Table 1. Suggested plans of action for isolated populations under 4 scenarios.

	Population growing	Population not growing
Future contact well-organized	Maintain isolation and remote surveillance	Contact recommended
Future contact poorly-organized	Maintain isolation and remote surveillance	Improve protection and contact plan

Policy towards currently isolated populations should be contingent on whether or not the current population is growing (columns) and the prospects for whether or not a future contact will be well-organized (rows).
