The international medical NGO, Medecins Sans Frontieres (MSF), is urging G8 nations and the UN to push for speedy delivery of the cheapest and latest anti-AIDS drugs to developing countries. MSF stressed that this was vital to head off a looming supply and cost crisis, because "access to newer drugs is increasingly critical, as the growing number of people with HIV/AIDS currently on treatment will inevitably develop resistance to first-line treatments".
