(human immunodeficiency virus) is a virus that attacks a cell in your body
called CD4 T cell, which is an important part of the body immune system that
protects the body and fights against the infections. And as our bodies can’t
get rid of this virus, once you get it it’ll stay there for the rest of your
life, and can eventually lead to the last stage of the HIV infection that’s
known as AIDS (acquired immunodeficiency syndrome).
today, there is no effective drug or treatment for the HIV virus. The main idea
of all the HIV treatments is to prolong the patient’s life and control the
symptoms but it is unable to get rid of the virus completely.
as we can see HIV is a serious disease that can ruin people lives and so we
should be too aware of it and try to prevent its transmission as much as
does the HIV transmit?
first step to prevent HIV infections is by knowing the ways of this virus
transmission. HIV can be transmitted generally by three ways: sexual contact,
from a mother to the fetus during pregnancy, and through blood. This includes
sharing needles to inject drugs and any other sharp objects that may expose you
to the HIV infected person’s blood, and of course blood transfusion. Thus, we
make sure in the blood bank to exclude the HIV infected people and who are at
risk of getting HIV from donating by a process called donor selection.
is donor selection?
is a process to determine whether the individual is suitable to donate blood or
not depending on the donation criteria and conditions, those include the age,
weight, general health, medical history and the present of any diseases,
especially the diseases that can be transmitted through the blood. One of those
is the HIV. Donor selection process starts with several questions including
questions about HIV to exclude any donors with HIV permanently or at high risk
of HIV temporarily. Those include if the person has AIDS symptoms, sex partner
with AIDS, homosexual or bisexual people, having multiple sex partners, drugs
abuse now or in the past, visiting of other countries with a high percentage of
HIV infected people.
is the purpose of blood donor selection?
main goal of any blood bank is to provide safe blood products. The first step
for that is the donor selection. By performing those procedures, we can protect
both the donor and the recipient by only taking blood from healthy donors and
providing safe blood eventually for the patient. In addition, The WHO Global
Database on Blood Safety indicates that every year in 164 countries there are
more than 92 million blood donations. However, from those units, there are 1.6
million units discarded due to infectious diseases including HIV. So by good
donor selection, we can avoid or reduce wasting this much of resources,
consumables, for tests, donor’s blood, and both donor and stuff time that
result from collecting unsuitable donations.
