Several passengers on the Malaysia Airlines plane shot down over eastern Ukraine on Thursday were headed to the biennial International AIDS Conference in Melbourne, Australia.* It is one of the largest research conferences in the world, begun in 1985, where scientists, advocates, and policymakers gather to share the latest progress in the battle against the ravaging disease.
Among the many lost were two giants of the HIV research community. “Both Joep Lange and Jacqueline van Tongeren meant a lot to us, as colleagues and as friends,” an anguished Brandon O’Dell of the Amsterdam Institute for Global Health and Development told me. Lange was once the president of the International AIDS Society, which organizes the conference. Van Tongeren, his partner, was a nurse and advocate and head of communications for the AIGHD.
The motives and details of what happened to MH17 remain yet unclear. The missile attack killed 298 people. (The initial estimate of 295 was increased when officials added lap-held infants.)
For those involved in the global fight against AIDS, pain and loss are acute. Many took to Twitter to express their shock, the depth of such sadness plainly captured even in 140 or fewer characters.
This is tragic news for a field that has seen such progress, much of it thanks to the work of Lange, van Tongeren, and their colleagues. New AIDS infections have been on the decline globally, shrinking by 38 percent since 2001, according to new figures from the United Nations. Fewer children are infected with AIDS, and fewer people living with HIV are succumbing to disease. The work by humanitarians such as Lange, who founded the PharmAccess Foundation, a charity that helps improve drug access in sub-Saharan Africa, has helped increase the number of people in low- and middle-income countries on antiretroviral drug therapy. In just 10 years, the number treated in these countries climbed from 300,000 in 2002 to 9.7 million in 2012.
The gloom cast over these hopeful circumstances by the MH17 deaths makes this year’s AIDS conference and the work of AIDS researchers all the more important. “In recognition of our colleagues’ dedication to the fight against HIV/AIDS, the conference will go ahead as planned and will include opportunities to reflect and remember those we have lost,” the International AIDS Society said in a statement.
“Everyone here is completely committed to carrying out the vision that Joep and Jacqueline have for combating AIDS,” O’Dell told me. Though the 2014 International AIDS Conference, which runs from July 20 to July 25, will no doubt be a muted and somber affair, there are hope and dignity in the resolve of those carrying on the mission of those who died in the attack. As Dean Beck, a local journalist in Melbourne covering the conference, put it to me, his voice breaking over the telephone line: “The HIV community knows all too much about grief. But whatever the loss, it is a unified tragedy that will propel us forward.”
*Correction, July 20, 2014: This article originally misstated that about 100 passengers killed on MH17 were flying to the International AIDS Conference, an estimate that was widely reported before the release of the passenger manifest. After more information was released, the International AIDS Society reported that six delegates were among those killed. (Return.)
Update, July 18, 1:32 p.m.: Speaking Thursday about MH17, President Obama held up these researchers as examples of men and women who remind us of ‘the humanity we hold in common.’ ” His remarks about the researchers are below.
