Elsea, American Law Division Abstract: This report provides an overview of federal and state public health laws as they relate to the quarantine and isolation of individuals, a discussion of constitutional issues that may be raised should individual liberties be restricted in a quarantine situation, and federalism questions that may arise where federal and state authorities overlap.
