All the swine flu ones are great, and you should rightly ask them.
However, they detract from the one great question which is why are most of the medical donations that are given to Mexico given as 'charity relief' which means that companies can 'donate' vast amounts of almost out of date and extremely difficult to get rid of chemical medicines which the donating companies have no use for and don't want to pay to get disposed of properly to hospitals there. These hospitals then have to accept ridiculous medicines they have no use for, store them, and then pay to have them safely disposed of.
