Eradication programs are usually conducted in stages. As a region gets closer to eradicating a disease, what is true about the rules and regulations for that disease?

• A. They remain constant in all stages
• B. They tend to become less restrictive
• C. They tend to become more restrictive
• D. They vary unpredictably by region

Answer: (B)

Tightening controls as eradication nears is essential to seal the last pockets of transmission. As a region moves toward declaring elimination, authorities emphasize stronger surveillance, mandatory and rapid reporting of any suspected cases, swift investigations, and targeted vaccination to close remaining gaps. Movement restrictions for animals and stricter import/export controls help prevent reintroduction from outside areas. This intensified regulatory framework is what prevents a relapse and provides the robust evidence needed for certification of eradication. While earlier stages may require more general or flexible measures to build capacity, the final phase relies on tightening rules to ensure complete interruption of transmission.
