WORLD AIDS DAY

Presented by:M.Mohsin Anayat

PRESENTATION

World AIDS Day 2010WORLD AIDS DAY WORLD AIDS DAY, OBSERVED DECEMBER 1 EACH YEAR, IS DEDICATED TO RAISING AWARENESS OF THE AIDS PANDEMIC CAUSED BY THE SPREAD OF HIV INFECTION. IT IS COMMON TO HOLD MEMORIALS TO HONOR PERSONS WHO HAVE DIED FROM HIV/AIDS ON THIS DAY. GOVERNMENT AND HEALTH OFFICIALS ALSO OBSERVE THE EVENT, OFTEN WITH SPEECHES OR FORUMS ON THE AIDS TOPICS

Beginning of World Aids Day : Beginning of World Aids Day World AIDS Day was first conceived in August 1987 by James W. Bunn and Thomas Netter, two public information officers for the Global Programme on AIDS at the World Health Organization in Geneva, Switzerland Bunn and Netter took their idea to Dr. Jonathan Mann, Director of the Global Programme on AIDS (now known as UNAIDS). Dr. Mann liked the concept, approved it, and agreed with the recommendation that the first observance of World AIDS Day should be 1 December, 1988.

WHAT IS AIDS?

AIDS

Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV).

HISTORY OF AIDS: In 1981, the first cases of AIDS (Acquired Immune Deficiency Syndrome) were identified among gay men in the United States, acquiring the designation,GRID(Gay-Related By the end of 2003, twelve million children inSub-Saharan Africa were orphaned by AIDS.

DIFFERENCE BETWEEN AIDS AND HIV.

HIV causes AIDS by damaging the immune system cells until the immune system can no longer fight off other infections that it would usually be able to prevent.

RATIO OF GLOBALLY EFFECTED PEOPLE

In 2007, UNAIDS estimated: 33.2 million people worldwide had AIDS that year; AIDS killed an 2.1 million people in the course of that year, including 330,000 children, and 76% of those deaths occurred in sub-Saharan Africa. According to UNAIDS 2009 report, worldwide some 60 million people have been infected, with some 25 million deaths, and 14 million orphaned children in southern Africa alone since the epidemic began

CAUSES

AIDS is the ultimate clinical consequence of infection with HIV.

HIV is a retrovirus that primarily infects vital organs of the human immune system such as CD4+T cells (a subset of T cells), macrophages and dendritic cells. It directly and indirectly destroys CD4+ T cells.

WHO disease staging systemIn 1990, the World Health Organization (WHO) grouped these infections and conditions together by introducing a staging system for patients infected with HIV-1.[75] An update took place in September 2005. Most of these conditions are opportunistic infections that are easily treatable in healthy people.Stage I: HIV infection is asymptomatic and not categorized as AIDSStage II: includes minor mucocutaneous manifestations and recurrent upper respiratory tract infectionsStage III: includes unexplained chronic diarrhea for longer than a month, severe bacterial infections and pulmonary tuberculosisStage IV: includes toxoplasmosis of the brain, candidiasis of the esophagus, trachea, bronchi or lungs and Kaposi's sarcoma; these diseases are indicators of AIDS.

Ryan White became a poster child for HIV after being expelled from school because of his infection.

According to UNAIDS estimates, there are now 33.3 million people living with HIV, including 2.5 million children.

During 2009 some 2.6 million people became newly infected with the virus and an estimated 1.8 million people died from AIDS.

Global prevalence of AIDS An estimated 33.4 million people living with HIV globally and 2.7 million newly infected in 2008, countries continue to rank AIDS high on the list of the most important issues facing the world.

CURRENT RATIO:

Estimate Range

People living with HIV/AIDS in 2009

33.3 million 31.4-35.3 million

Adults living with HIV/AIDS in 2009

30.8 million 29.2-32.6 million

Women living with HIV/AIDS in 2009

15.9 million 14.8-17.2 million

Children living with HIV/AIDS in 2009

2.5 million 1.6-3.4 million

People newly infected with HIV in 2009

2.6 million 2.3-2.8 million

Adults newly infected with HIV in 2009

2.2 million 2.0-2.4 million

AIDS deaths in 2009 1.8 million 1.6-2.1 million

Orphans (0-17) due to AIDS in 2009

16.6 million 14.4-18.8 million

Global HIV and AIDS estimates, end of 2009The latest statistics of the global HIV and AIDS epidemic were published by UNAIDS in November 2010, and refer to the end of 2009.At the end of 2009, women accounted for just over half of all adults living with HIV worldwide.

Global trends

The number of people living with HIV rose from around 8 million in 1990 to 33 million by the end of 2009. The overall growth of the epidemic has stabilised in recent years. The annual number of new HIV infections has steadily declined and due to the significant increase in people receiving antiretroviral therapy, the number of AIDS-related deaths has also declined.

AIDS IN ASIA

Today, around 4.87 million people are living with HIV in South, East and South-east Asia.1 Although national HIV prevalence rates in Asia appear to be relatively low, the populations of some Asian countries are so vast that these low percentages actually represent very large numbers of people living with HIV. In India, for example, an estimated 0.1% of adults aged 15-49 are living with HIV, which seems low when compared to prevalence rates in some parts of sub-Saharan Africa. However, with a population of around one billion, this actually equates to 2.3 million adults living with HIV in India.{!ref: UNAIDS (2010)

AIDS IN PAKISTAN

HIV is not currently a dominant epidemic in Pakistan

The National AIDS Programme’s latest figures show that over 4,000 HIV cases have so far been reported since 1986, but UN and government estimates put the number of HIV/AIDS cases around 97,000 ranging from lowest estimate 46,000 to highest estimate-210,000. More realistic estimates that are based on actual surveillance figures, however, suggest that this number may be closer to 40,000 - 45,000. The over all prevalence of HIV infection in adults aged 15 to 49 is 0.1% (0.05% if one accepts the lower estimates). Officials say that the majority of cases go unreported due to social taboos about sex and victims’ fears of discrimination

PREVENTON AND TREATMENT:

Antiretroviral drugs keep the levels of HIV in the body at a low level, so that the immune system is able to recover and work effectively. Antiretroviral drugs enable many HIV positive people to live long and healthy lives.
