Discrepancy Breakdown & Clinical Logic
| Surveillance Parameter | Observed Metric | Epidemiological Mechanism |
|---|---|---|
| Causal Chain Gap | +3 deaths excluded | Death certificates cite immediate organ failure or secondary pneumonia rather than the initial measles contagion. |
| Underreporting Gap | 4,249 uncounted cases | Mild pediatric cases managed at home without serological PCR confirmation or voluntary clinical reporting. |
| Vaccinated Case Paradox | 25.4% of total cases | With 92% community coverage and 78% titer-verified immunity, non-responders in high-uptake regions form ~25% of cases. |
