asia, because this continent contains the greatest proportion of the world’s population
canada, because this country has the best ranked health care in the world

Explanation:

Ebola virus was first identified near the Ebola River in sub - Saharan Africa. Populations in areas with a history of Ebola exposure are more likely to have developed protective mutations. The United States and Canada have less natural exposure history. Asia, while populous, has no direct link to the origin of Ebola for such mutation - protection research.
