health Themes of World Health Days 2006: Working together for health In 2006, World Health Day was devoted to the health workforce crisis, or chronic shortages of health workers around the world due to decades of underinvestment in their education, training, salaries, working environment and management. The day was also meant to celebrate individual health workers – the people who provide health care to those who need it, in other words those at the heart of health systems. The Day also marked the launch of the WHO's World Health Report 2006, which focused on the same theme. The report contained an assessment of the current crisis in the global health workforce, revealing an estimated shortage of almost 4.3 million physicians, midwives, nurses and other health care providers worldwide, and further proposed a series of actions for countries and the international community to tackle it. The World Health 2008: Protecting health from the adverse effects of climate change In 2008, World Health Day focused on the need to protect health from the adverse effects of climate change and establish links between climate change and health and other development areas such as environment, food, energy, transport. The theme "protecting health from climate change" put health at the centre of the global dialogue about climate change. WHO selected this theme in recognition that climate change is posing ever growing threats to global public health security. 2009: Save lives. Make hospitals safe in emergencies World Health Day 2009 focused on the safety of health facilities and the readiness of health workers who treat those affected by emergencies. Health centres and staff are critical lifelines for vulnerable people in disasters – treating injuries, preventing illnesses and caring for people's health needs. Often, already fragile health systems are unable to keep functioning through a disaster, with immediate and future public health consequences. For this year's World Health Day campaign, WHO and international partners underscored the importance of investing in health infrastructure that can withstand hazards and serve people in immediate need, and urged health facilities to implement systems to respond to internal emergencies, such as fires, and ensure the continuity of care. 2010: Urbanization and health With the campaign "1000 cities, 1000 lives", events were organized worldwide during the week starting 7 April 2010.
