HIV/AIDS is a global pandemic. As of 2014, approximately 37 million
people have HIV worldwide with the number of new infections that year being
about 2 million. This is down from 3.1 million new infections in 2001. Of
these 37 million more than half are women and 2.6 million are less than
15 years old. It resulted in about 1.2 million deaths in 2014, down from
a peak of 2.2 million in 2005 (Cohen & Hellmann, 2015).

Sub-Saharan Africa is the region most affected. In 2010, an estimated
68% (22.9 million) of all HIV cases and 66% of all deaths
(1.2 million) occurred in this region. This means that about 5% of the adult
population is infected and it is believed to be the cause of 10% of all deaths
in children. Here in contrast to other regions women compose nearly 60% of
cases. South
Africa has the largest population
of people with HIV of any country in the world at 5.9 million. Life
expectancy has fallen in the
worst-affected countries due to HIV/AIDS; for example, in 2006 it was estimated
that it had dropped from 65 to 35 years in Botswana. Mother-to-child
transmission, as of 2013, in Botswana and South Africa has decreased to less
than 5% with improvement in many other African nations due to improved access
to antiretroviral therapy (Mandell, 2014).

Although
HIV prevalence is much lower in Nigeria (estimated 3.4% of the populations are
living with HIV) than in many African countries, such as South Africa, Uganda,
and Zambia, the size of Nigeria’s population means that in no distance future
the number of people leaving with HIV will almost double. Approximately 210,000
people die yearly and the natural life expectancy is 56 years (Odutolu, 2006).
