True/False: In an outbreak, exotic pet birds can be removed from isolation immediately after negative tests.

• A. True
• B. False
• C. Not enough information
• D. It depends on the species

Answer: (B)

Tests only provide a snapshot in time. After a negative result, an exotic pet bird may still be incubating the infection or may shed later, and test sensitivity is not perfect. Because many pathogens have an incubation period during which an animal appears healthy while becoming contagious, releasing a bird from isolation immediately after a negative test can allow transmission to continue. The safer approach is to keep birds in isolation for a period that matches the disease’s incubation and contagious window and to use serial testing or continued clinical monitoring as guided by outbreak protocols. Only after completing the recommended quarantine and (if used) multiple confirmatory tests should removal from isolation be considered.
