Dr. Junior Bazile, a Haitian physician, scrolled through his handheld device while walking through the wards of a district hospital in rural Malawi. He had recently commented on a discussion on GHDonline.org regarding critical gaps in the diagnosis and treatment of drug resistant tuberculosis. Hours later, he was reading detailed replies from a tuberculosis advisor in Azerbaijan and a medical officer at the World Health Organization. They shared recent publications and discussed the best strategies for how to ensure that patients are treated swiftly and their families and communities protected.
