World Vision says the involvement of major businesses has helped contain the spread of tuberculosis in Papua New Guinea.
World Vision's country director, Curt von Boguslawski, says PNG is beginning to get on top of what has been one of its biggest killers.
He says a key factor in this has been the positive attitude taken by a number of business corporates.
Mr von Boguslawski says they have encouraged these businesses to take a pro-active stance instead of sacking employees who get sick and fail to turn up for work.
"Rather than doing that, we really advocate that they become treatment supporters themselves. We have seen it with the Toyota Corporation here, Ela Motors, that in all 16 of their dependencies around the country, they now have a programme on board where they train treatment supporters and they help the community they are operating in to fight TB. ."
