The World Health Organization says as many as 10 million persons worldwide may have the virus(病毒) that causes AIDS.Experts believe about 350 thousand persons have the disease.And one million more may get it in the next five years.In the United States,about 50,000 persons have died with AIDS.The countrys top medical official says more than 90 percent of all Americans who had the AIDS virus five years ago are dead.?
There is no cure for AIDS and no vaccine(疫苗) medicine to prevent it.However,researchers know much more about AIDS than they did just a few years ago.We now know that AIDS is caused by a virus.The virus invades healthy cells including white blood cells that are part of our defense system against disease.It takes control of the healthy cells genetic(遗传的) material and forces the cell to make a copy of the virus. The cell thendies.And the viral particles move on to invade and kill more healthy cells.The AIDS virus is carried in a persons body fluids.The virus can be passed sexually or by sharing instruments used to take intravenous(静脉内的) drugs.It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby.?
Many stories about the spread of AIDS are false.You cannot get AIDS by working or attending school with someone who has the disease.You can not get it by touching,drinking glasses or other objects used by such persons.Experts say no one has gotten AIDS by living with,caring for or touching an AIDS patient.?
There are several warning signs of an AIDS infection.They include always feeling tired,unexplained weight loss and uncontrolled expulsion of body wastes(大小便失禁). Other warnings are the appearance of white areas on the mouth ,dark red areas of skin that do not disappear and a higher than normal body temperature.
World AIDS Day is observed every year on December 1st.
Do you know AIDS？ AIDS is a terrible disease. Right now, it is a deadly disease and so far, it cannot be cured.There is no pill, no vaccine, no surgery to make you better. HIV and AIDS has decimated the world we live in, and things are only going to get worse.So it is called super killer.
At last estimate by UNAIDS, 40 million people have been infected with AIDS around the world.Every minute, five people get infected with AIDS! It is terrible, isnt?
Do you know about this red ribbon?It is called the AIDS Ribbon.On this day people wear red ribbons to show their support and to raise awareness. This started as a grassroots effort and there is still not one main manufacturer for the ribbons. The Red Ribbon united people to fight against AIDS.
You wont get AIDS if you:
work, eat and drink together with AIDS patients;
shake hands with them or hug them;
talk face to face with them;
use the same toilet as them;
swim with them.

艾滋病，已成了全世界人民共同关心的一个话题。怎样预防艾滋病，也就成了大家更为关注的话题。大家都知道艾滋病的可怕，都称它为魔鬼。那么，艾滋病到底是怎样的一个魔鬼？
通俗的讲，艾滋病是人体免疫系统被一种叫做HIV的病毒所破坏，因此身体丧失了抵抗力，不能与那些对生命威胁的病菌战斗，从而使人体发生多种不可治愈的感染和肿瘤，最后导致被感染者死亡的一种严重传染病。
据了解现全球约有3950万人感染艾滋病，每年都会增加430万人，也就是说世界上每隔8秒钟就会有11万人被感染艾滋病，而全球每天都有8000名感染者丧命。这是多么惊人的数字。
那么，艾滋病是怎样传染的呢？是血液、不洁性交、吸毒或静脉注射和母婴传播而引起的。有人问艾滋病是不是很严重？这是当然的，因为艾滋病毒引起的传染病，是一种死亡率极高的病，它的死亡率在所有的病中排名第2，艾滋病就像一股突如其来的风，唰一下子在你完全不知道的情况下降临并迅速蔓延。
在我国，艾滋病的流行情况又是怎样呢？从1985年开始，每年只有几例感染者，多数是国外来华的人士，或者是我们出国的人士。这样大概持续了四、五年。到了上世纪八十年代末，出现了第一个流行期：在云南边境，中国开始了艾滋病的流行。从九十年代中期开始，出现了快速增长期，其特点就是以很快的速度波及全国。从1994年到现在，将近10年的时间，一直都是在以40%以上的速度增长。
哪些是艾滋病的易感染者呢？人们经过分析，已清楚地发现了哪些人易患艾滋病，并把易患艾滋病的这些人统称为艾滋病易感染高危人群。艾滋病的易感染人群主要是指男性同性恋患者、静脉吸毒成瘾者、血友病患者，接受输血及其它血制品者、与以上高危人群有性关系的人等。
艾滋病威胁着每一个家庭，每一个人，因此预防艾滋病是全社会的责任。为了每一个家庭，每一个人的健康、幸福，我们应该怎么去预防艾滋病呢？
1、普及艾滋病知识，使人们了解它的病因、传播途径等。
2、避免不洁性交，尤其是避免与艾滋病人发生性接触。
3、对供血者进行艾滋病病毒检查，抗体阳性者禁止供血。
4、不共享针头和注射器及牙刷等可被血液污染的物品。
5、患艾滋病感染者的妇女禁止妊娠。
6、加强国境检疫，防止艾滋病的传入。
快加入到预防艾滋病的队伍中来吧！为了让世界永远充满微笑，为了家庭不再受沉重打击行动起来，严防艾滋病！让世界不再为之哭泣，让艾滋病永远消失。
