Well, before we leave AIDS, I think the point that was made around children's formulas, around the appropriate dosage and treatment for children, around the whole question of second- and third-round treatment, is that these are the sorts of things we're still beginning to understand, and they're really important.
The fact is that for many people in the south, we're talking about.... Just to state the obvious for a moment, these are people who earn less than a dollar a day in income. There isn't a medical system. For them, the biggest barrier to health care is the cost of the drugs themselves. A lot of them are purchasing these privately, on a market, through a market system. A range of issues, including, as I say, cancer, diabetes, or TB treatments--TB tends to get caught through the medical care system, but other things not necessarily—can have a phenomenal impact on people's lives, livelihoods, and communities.
You can cite all sorts of examples of where, because of pressure on governments in the south, the cost of drugs is actually increasing significantly--in Peru, in Bolivia, in Colombia, in countries in sub-Saharan Africa. The accessibility of drugs has been significantly retarded as a consequence of those pressures and the impact of regional trade agreements.
