Aids Essay, Research Paper


AIDS is a life and death issue. To have the AIDS disease


is at present a sentence of slow but inevitable death. I’ve


already lost one friend to AIDS. I may soon lose others. My own


sexual behavior and that of many of my friends has been


profoundly altered by it. In my part of the country, one man in


10 may already be carrying the AIDS virus. While the figures may


currently be less in much of the rest of the country, this is


changing rapidly. There currently is neither a cure, nor even an


effective treatment, and no vaccine either. But there are things


that have been PROVEN immensely effective in slowing the spread


of this hideously lethal disease. In this essay I hope to


present this information. History and Overview:


AIDS stands for Acquired Immune Defficiency Disease. It is


caused by a virus.


The disease originated somewhere in Africa about 20 years


ago. There it first appeared as a mysterious ailment afflicting


primarily heterosexuals of both sexes. It probably was spread


especially fast by primarily female prostitutes there. AIDS has


already become a crisis of STAGGERING proportions in parts of


Africa. In Zaire, it is estimated that over twenty percent of


the adults currently carry the virus. That figure is increasing.


And what occurred there will, if no cure is found, most likely


occur here among heterosexual folks.


AIDS was first seen as a disease of gay males in this


country. This was a result of the fact that gay males in this


culture in the days before AIDS had an average of 200 to 400 new


sexual contacts per year. This figure was much higher than


common practice among heterosexual (straight) men or women. In


addition, it turned out that rectal sex was a particularly


effective way to transmit the disease, and rectal sex is a


common practice among gay males. For these reasons, the disease


spread in the gay male population of this country immensely more


quickly than in other populations. It became to be thought of as


a “gay disease”. Because the disease is spread primarily by


exposure of ones blood to infected blood or semen, I.V. drug


addicts who shared needles also soon were identified as an


affected group. As the AIDS epidemic began to affect


increasingly large fractions of those two populations (gay males


and IV drug abusers), many of the rest of this society looked on


smugly, for both populations tended to be despised by the


“mainstream” of society here.


But AIDS is also spread by heterosexual sex. In addition,


it is spread by blood transfusions. New born babies can acquire


the disease from infected mothers during pregnancy. Gradually


more and more “mainstream” folks got the disease. Most recently,


a member of congress died of the disease. Finally, even the


national news media began to join in the task of educating the


public to the notion that AIDS can affect everyone.


Basic medical research began to provide a few bits of


information, and some help. The virus causing the disease was


isolated and identified. The AIDS virus turned out to be a very


unusual sort of virus. Its genetic material was not DNA, but


RNA. When it infected human cells, it had its RNA direct the


synthesis of viral DNA. While RNA viruses are not that uncommon,


very few RNA viruses reproduce by setting up the flow of


information from RNA to DNA. Such reverse or “retro” flow of


information does not occur at all in any DNA virus or any other


living things. Hence, the virus was said to belong to the rare


group of virues called “Retro Viruses”. Research provided the


means to test donated blood for the presence of the antibodies


to the virus, astronomically reducing the chance of ones getting


AIDS from a blood transfusion. This was one of the first real


breakthroughs. The same discoveries that allowed us to make our


blood bank blood supply far safer also allowed us to be able to


tell (in most cases) whether one has been exposed to the AIDS


virus using a simple blood test.


The Types of AIDS Infection:


When the AIDS virus gets into a person’s body, the results


can be broken down into three general types of situations: AIDS


disease, ARC, and asymptomatic seropositive condition.


The AIDS disease is characterized by having one’s immune


system devastated by the AIDS virus. One is said to have the


*disease* if one contracts particular varieties (Pneumocystis,


for example) of pneumonia, or one of several particular


varieties of otherwise rare cancers (Kaposi’s Sarcoma, for


example). This *disease* is inevitably fatal. Death occurs often


after many weeks or months of expensive and painful hospital


care. Most folks with the disease can transmit it to others by


sexual contact or other exposure of an uninfected person’s blood


to the blood or semen of the infected person.


There is also a condition referred to as ARC (”Aids


Related Complex”). In this situation, one is infected with the


AIDS virus and one’s immune system is compromised, but not so


much so that one gets the (ultimately lethal) cancers or


pneumonias of the AIDS disease. One tends to be plagued by


frequent colds, enlarged lymph nodes, and the like. This


condition can go on for years. One is likely to be able to


infect others if one has ARC. Unfortunately, all those with ARC


are currently felt to eventually progress to getting the full


blown AIDS disease.


There are, however, many folks who have NO obvious signs


of disease what so ever, but when their blood serum is tested


they show positive evidence of having been exposed

to the virus.


This is on the basis of the fact that antibodies to the AIDS


virus are found in their blood. Such “asymptomatic but


seropositive” folks may or may not carry enough virus to be


infectious. Most sadly, though, current research and experience


with the disease would seem to indicate that EVENTUALLY nearly


all folks who are seropostive will develop the full blown AIDS


disease. There is one ray of hope here: It may in some cases


take up to 15 years or more between one’s becoming seropositive


for the AIDS virus and one’s developing the disease. Thus, all


those millions (soon to be tens and hundreds of millions) who


are now seropositive for AIDS are under a sentence of death, but


a sentence that may not be carried out for one or two decades in


a significan fraction of cases. Medical research holds the


possibility of commuting that sentence, or reversing it.


There is one other fact that needs to be mentioned here


because it is highly significant in determining recommendations


for safe sexual conduct which will be discussed below:


Currently, it is felt that after exposure to the virus, most


folks will turn seropositive for it (develop a positive blood


test for it) within four months. It is currently felt that if


you are sexually exposed to a person with AIDS and do not become


seropositive within six months after that exposure, you will


never become seropositive as a result of that exposure.


Just to confuse the issue a little, there are a few folks


whose blood shows NO antibodies to the virus, but from whom live


virus has been cultured. Thus, if one is seronegative, it is not


absolute proof one is not exposed to the virus. This category of


folks is very hard to test for, and currently felt to be quite


rare. Some even speculate that such folks may be rare examples


of those who are immune to the effects of the virus, but this


remains speculation. It is not known if such folks can also


transmit the virus.


Transmission of AIDS:


The AIDS virus is extremely fragile, and is killed by


exposure to mild detergents or to chlorox, among other things.


AIDS itself may be transmitted by actual virus particles, or by


the transmission of living human CELLS that contain AIDS viral


DNA already grafted onto the human DNA. Or both. Which of these


two mechanisms is the main one is not known as I write this


essay. But the fact remains that it is VERY hard to catch AIDS


unless one engages in certain specific activities.


What will NOT transmit AIDS?


Casual contact (shaking hands, hugging, sharing tools)


cannot transmit AIDS. Although live virus has been recovered


from saliva of AIDS patients, the techniques used to do this


involved concentrating the virus to extents many thousands of


times greater than occurs in normal human contact, such as


kissing (including “deep” or “French” kissing). Thus, there


remains no solid evidence that even “deep” kissing can transmit


AIDS. Similarly, there is no evidence that sharing food or


eating utensils with an AIDS patient can transmit the virus. The


same is true for transmission by sneezing or coughing. There just


is no current evidence that the disease can be transmitted that


way.The same may be true even for BITING,though here there may be


some increased (though still remote) chance of transmitting the


disease.


The above is very important. It means that there is NO


medical reason WHAT SO EVER to recommend that AIDS suffers or


AIDS antibody positive folks be quarrantined. Such


recommendations are motivated either by ignorance or by sinister


desires to set up concentration camps. Combined with the fact


that the disease is already well established in this country,


the above also means that there is no rational medical basis for


immigration laws preventing visits by AIDS suffers or antibody


positive persons.


The above also means that friends and family and coworkers


of AIDS patients and seropostive persons have nothing to fear


from such casual contact. There is no reason to not show your


love or concern for a friend with AIDS by embracing the person.


Indeed, there appears still to be NO rational basis for


excluding AIDS suffers from food preparation activity. Even if


an AIDS suffer cuts his or her finger and bleeds into the salad


or soup, most of the cells and virus will die, in most cases,


before the food is consumed. In addition, it is extremely


difficult to get successfully attacked by AIDS via stuff you


eat.


AIDS cannot be transmitted by the act of GIVING blood to a


blood bank. All equipment used for such blood donation is


sterile, and is used just once, and then discarded.


How is AIDS transmitted?


Sexual activity is one of the primary ways AIDS is


transmitted. AIDS is transmitted particulary by the transmission


of blood or semen of an infected person into contact with the


blood of an uninfected person. Sex involving penetration of the


penis into either the vagina of a woman or the rectum of either


a woman or a man has a very high risk of transmitting the


disease. It is felt to be about four times MORE likely for an


infected male to transmit AIDS to an uninfected woman in the


course of vaginal sex than it is likely for an infected woman to


transmit AIDS to an uninfected male. This probably relates to


the greater area of moist tissue in a woman’s vagina, and to the


relative liklihood of microscopic tears to occur in that tissue


during sex. But the bottom line is that AIDS can be transmitted


in EITHER direction in the case of heterosexual sex.
