3. §70.6 Apprehension and Detention of Persons With Quarantinable Communicable Diseases

Through this NPRM, HHS/CDC has proposed to change the text of this provision.

We have modified “infected with a quarantinable communicable disease” to clarify, consistent with the statute's requirements, that the individual must be in the “qualifying stage” of a quarantinable communicable disease, which we also define. We did this to better align our regulations with the Public Health Service Act which authorizes the “apprehension and examination of any individual reasonably believed to be infected with a [quarantinable communicable] disease

4. §70.10 Public Health Prevention Measures To Detect Communicable Disease
. . . During a public health risk assessment, if facts or circuмstances are discovered that give rise to a reasonable belief that the individual is infected, as defined under this NPRM, with a quarantinable communicable disease in its qualifying stage, CDC may authorize the quarantine, isolation, or conditional release of the individual. Similarly, an individual's refusal to be screened may result in quarantine, isolation, or conditional release, but only if sufficient facts and circuмstances otherwise exist giving rise to a reasonable belief that the individual is infected with a quarantinable communicable disease in its qualifying stage.
