Nations around the world have stepped-up Ebola screening procedures for passengers coming from West Africa in recent weeks, but new research from Toronto's St. Michael's Hospital suggests more needs to be done at the source of the virus to prevent it from spreading further. 

Isaac Bogoch, a researcher with the University Health Network told CBC News on Monday that Canada and other wealthy countries should be "pouring resources" into the most affected areas, such as in Liberia and Guinea. What's needed is more doctors, nurses and stricter screening protocols at airports in that region. 

"It's easier to screen in three airports than the infinite number of airports people could land in at their final destination once they've made their connection," Bogoch said.
