4. HIV IS FOUND IN BODY
FLUIDS
Semen
Breast milk
Blood
Vaginal fluid

5. How HIV is passed on?
During unprotected (skin to skin) sex (anal,
vaginal or oral)
Contact with HIV infected blood or blood
products
Sharing IV drug needles of HIV positive people
From HIV positive mother to child
During breast feeding

6. Basics of HIV and AIDS
Cont…
Transmission of the virus occurs most
commonly through the exchange of body
fluids by:
1.Sexual contact with an infected person
2.Sharing infected needles, syringes or
other injection equipment with someone
who is infected.
3.Mother-to-child transmission
4.Transmission during blood transfusion
HIV enters the body through open cuts, sores, or breaks in the skin;
through mucous membranes, or through direct injection.

7. You CANNOT get HIV
from…
Tears
Saliva
Sweat
Urine
of an HIV infected person

8. Basics of HIV and AIDS
Cont…
HIV is NOT spread through:
•Casual / social contact
•Kissing and hugging
•Mosquito bites
•Using same utensils / towels, etc.
•Sharing the same wash-rooms
•By touching items that were touched by an
infected person

9. Window Period
When a person gets infected it may take 6
weeks or up to 3 months before antibodies
to HIV are detected in the blood
The HIV test looks for antibodies. When
these antibodies are detected the person is
diagnosed HIV positive
A person can be positive and the test shows
negative because the test was done during
the window period

10. Why HIV rates not going Why HIV rates not going
down?down?
Sex at an early age
Little life-skills and sex education
Little condom use
Multiple partners
Stigma and Discrimination
Sex for money or sex for .....things
Substance abuse: Ganja, cocaine, alcohol
Men having sex with men & homophobia
Gender inequity and gender roles

11. STI and HIV – The LinkSTI and HIV – The Link
Persons with a history of STIs are more likely to get
HIV because:

persons with STIs are more likely to have sores
and small breaks in the skin and lining of their
genitals.

HIV can more easily enter the body through
these breaks.
You can get an STI by having sex without a condom,
with an infected person.
At the same time, you could be getting HIV which is
also contracted by having unprotected sex.

12. ALL STIs are
Preventable
Most STI’s are treatable
But
HIV/AIDS CANNOT BE CURED

34. Prevention
Talk with partner about HIV
Use a condom with your regular and non-
regular clients, and partners every time
you have sex
Reduce the number of main partners
Get tested. Know your status

35. Who is most at risk for HIV?
Anybody having sex without a condom.
People with more than 1 partner who
don’t use a condom during sex
People whose sex partner have sex with
other partners without using a condom

36. How You DON’T Get HIV
You CANNOT get HIV by
hugging, touching,
living with or caring for
someone with HIV,
shaking hands or
kissing.
You CANNOT get HIV
from eating out of the
same plate or cup or
utensils that an HIV
positive person uses.

37. Early Signs & Symptoms of AIDSEarly Signs & Symptoms of AIDS
Fever
 Fatigue
 Night Sweats
 Loss of Appetite
 Diarrhea
 Swollen Lymph Glands
Remember these are symptoms of many other illnesses.

38. REMEMBER
You CANNOT tell by looking if someone has
HIV.
An individual can look and feel well for many
years and be HIV positive.
The HIV positive person can pass the virus on to
someone else.

39. The AIDS epidemic has taught us to be innovative and
to invent, test and implement new interventions. We
now have evidence of HIV prevention strategies that
work!

40. However, despite our innovation, inventiveness
and compelling evidence of effective
strategies, the “killer virus” is still chasing
and killing us!
