In this Huffington Post “Impact” blog post, Melinda Gates, co-chair of the Bill & Melinda Gates Foundation, writes that she will be visiting Bangladesh to “lear[n] even more about two of the biggest killers of children — pneumonia and diarrhea,” and says “Bangladesh has made incredible progress in recent years, reducing the number of childhood deaths by 65 percent since 1990.” She writes, “As I reflect back on what I learned this year about the progress and the challenges in women’s and children’s health, I’m struck by the fact that we don’t need to wait for the solutions,” including “[t]hings like life-saving vaccines, contraceptives, healthy practices for mothers and newborns and good nutrition.”

Gates concludes, “I want to see cost-effective tools for saving lives in as many places as possible — and I want to see social media help make that happen by continuing to foster conversation and dialogue among all of us who care so deeply about these issues,” and calls on people to submit questions or comments through several social media networks (1/4).
