WHO campaigns

Mark these days for health in your calendar

Global public health campaigns offer great potential to raise awareness and understanding about health issues and mobilize support for action, from the local community to the international stage.

There are many world days observed throughout the year related to specific health issues or conditions – from Alzheimer's to zoonoses.

However, WHO focuses particular attention on the seven days and one week that WHO Member States have mandated as "official" global public health campaigns. These are:

  • World TB Day, 24 March
  • World Health Day, 7 April
  • World Immunization Week, last week of April
  • World Malaria Day, 25 April
  • World No Tobacco Day, 31 May
  • World Blood Donor Day, 14 June
  • World Hepatitis Day, 28 July
  • World AIDS Day, 1 December

Join in for better health

Whether you are taking the kids to be vaccinated, talking to students on the devastating health effects of tobacco, organizing a mobile blood collection in your community, or contributing to the online conversation through social media, you can play a part in these worldwide efforts to create a healthier world.

This site brings together information on the eight official campaigns on which we focus. Leading up to each day, this is where you will find background information, graphics, multi-media links, facts and figures that help highlight the issues and focus global attention on today’s major public health challenges.
