Abstract:
Almost everyone from Africa or Asia needs a visa to enter Spain--although citizens of the U.S. and over 50 other countries do not. Many delegates from developing countries have had great difficulties getting a Spanish visa to attend the big international conference in Barcelona; we do not know how many were kept away as a result. In addition, we look at another access and solidarity issues, the price of the international AIDS conferences--and show that other large meetings can make a profit on a tenth the price.
