Revised List of Quarantinable Communicable Diseases

This executive order amends the list of quarantinable communicable diseases to include severe acute respiratory syndromes (SARS-like diseases) that pose pandemic potential or high mortality/morbidity risk, explicitly excluding influenza. The update expands federal quarantine authority under Section 264(b) of Title 42 to cover emerging respiratory threats beyond the original 2003 list.
