There are two major problems with the list: First, there are a number of diseases which mainly occur in developing countries. Many people there cannot afford to pay high prices for drugs, which means pharmaceutical companies are not interested in developing new drugs for such diseases.

Examples for the second kind of drugs are those used to treat AIDS.
