Some basic fact about HIV:

HIV continues to be a major global public health
issue, having claimed more than 36 million lives so
far.
There were approximately 35.3 [32.2–38.8] million
people living with HIV in 2012.
Sub-Saharan Africa is the most affected region, with
nearly 1 in every 20 adults living with HIV. Sixty nine
per cent of all people living with HIV are living in this
region.
HIV infection is usually diagnosed through blood
tests detecting the presence or absence of HIV
antibodies.
There is no cure for HIV infection. However, effective
treatment with antiretroviral drugs can control the
virus so that people with HIV can enjoy healthy and
productive lives.
In 2012, more than 9.7 million people living with HIV
were receiving antiretroviral therapy (ART) in low-
and middle-income countries.

Transmission
HIV can be transmitted via the exchange of a variety
of body fluids from infected individuals, such as
blood, breast milk, semen and vaginal secretions.
Individuals cannot become infected through ordinary
day-to-day contact such as kissing, hugging, shaking
hands, or sharing personal objects, food or water.
Risk factors
Behaviours and conditions that put individuals at
greater risk of contracting HIV include:
having unprotected anal or vaginal sex;
having another sexually transmitted infection such
as syphilis, herpes, chlamydia, gonorrhoea, and
bacterial vaginosis;
sharing contaminated needles, syringes and other
injecting equipment and drug solutions when
injecting drugs;
receiving unsafe injections, blood transfusions,
medical procedures that involve unsterile cutting or
piercing; and
experiencing accidental needle stick injuries,
including among health workers.
