Ibrahim Khalil, senior program officer at the Bill & Melinda Gates Foundation on the Enteric & Diarrheal Diseases team, highlights Cryptosporidium in the Foundation’s “Impatient Optimists” blog. “Cryptosporidium (Crypto) is an intracellular protozoan parasite that causes mild to severe infection known as cryptosporidiosis (crypto). Those infected with Crypto can develop persistent diarrhea and face risk of death from dehydration. … While Crypto presents many challenges, the Foundation is committed to reducing morbidity and mortality of children infected by this disease. Our goal is to accelerate development of new interventions, such as treatment or vaccines that will address the burden of this disease,” Khalil writes, listing three key goals to the Foundation’s approach (3/17).
