Tuberculosis (TB) is the biggest preventable killer in the world today. Despite a sound treatment and strategy in place, 2 million people die of the disease every year. Communications has an important part to play in helping to eradicate TB as a public heath issue over the next 50 years. This is why the 24th March has been designated as World TB Day, to help spread the message loud and clear to the world community. We worked with the Stop TB Partnership to develop the theme and all communications materials for World TB Day 2007, created in 7 languages and spread to all corners of the globe.
