Antiretroviral treatment can prolong the time between HIV infection and the onset of AIDS. Modern combination therapy is highly effective and someone with HIV who is taking treatment could live for the rest of their life without developing AIDS.

An AIDS diagnosis does not necessarily equate to a death sentence. Many people can still benefit from starting antiretroviral therapy even once they have developed an AIDS defining illness. Better treatment and prevention for opportunistic infections have also helped to improve the quality and length of life for those diagnosed with AIDS.

Treating some opportunistic infections is easier than others. Infections such as herpes zoster and candidiasis of the mouth, throat or vagina, can be managed effectively in most environments. On the other hand, more complex infections such as toxoplasmosis, need advanced medical equipment and infrastructure, which are lacking in many resource-poor areas.

It is also important that treatment is provided for AIDS related pain, which is experienced by almost all people in the very advanced stages of HIV infection.

Why do people still develop AIDS today?

Even though antiretroviral treatment can prevent the onset of AIDS in a person living with HIV, many people are still diagnosed with AIDS today. There are four main reasons for this:

• In many resource-poor countries antiretroviral treatment is not widely available. Even in wealthier countries, such as America, many individuals are not covered by health insurance and cannot afford treatment.
• Some people who became infected with HIV in the early years of the epidemic before combination therapy was available, have subsequently developed drug resistance and therefore have limited treatment options.
• Many people are never tested for HIV and only become aware they are infected with the virus once they have developed an AIDS related illness. These people are at a higher risk of mortality, as they tend to respond less well to treatment at this stage.
• Sometimes people taking treatment are unable to adhere to, or tolerate the side effects of drugs.
