🔴 Healthcare Strain
High cases, hospitals near capacity
💉 High Immunity
High vaccination, endemic phase
⚠️ New Variant
Rising cases, immune evasion concerns
🏘️ Rural Area
Lower density, limited healthcare

Understanding Reopening Metrics
Safe reopening requires monitoring multiple indicators simultaneously. No single metric tells the whole story - combined assessment of transmission, healthcare capacity, testing adequacy, and immunity levels guides evidence-based decisions.
| Metric | Green | Yellow | Red |
| Cases/100k/week | <10 | 10-50 | >50 |
| Test Positivity | <3% | 3-10% | >10% |
| R-effective | <0.9 | 0.9-1.1 | >1.1 |
| ICU Occupancy | <60% | 60-80% | >80% |
| Vaccination | >80% | 60-80% | <60% |
Phased Reopening Framework
Phase 1: Stay at Home
Severe restrictions - essential services only
Economic: Severe - 30-40% GDP reduction
Phase 2: Limited Operations
Gradual reopening with significant restrictions
Economic: Moderate - 15-25% GDP reduction
Phase 3: Cautious Reopening
Expanded operations with precautions
Economic: Mild - 5-15% GDP reduction
Key Considerations
Equity in Reopening
- • Essential workers need priority protection
- • Underserved communities need testing access
- • Children's education is a public health priority
- • Mental health impacts of restrictions
Economic Considerations
- • Balancing health and livelihoods
- • Targeted support for affected sectors
- • Long-term sustainability of measures
- • Recovery planning timeline
