On July 3 from 1 p.m. to 3 p.m. UK time (8 a.m. to 10 a.m. EDT), The Guardian’s “Global Development Professionals Network” will host an online conversation addressing the challenges to treating artemisinin-resistant malaria and preventing the spread of the disease. “[W]hat are the ways to tackle drug resistant malaria? What would be the global health costs if artemisinin becomes ineffective? Should all stakeholders now focus on strengthening prevention as opposed to treatment?” the newspaper asks. To join the conversation, “or give your views before the chat, e-mail globaldevpros@guardian.co.uk,” and follow the conversation’s Tweets using #globaldevlive, the newspaper notes (Scott, 6/27).
