In the rapid test and slaughter approach for AI H5 outbreaks, the intended response time is approximately how long?

• A. 24 hours
• B. 48 hours
• C. 72 hours
• D. 1 week

Answer: (A)

The main idea is that speed is essential to stop spread: by rapidly identifying infected flocks and removing them, you cut off the virus’s opportunities to contaminate buildings, equipment, and people and to move to neighboring farms. In an H5 avian influenza outbreak, the virus can shed quickly and transmit through direct contact or via fomites, so the sooner culling and disposal happen, the fewer secondary infections occur. A 24-hour window is targeted because it allows rapid on-site or near-site testing, immediate mobilization of depopulation teams, and prompt disposal and disinfection. This tight timeline minimizes environmental contamination and helps reestablish control faster. Extending beyond 24 hours increases the chance of further spread, which can escalate to more farms and greater losses, while waiting a week would be far too long for a highly contagious event.
