Key interventions summary.
| INTERVENTION | EVIDENCE | EFFICACY | FEASIBILITY | PROJECTED IMPACT |
|---|---|---|---|---|
| HPV vaccination | High | 90%–100% vs HPV 16/18 | Moderate | 160 K orphans prevented/year by 2050 |
| HPV screening | High | 60%–80% reduction | Moderate | 100 K orphans prevented/ year |
| VIA + cryotherapy | Moderate | 25%–35% reduction | High | 50 K orphans prevented/ year |
| Breast early detection | Moderate | 20%–30% mortality reduction | Moderate‑Low | 50–70 K orphans prevented/ year |
| Breast comprehensive treatment | High | 85%–90% 5‑yr survival | Low | 130 K orphans prevented/ year |
| UHC + financial protection | Moderate | Improves treatment completion | Context‑dependent | Enables all interventions |
| Cash transfers (orphans) | High | Improves education, health | Moderate | Mitigates orphanhood impact |
| Psychosocial support | Moderate | Reduces mental health burden | High | Long‑term well‑being |
[i] Evidence levels: High = RCTs/systematic reviews; Moderate = observational/cohort; Low = limited data.
[ii] Feasibility: Based on resource requirements, infrastructure, and implementation complexity.
