2001

Drug companies begin offering AIDS drugs to poor countries at a discount

An estimated $6.9 billion is spent in the U.S. on the treatment of AIDS patients

The UN estimates that, around the world during 2001, there were 3 million deaths from AIDS, of which 2.3 million were in Sub-Saharan Africa. There were 5 million new infections, bringing the total to 40 million infected; and Africa has the most infected (more than 16 million) followed by South and Southeast Asia (more than 6 million).

AIDS is spreading most rapidly in Eastern Europe and the Russian Federation, with 250,000 new infections in 2001

AIDS has lowered the life expectancy in Botswana, Malawi, Mozambique, and Swaziland by 20 years, to under 40 years of age

2002

HIV is the leading cause of death worldwide for those 15–59

FDA approves the first rapid finger-prick AIDS test

2003

President Bush announces PEPFAR, a $15-billion, 5-year plan to combat AIDS in African and Carribean nations

WHO announces the "3 by 5" initiative, aiming to start providing AIDS drugs to 3 million people in poor countries by 2005

2004

AIDS spreads rapidly in Russia and eastern Europe; according to a UN survey, almost 1% of Russians are HIV-positive

FDA approves a saliva-based AIDS test

A study finds that the rate of HIV prevalence in Uganda has dropped 70% since the early 1990s, due to local prevention efforts

95% of those with AIDS live in the developing world

From 1981 through the end of 2004, more than 20 million people have died of AIDS

2005

FDA begins approving generic AIDS drugs, enabling U.S.-funded programs to provide more cost-effective treatment to poorer nations

Several African nations insist on medication approved by WHO; in response, FDA and WHO agree to share information on generic drugs to expedite their approval

Russian president Putin promised to increase AIDS funding from $5 million in 2005 to at least $100 million in 2006

AZT's patent expires, and FDA approves several generic versions

The number of people living with HIV in 2005 reached its highest level ever-an estimated 40.3 million people, nearly half of them women.

2006

June 5 marks the 25th anniversary of the first journal article (in Morbidity and Mortality Weekly Report) about what would become identified as AIDS, reporting on a set of unusual pneumonia-related deaths among five homosexual men.

A UN report issued the week before has both good news and bad news.

Good news: Many countries have achieved targets set in 2001, reducing the number of new infections and providing antiretroviral therapy to more victims. HIV testing, counseling, and education are all up. In many sub-Saharan countries, more young teens are staying abstinent, and condom use is increasing. And with 126 nations reporting, investigators have more data than ever.

Bad news: Goals for youth education and prevention services aren't being met, those most at risk for AIDS are often not reached, many countries fell far short of all goals, and social issues underlying the spread of AIDS are being ignored.

In short, "A quarter century into the epidemic, the global AIDS response stands at a crossroads. For the first time ever the world possesses the means to begin to reverse the epidemic. But success will require unprecedented willingness on the part of all actors in the global response to fulfil their potential, to embrace new ways of working with each other, and to . . . sustain the response over the long term."

July 2006: The FDA approves the first single-pill, once-a-day AIDS treatment, thereby allowing patients to manage their disease without a complicated regimen of drugs that must be strictly followed to be effective. The pill, called Atripla, is considered an enormous breakthrough in AIDS treatment, and will help prevent the disease from mutating into drug-resistant strains, which occurs when drugs are not taken regularly. Two rival drug companies cooperated in creating the drug.

2007

The World Health Organization revises their figures of the number of people living with AIDS worldwide. In their December 2007 report, the WHO says the number has fallen from 39.5 million to 33.2 million in one year, suggesting that the biggest reason for the 16% decline was improved data collection and more accurate estimates in India and five sub-Saharan African countries.

2008

An international team of researchers announced that new evidence shows the earliest cases of HIV/AIDS circulating between humans occured between 1884 and 1924 in sub-Saharan Africa. Tracking the origin of the virus will help in understanding how it jumped from chimpanzees to humans, as well as increasing our knowledge of the conditions that help viruses spread and how to be better prepared for other epidemics. See this article for more information.

A man in Berlin, Germany seems to be cured of AIDS after doctors gave him transplanted blood stem cells from a person naturally resistant to the virus. Such a treatment is difficult, the patient's immune system must essentially be shut down and restarted with the new stem cells, but first a donor must be found who is a good tissue match for the patient and has a rare genetic mutation, called Delta 32, which is resistant to H.I.V. People who have Delta 32 produce white blood cells in the bone marrow which lack the surface receptors that allow H.I.V. to invade the immune system. Doctors hope this case helps in developing therapies that artificially induce the Delta 32 mutation.

2009

President Obama removes the 22-year-old travel ban that prevented HIV-positive people from entering the United States.

Four million HIV-positive people in developing and transitional countries are receiving treatments, but over 9 million still need immediate treatment.

2011

Elizabeth Taylor, cofounder of the American Foundation for AIDS Research (amfAR), dies. One of the first public personalities to devote time and money toward HIV and AIDS-related projects and charities, she helps raise over $100 million and expand public awareness in her thirty years as an AIDS activist.

In September, gamers of the free online game Foldit create the correct structure of a protein that the virus HIV uses to replicate itself. With this breakthrough, published in Nature as "Crystal structure of a monomeric retroviral protease solved by protein folding game players," not only is the usefulness of the citizen scientist validated, but a real-world scientific problem is also solved. The discovery paves the way for new antiretroviral drugs in the battle against HIV/AIDS.

2012

The medical community announce the "functional cure" of an infant of an HIV infection. In a 2010 birth, a Mississippi baby exposed to HIV was treated aggressively with antiretroviral drugs starting almost immediately after delivery. The baby, now 2 1/2 years old, remains infection free.

2014

In a routine checkup, the "functionally cured" Mississippi baby is found to have HIV antibodies present in her blood, as well as a lowered T-cell count. She will likely remain on antiretroviral therapy for life.

2015

At its 37th meeting, the UNAIDS Board adopted a new 15-year strategy, with the goal of ending the AIDS epidemic by 2030.
