Which disease is included in the detainee list under the Public Health Service Act?

• A. Measles
• B. Malaria
• C. Rabies
• D. Diphtheria

Answer: (D)

The key idea here is the federal authority to detain people who have or may have diseases that pose a public health risk, to prevent their spread. The detainee list under the Public Health Service Act defines which diseases trigger that detention authority. Diphtheria is included on that list because it is highly contagious and can cause serious illness quickly, especially in vulnerable groups. Because it can spread rapidly through respiratory droplets, public health officials need the option to detain and isolate individuals who may be infectious until they are diagnosed and no longer pose a transmission risk.

Measles, while also highly contagious, is not on the formal detainee list used to authorize detention under this act. Malaria and rabies are managed through other public health measures rather than a detention framework aimed at preventing rapid spread from an infectious person. Therefore, diphtheria is the disease among the options that fits the detainee-list criterion.
