Correct Answer » B Explanation |
 |
Polio is under intensive global surveillance as part of the Global Polio Eradication Initiative (GPEI).
- Includes Acute Flaccid Paralysis (AFP) surveillance worldwide
- Mandatory reporting and lab confirmation
- Coordinated by WHO across countries
Thus, polio is the classic example of a disease under international surveillance.
Explanation of Other Options:
A. Hepatitis
- Surveillance exists but not as strict or globally coordinated as polio eradication programs
C. Tuberculosis (TB)
- Monitored globally (WHO programs), but not under strict eradication-level surveillance like polio
D. Leprosy
- Controlled under national programs; not under active global eradication surveillance
International Surveillance Programs:
- Polio:
- Global eradication target disease
- AFP surveillance is key
- Lab-based confirmation (stool samples)
- Zero-case reporting system
- Other Diseases under International Concern:
- Influenza (pandemic surveillance)
- COVID-19 (recent global surveillance)
- Cholera (epidemic-prone disease monitoring)
