December 1 marks the World AIDS day 2009. It is an opportunity to reflect on the millions of people who have been victims of this disease and the millions more who are being infected each and every day, across the planet.
What is HIV?
HIV is a virus that attacks the body’s immune system – the body’s defence against diseases.
Are HIV and AIDS the same?
No. When someone is described as living with HIV, they have the HIV virus in their body. A person is considered to have developed AIDS when the immune system is so weak it can no longer fight off a range of diseases with which it would normally cope.
How is HIV passed on?
HIV can be passed on through infected blood, semen, vaginal fluids or breast milk.
The most common ways HIV is passed on are:
* Sex without a condom with someone living with HIV
* Sharing infected needles, syringes or other injecting drug equipment
* From an HIV-positive mother (to her child) during pregnancy, childbirth or breastfeeding (but with effective treatment and care the risk of transmission can be greatly reduced)
No, but treatment can keep the virus under control and the immune system healthy. People on HIV treatment can live a healthy, active life, although they may experience side effects from the treatment. If HIV is diagnosed late, treatment may be less effective.
