Gregory Pappas and Omar Khan have signed an agreement with American Public Health Association to produce a book titled “Megacities and Health.” That book will bring together a number of authors to present a state-of-the-art look at the health issues facing the 24 largest urban places on the globe. Megacities are places with populations of over ten millions. There is currently no comprehensive text on the health in megacities. http://megacitiesandhealth.blogspot.com/
