One of my favorite FSG moments was 4 years ago in Karachi, Pakistan conducting research regarding potential new diarrheal treatments for children. My colleague and I were in a small crowded urban clinic in a slum, surrounded by mothers holding their babies. One mother brushed her headscarf from her eyes and placed her 2 month old baby girl in my arms asking whether there were medicines that could make her well. It was rewarding to be able to say yes, and talk about oral rehydration salts that could ensure her little girl stayed hydrated while she regained her strength. But the answer in many cases isn’t a “yes”. In many cases the drugs that patients require are still under development, or are too expensive, or are protected by patents, preventing them from being available to poor populations.
