 Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS or Aids) is a set of symptoms and infections resulting from the damage to the human immune system caused by the human immunodeficiency virus (HIV). This condition progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumors. HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. This transmission can involve anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, or breastfeeding, or other exposure to one of the above bodily fluids.
Although treatments for AIDS and HIV can slow the course of the
disease, there is currently no vaccine or cure. Antiretroviral
treatment reduces both the mortality and the morbidity of HIV
infection, but these drugs are expensive and routine access to
antiretroviral medication is not available in all countries. Due to
the difficulty in treating HIV infection, preventing infection is a key
aim in controlling the AIDS epidemic, with health organizations
promoting safe sex and needle-exchange programmes in attempts to slow
the spread of the virus.
Vast numbers of children across the world become infected with HIV
every year. Without treatment, thousands die as a result of AIDS. In
addition, millions more children who are not infected with HIV are
indirectly affected by the epidemic, as a result of the death and
suffering that AIDS causes in their families and their communities.
World AIDS Day was originally organised by UNAIDS, who chose the theme
after consultation with other organisations. In 2005 UNAIDS handed over
responsibility for World AIDS Day to an independent organisation known
as The World AIDS Campaign (WAC).
The WAC’s slogan for their work is "Stop AIDS: Keep the Promise". This
is an appeal to governments, policy makers and regional health
authorities to ensure that they meet the many targets that have been
set in the fight against HIV and AIDS, and especially the promise of
universal access to HIV treatment, care, support and prevention
services by 2010. This campaign will run until 2010, with a related
theme chosen for World AIDS Day each year.
The theme for 2007 and 2008 is “leadership”, highlighting the need for
innovation, vision and perseverance in the face of the AIDS challenge.
The campaign calls on all sectors of society such as families,
communities and civil society organisations - rather than just
governments - to take the initiative and provide leadership on AIDS.
