The World Health Organization, part of the United Nations, sets standards for global health. (See their Millennium Development Goals.) WHO provides leadership, direction, and training for worldwide health projects and monitor projects to make sure they meet minimum standards.
Their website is filled with facts and statistics about just about every worldwide health issue imaginable, from tobacco to influenza to cholera.
- WHO has a podcast. A recent one was on cholera in Zimabawe.
- WHO sponsors conferences. An upcoming on is on Children's Health and the Environment.
- They write fact sheets. For example, see Bottled drinking water.
A pretty awesome organization. Check it out.
