World Health Day took place the week of 7 - 11 of April 2010. In the past, World Health Day has focused on issues such as the health workforce crisis, international health security, climate change, and resiliency and safety of health facilities and workers during emergencies. This year's World Health Day focuses on urbanization and health. The campaign organized events surrounding the theme "1000 cities - 1000 lives", calling on cities to open up their streets for health actitivities.
