Which disease is listed as one that may lead to apprehension or detention to prevent spread?

• A. Influenza
• B. Measles
• C. Mumps
• D. Smallpox

Answer: (D)

Apprehension or detention to prevent spread is invoked when a disease is so highly contagious and dangerous that voluntary isolation may not be enough to protect the community. Smallpox fits that description because it spreads easily through respiratory droplets and contaminated objects, can be transmitted before symptoms are obvious, and historically carried a high risk of severe illness and death. Because of these factors, public health authorities have had the legal authority to detain individuals suspected of having smallpox to stop transmission and protect others. The other diseases listed are contagious and managed with standard public health measures like vaccination and isolation, but they do not generally necessitate detention to the same extent as smallpox.
