Hi guys, today I want to tell you
all about the popular HIV virus. I say
popular because almost every average Nigerian have heard about it, but yet the
HIV is being taken for granted by most of us.
HIV
is an acronym which stands for HUMAN IMMUNODEFICIENCY VIRUS. It is a
lenti virus that causes the Acquire Immunodeficiency Syndrome (AIDS), a condition in humans in which progressive failure of the immune system allows life threatening opportunistic functions and cancer to thrive.

AIDS
(Acquired Immune deficiency Syndrome or Immunodeficiency Syndrome is a disease
caused by a virus called HIV. The illness alters the immune system, making
people much more vulnerable to infections and diseases. A man’s susceptibility
worsens as the disease progresses with time.
The
origin of HIV dates back to the late 19th or early 20th
century in west central Africa.
AIDS
and its causes, HIV were first identified and recognized in the early 1980s. By
1985 the causative agent (HIV) was been identified, and was determined to be an
advanced stage of chronic HIV infection.
HIV
is a devastating global pandemic. Statistics show that the mortality rate is
about 25 million people world wide, PLWH (People Living With HIV) is over 33
million people, estimated 2.7 million people are newly infected yearly with HIV
and 2 million people die of HIV related causes.
HIV
is a fragile virus which can only be transmitted under specific conditions that
allows contact with infected blood, semen, vaginal secretions and breast milk.
Transmission
of HIV occurs through sexual intercourse with an infected partner, exposure to
HIV infected blood or blood products, infected needles. Peri-natal transmission
occurs during pregnancy, at delivery, or through breastfeeding.
Sexual transmission is the most
common route. During sexual intercourse (anal, vaginal or oral) the risk of
infection is greater for the partner who receives the semen because the
receiver has prolonged contact with the infected fluids. This explains why it
is easier to infect women than men during heterosexual intercourse.
Transmission rates are shown
below;
-
Per sex act
with infected person; male to female is 0.1 to 0.2%
-
By blood
transfusion is 90%
-
By injection
of drugs 0.7 to 0.8%
-
Breast
feeding is 10 to 15%
In all, women are more vulnerable
to heterosexual transmission because of their large mucosal exposure to semen,
biology of the HIV virus, poverty (low socio-economic status which is as a
result of:
-
High
prevalence of non-consensual sex
-
Sex without
condom use
-
Unknown or
high risk behavior of partners
-
Young women
with much older partners
