Could Coca Cola heal the world? Or Standard Chartered Bank or Chevron oil, for that matter? These giant corporations have money and skills. They do business in difficult, hard-to-reach places. They make things happen. So how much could be achieved if they put their efforts into global health? John Tedstrom, president and CEO of the Global Business Coalition on HIV/Aids, Tuberculosis and Malaria, spends his time urging and helping them to do just that...So in western Kenya, the GBC has a project going which is intended to reach two million people mostly in rural settings with home-based testing and counseling...The hand of big business is clear from the sheer efficiency of the programme...Over 200 companies are now signed up to the GBC, some of which end up collaborating with their competitors...[Tedstrom] wants more companies to get involved, especially from under-represented sectors, such as oil and gas services companies like Schlumberger and Fluor.
