations of laboratory-grown virus.
