swine flu in resource limited areas

May I please learn from the esteemed members?

Which set of patients should be tested for swine flu if the disease is present in resource limited areas as in India?
What test would be most appropriate for such settings?
Amongst those who test positive,who would be true candidates for antiviral therapy in such areas?
What measures apart from possibly hand washing truly help prevent spread when these patients report to busy outpatients?
