The Centers for Disease Control and Prevention (CDC), a component of the U.S. Department of Health and Human Services (HHS), is hereby issuing this Public Health Determination and Order regarding suspending the right to introduce certain persons from countries where a quarantinable communicable disease exists (Public Health Determination and Termination). This public health determination and termination terminates the order suspending the right to introduce certain persons from countries where a quarantinable communicable disease exists issued on August 2, 2021, and all related prior orders issued pursuant to the authorities in sections 362 & 365 of the Public Health Service (PHS) Act and the implementing regulation. This termination will be implemented on May 23, 2022. The August order continued a suspension of the right to introduce "covered noncitizens," as defined in the order into the United States along the U.S. land and adjacent coastal borders. The August order states that CDC will reassess at least every 60 days whether the order remains necessary to protect the public health. Based on the public health landscape, the current status of the COVID-19 pandemic, and the procedures in place for the processing of covered noncitizens, taking into account the inherent risks of transmission of SARS-CoV-2 in congregate settings, CDC has determined that suspension of the right to introduce such covered noncitizens is no longer necessary to protect U.S. citizens, U.S. nationals, lawful permanent residents, personnel and noncitizens at the ports of entry and U.S. Border Patrol states, and destination communities in the United States. This termination will be implemented on May 23, 2022, to enable the Department of Homeland Security to implement appropriate COVID-19 mitigation protocols, such as scaling up a program to provide COVID-19 vaccinations to migrants, and prepare for full resumption of regular migration processing under Title 8 authorities. Until that date, it is CDC's expectation that DHS will continue to apply exceptions outlined in the August order to covered noncitizens as appropriate, including the exception based on the totality of an individual's circumstances on a case-by-case basis.
