艾滋病性传播几率?

艾滋病性传播几率?
　　“艾滋病有3种传播途径”现在成了小学生都知道的常识，可说到3种途径的艾滋病性传播几率有多少，即：血液传播、性传播、母婴传播。如果一个正常人输进了HIV（艾滋病病毒）阳性感染者或艾滋病病人的血液其感染的几率是95%，而一个HIV阳性感染者或已经发病的病人与一个正常人发生性关系的感染几率和性别有一定关系，男传给女的几率是0．2%，女传给男的几率是0．1%，男传男的几率要比以上两种方式大得多。如果母亲是一个HIV阳性或艾滋病的病人，其感染给胎儿的几率是25%，但是如果母亲经过AZT的抗病毒治疗，其胎儿的感染几率下降到8%；经过联合疗法（鸡尾酒疗法）治疗胎儿的感染几率可能下降为2%。

　　艾滋病病毒是一种十分脆弱的病毒，它对热和干燥十分敏感。在干燥的环境中，艾滋病毒10分钟死亡，在摄氏60度的环境中30分钟灭活。如果一支刚接触病人身体带有血液的注射器，马上刺入正常人体内，艾滋病性传播几率小于0．3%。地坛医院艾滋病房曾发生过几次在治疗、抢救艾滋病病人的过程中器械损伤医护人员的事情，其中一次是护士在给艾滋病病人注射后，针头掉下刚好扎在护士脚背上。经过一个月、三个月的艾滋病病毒抗体（HIV）跟踪检测，这些医护人员均未被艾滋病病毒感染。实验证明：艾滋病病毒生命力很弱，只能存活于血液中，离开适宜的条件立即死亡。离体病毒，在凝固的血液中不能长期存活。蚊虫叮咬不会传染艾滋病就是因为这个原因。

Chances of sexual transmission of AIDS?
"There are three kinds of transmission of AIDS," now the students know that common sense, can be said three kinds of ways of how many chances of sexual transmission of AIDS, namely: blood transmission, sexual transmission, mother to child transmission. If a normal input into the HIV (AIDS virus)-positive or AIDS patients infected with the blood of their risk of infection was 95%, while an HIV-positive or have been infected with the disease of patients with a normal sexual relationship between infection probability and have a certain gender relations, men and woman more likely to pass on 0.2% of men and women more likely to pass on 0.1%, male transmission risk of men is much greater than the above two methods. If the mother is an HIV-positive or AIDS patients, their risk of infection to the fetus is 25%, but if the mother's anti-virus after AZT treatment, the risk of fetal infection dropped to 8%; after combination therapy (HAART) in the treatment of fetal infection rates may be reduced to 2%.

AIDS virus is a very fragile virus, its very sensitive to heat and drying. In the dry environment, the HIV virus for 10 minutes dead, in an environment of 60 degrees Celsius for 30 minutes inactivated. If a newcomer to a patient's body with a syringe of blood and immediately penetrate normal human body, the AIDS risk of sexual transmission is less than 0.3%. Ditan Hospital AIDS rooms have occurred several times in the treatment of AIDS patients in the process of rescue equipment damage health care personnel matters, including a nurse to AIDS patients after injection, the needle fell just rolling on the instep of nurses. After a month, three months of HIV antibody (HIV) tracking and detection, none of these health care workers were infected with HIV. Results show: HIV vitality is weak and can only survive in the blood, leaving optimal conditions and died instantly. In vitro virus, in the coagulation of blood can not be long-term survival. Transmission of HIV from mosquito bites will not be because of this.
