For the next 18 months, Bloomberg Philanthropies, in partnership with the World Health Organization and Vital Strategies, will be working with cities across the globe to tackle the different factors contributing to noncommunicable diseases. [...] The program will be very much city-driven; local governments will have leeway on what intervention to prioritize and work on. WHO and Vital Strategies, meanwhile, will provide assistance and help them make use of data to guide their decisions as well as in developing their work plans.
