The human race is always struggling
against natures forces and attemptingto conquer over its ability to harm us
but so far such a victory has been
impossible. One of the most deadlydiseases to attack the human race inthe twentieth century is Acquired
immune deficiency syndrome (AIDS).

The first case was found in England in1959. A young British sailor developed an
illness that was never seen before. Hehad developed skin lesions and gingivitis,but soon he also developed high fever,
fatigue, shortness of breath and weightloss. Sir Robert Platt recorded hisconcerns in the patients chart. He feared
that the human race was now witnessingthe arrival of a new type of viral threat.

An autopsy was performed and tissue
samples were taken in hope that they
would later be able to understand theenigmatic sickness. The second case
occurred in St. Louis, Missouri 1968. A
fifteen year-old boy was admitted inthe hospital with widespread swelling
where he died a few months later. The
autopsy revealed a form of rare cancer.The doctor froze some tissue and fluid
samples.

In 1989 research began and the doctors
came to the conclusion that both men
had suffered from AIDS. The reportsuggested that AIDS dated back to the
beginning of the twentieth century. The
scientist traced the reports and theydated back to the 1902 when 7 caseswere recorded in Italy. This was followed
by twenty-two other cases throughoutEurope and the Americans. They were alladult males.

After reviewing this event it seems likely that
this virus has been among humanity for a very
long time. A very obvious question arise: whydid HIV explode at this certain time? The
precise reason is yet unknown but researchers
believe that the ease of international air
travel, the use of hypodermic needles, bloodtransfusion and the increased sexual freedomare some of the reasons. It is also believed that
the virus may have evolved into a more violentform through natural adaptive processescommon to such organism.

More cases were reported during the 1980where five young homosexual men had
developed Pneumocystis pneumonia. Onemonth later ten other cases were found,they were all homosexuals. The doctors
were starting to believe that the syndromewas restricted to those of this sexualorientation. This was an erroneousassumption. Many heterosexual men and
women believed that they were not at riskso they engaged in unsafe sex, there by theyexposed themselves to the virus

Society was very cruel and unsupportive
to those with AIDS. Pregnant women
could transmit the virus to the baby,and in this manner entire families could
be destroyed. In 1983, Dr. Luc
Montagnir and his colleaguesdiscovered the virus that produced
AIDS. A second breakthrough occurred
in 1985 where tests indirectly measuredthe presence of the virus in the
bloodstream.

In addition drugs have been
produced to slow the virussreproduction in a individuals body,
delaying the onset of symptoms for
months or years. Treatmentsenhancing the longevity and quality
of the life of HIV-infected peoplehave been created.

To date, nearly 180,000 Americans have beendiagnosed as having symptoms of AIDS, while
up to one million carry the virus without anyobvious symptoms. The Center for DiseaseControl predicts that 40.000 new HIV infections
will occur each coming year in adolescents andadults, along with 2.000 infections innewborns.Over 370,000 cases have been reported
worldwide. It is predicted that in the 1990s theadults infected with HIV will reach the fortymillions. In Western Europe the number of AIDScases is climbing.

The only thing we can do is hope that the
spread of the virus will ebb at some pointdue either to natural processes or to ourown scientific achievement. It is up to us,as responsible individuals to protect
ourselves and others from contracting thevirus. And if anyone has reason to believethat they might be carrying the virus, they
should consider undergoing a blood testto determine whether you are infected ornot.
