How is HIV transmitted?

How is HIV transmitted?

HIV infection most commonly occurs through sexual contact. However, the virus can also be spread through blood-to-blood contact -- such as sharing needles or blood transfusions involving unscreened blood. Studies have shown that HIV is not transmitted through casual contact such as touching or sharing towels, bedding, utensils, telephones, swimming pools, or toilet seats. Scientists have also found no evidence of transmission through kissing, sweat, tears, urine or feces. It is important to acknowledge that it is not sex that transmits HIV, but certain bodily fluids: blood, semen (including "pre-cum"), vaginal secretions and breast milk. High-risk behaviors that can result in HIV transmission are sharing needles for drugs, tattoos, body piercing, vitamins or steroids with an HIV-infected person and/or engaging in unprotected anal, vaginal or oral sex with a person who is HIV infected. The virus also can be transmitted from an HIV-infected mother to her child through pregnancy, birth or breastfeeding.

It does appear that persons already infected with a sexually transmitted disease are more susceptible to acquiring HIV during sex with an infected partner. Mucous membranes, a weak point in the skin, include the lips, mouth, vagina, vulva, penis or rectum. Because mucous membranes are porous and viruses and other pathogens are able to pass through, these areas are rich in immune cells. When a person already has a sexually transmitted disease, sex organs may be flooded with CD4+T cells, making it much easier for HIV to infect.

The only way to determine HIV infection is to be tested for the virus. It is not unusual for HIV-infected persons to experience symptoms years after the initial infection; some may be symptom free for over 10 years. However, during the asymptomatic period, the virus is actively multiplying and destroying cells in the immune system, weakening the body's ability to fight infection. The effect is most keenly observed in the decline of the immune system's key infection fighters in the blood, the CD4+T cells. There are medical treatments that can reduce the rate at which HIV disables the immune system; early detection offers more options for treatment and preventative care. As a matter of safety, people who engage in high-risk behaviors -- such as intravenous drug use or having unprotected sex with multiple partners -- should be tested regularly.

IMPORTANT

HIV is a fragile virus that does not survive very long outside the body.

You cannot contract HIV from:

 

• Air conditioning

• Sitting next to or touching someone who is HIV positive

• Toilet seats

• Giving blood at the blood bank
• Money.

 

No evidence has been found to suggest that anyone has contracted HIV through:

 

• Sweat, saliva or tears

• Coughing, sneezing or spitting

• Swimming pools

• Drinking bubblers

• Mosquitoes or other biting insects.

After infection, many people can remain well with no symptoms for many years. However, even if someone infected with HIV has no symptoms, they can still spread the disease.Infection with HIV does not mean a person has AIDS. A diagnosis of AIDS is made only when the immunme system breaks down, leading to infections and cancers. Diagnosis may require a number of special tests to be performed.

 

HIV tests

Detecting HIV

 

People who become infected with HIV develop antibodies (proteins the body makes to fight germs) to the virus. It can take up to three months after infection with HIV before these antibodies can be detected.

 

The HIV antibody test is a simple blood test which shows if a person has been infected with the virus. The test does not tell if a person has AIDS or will go on to develop AIDS. Test results are usually available within 14 days.

 

If the test detects antibodies, the person is said to be HIV-positive (sometimes the term 'antibody-positive' is used).

 

It is important that pre- and post-test counselling are provided when having the test.

 

Monitoring HIV

The HIV RNA viral load test measures the amount of virus in people infected with HIV. This test is used to decide when to start treatment. It also helps to monitor the response to anti-retroviral medicines.

 

Treatments

The earlier a person is found to be HIV- positive, the earlier treatment can be started. Treatments for HIV improve quality of life and delay serious illness.

 

Treatments for HIV/ AIDS include medicines to:


• Reduce the amount of virus in the body (anti-rctrovirals)

• Prevent the serious illnesses of AIDS (prophylactic or preventative drugs)
• Treat infections and diseases that occur as part of AIDS.

 

Several anti-retroviral medicines am now available. They slow down HIV and may delay the onset of AIDS. Using different'
combinations of these medicines reduces the chances of the virus becoming resistant to treatment. However, the medicines need to be taken regularly and frequently as missed doses can give the virus a chance to grow.Taking drug treatments for HIV/AIDS can be very complicated and have a substantial impact on lifestyle and relationships.

 

Safe sex

When having sex (vaginal or anal), ahvays use a condom with a water-based lubricant.

 

Other forms of safe sex include:

• Kissing, including wet kissing (providing there are no cuts or sores in the areas, or bleeding gums)

• Oral sex (avoid semen in the mouth and/or use a condom or dental dam)

• Rimming and fisting (with glove or barrier)
• Mutual masturbation
• Massage

• Using dildos or vibrators (but never share them without cleaning them first).

 

Talk to your sexual partner about protecting yourselves and only have safe sex.

 

Self care

• Protect yourself against infection.

• Only have safe sex. Always use a condom.
• If you inject drugs, do not share injecting equipment and dispose of it safely.

• If you are at high risk of getting HIV, consider having an HIV test.

• Do not share razors, toothbrushes, etc.

• If you get any body piercing or tattoos, make sure the provider uses sterile equipment.

• If vou are at risk of HIV do not donate blood, organs or sperm.

• If you travel, be aware that most countries have a much higher incidence of HIV than Australia. Talk to your doctor and pharmacist if you
have any questions about treatments for HIV.
