HIV (Human Immunodeficiency Virus) is the virus that
causes AIDS. This virus attacks the body's immune system, lowering its
ability to fight disease.
How can a person become infected by the virus?
HIV is present in blood, semen, vaginal fluids and breast milk. Through
one of these body fluids, the virus must enter a break in the skin or be
absorbed through mucous membranes (e.g. eyes, mouth) of another person
to pass on the infection. HIV cannot be passed through casual contact
such as hugging or kissing.
HIV is spread by:
- sharing drug equipment, needles and/or syringes
- anal sex (penis in rectum)
- vaginal sex (penis in vagina)
- oral sex:
- if semen enters the mouth
- if menstrual blood/vaginal fluids contact the mouth
- sores present on the mouth or genitals may increase the risk of
transmission
- sharing sex toys
- an infected mother to her unborn or breastfed baby
- unsterile equipment for tattooing, electrolysis, ear/body piercing,
acupuncture
- receiving donated organs and semen before July 1987 when screening began
in Canada
- receiving blood or blood products before November 1985 when screening
began in Canada
HIV cannot be spread by:
- casual, every day contact
- shaking hands
- hugging, kissing
- coughing, sneezing
- giving blood
- using swimming pools, toilet seats
- sharing bed linen, eating utensils or food
- mosquitos or other insects, animals
It is important to avoid exposure to another sexually transmitted
infection (STI). Having an STI can weaken your body's natural protection
and increase your chances of becoming infected with HIV if you are
exposed to the virus.
Testing
A blood test is done to find antibodies to HIV. Testing is not advised
until 3 months after the last possible exposure to the virus, as it can
take that long for antibodies to develop in the body. This time is
called the window period.
All HIV testing is confidential. It can also be done anonymously at Peel
Health department clinics. Only clinic staff has access to these files.
Your date of birth and identification number is used on the lab slip.
Blood is sent to the Ministry of Health lab for testing.
Test Results
The results of the test will be given in person only and not over the
phone.
A negative test means you do not have the antibodies now. If it has been
less than 3 months you should consider retesting. If it has been 3
months after your last exposure and your test is negative, you do not
have HIV. If you engage in high risk activities, you may become infected
with the virus at any time. It is important to talk to your partner(s)
to determine their HIV test status and if it was outside the 3 month
window period.
A positive test means that you have antibodies for HIV. You do not AIDS.
No one knows when someone infected with the virus will develop AIDS. An
early diagnosis allows you to get medical advice and early treatment.
People who are HIV positive can pass the virus to others. Your sexual
partners must be told of your infection so that they can be tested. You
may want to share this information with anyone else who is exposed to
your body fluids, such as doctors and dentists.
Precautions:
- Regardless of test results, precautions should be taken to reduce the
risk of getting HIV.
Precautions include:
- using lubricated condoms for vaginal sex
- using non-lubricated condoms for oral sex on a man
- using a latex barrier (called a dam) or a condom cut length-wise for
oral sex on a woman
- using condoms with extra lubricant for anal sex
- limiting the number of sex partners
- not sharing needles, syringes, drug equipment or sex toys
