This is a terrible disease, for which we do not yet have a cure. Nor do we have a vaccine. Meanwhile, the mortality rate for AIDS is 100 percent.
AIDS means that the immune system of a person has gone wrong. The immune system is the biological system in your body which fights off diseases. This system is composed mostly of what are commonly termed "white blood cells."
These cells are the hunters in the body. When a virus, such as the common cold, invades the body, the white blood cells rush to the invader and kill it.
While these blood cells are busy killing an invader, the body’s immune system is said to "be under attack." If another virus or bacteria enters the body at the same time as the white blood cells are busy fighting off an invader, the second attacker has a better chance of injuring the rest of the body’s system.
Scientists found the virus that causes AIDS and named it HIV. The HIV virus attacks the white blood cells and kills them, thus preventing these white cells from carrying on their important work of killing the other invading viruses.
We cannot tell if a person has an HIV infection just by looking at him. And here lies part of the problem about the spread of HIV infection among people. For at least the first few years after a person has contracted the HIV virus, there are no indications that the person has the HIV virus in his/her bloodstream.
However, during this time the person carrying the virus can pass it onto other people through intimate sexual relations or sharing blood with them.
Then how do we know if we have HIV or not? The answer is simple. Have an HIV blood test. This simple, painless AIDS test will take only a few minutes of your time, and, if you are at all in doubt about whether you might have contracted the HIV virus, it is a life-saving endeavor.
选项
答案
这是一种可怕的疾病。对于这种病我们至今还没找到治疗方法,也没有预防的疫苗。与此同时,目前艾滋病的死亡率几乎为100%。 得了艾滋病意味着一个人的免疫系统出了毛病。免疫系统是人体内与疾病抗争的生物系统。这一系统主要是由我们通常所称的“白血球”构成的。 这些白血球是体内的猎人。如果一种病毒,如普通感冒病毒,侵入人体内,白血球就会奋起迎击,杀死他们。 当白血球忙于与这些入侵者作战时,体内的免疫系统便处于“受到攻击”状态。这时,如果另一种病毒或细菌也侵入体内,这第二位入侵者会更容易使身体的其他系统受到损害。 科学家已发现了引起艾滋病的病毒,叫做HIV。这种病毒攻击并杀死白血球,使他们无法执行抵御入侵病毒的重要使命。 仅仅凭肉眼观察,我们并不能分辨出一个人是否感染上了HIV。这也就是HIV能在两个人或更多的人中得以传播的部分原因。因为一个健康的人感染上HIV病毒以后,至少在最初的几年里没有任何迹象表明他/她的血液里有HIV病毒。 然而在这一时期,这个带有病毒的人却能通过性行为或输血把病毒传染给他人。 那么,我们怎样才能知道自己是否受到了HIV的感染呢?答案很简单:去做一个HIV血液检验。这种简单的检验只需花你几分钟的时间。如果你对自己是否感染了HIV病毒心存疑虑,去做一个血液检查乃是救生之举。
