The latest dispatch from the war on AIDS brings good news. At 5.25m, the number of people in poor and middle-income countries who were being treated for HIV infection at the end of 2009 was up 30% from the end of 2008. Eight countries achieved coverage of 80% or better and 21 others covered more than half of those in need. Though the new figure still represents only about a third of those who could benefit, the rate of increase is impressive.
