• The importance of information technology (IT) support
• New research findings
Foci Investigation within 7 days • Complexity and difficulties during evaluation of local transmission risk
• Respecting the 7 days timeline
• IRS and RACD in potential active/active foci
• Acceptance of actions by population
• Limited quality control of focus investigation
