Disease outbreaks continue to have severe consequences across the globe, affecting populations near the source of the outbreak and potentially affecting others due to population movements. In today’s interdependent and interconnected world, there is a need for robust and resilient outbreak alert and response system for effective and timely action.

  • Real-time risk assessment and information sharing for decision-making;
  • Response strategy and planning;
  • Rapid access to subject matter experts;
  • Effective data management;
  • Risk communication and social mobilisation;
  • Efficient field logistical and operational support;
