Since the beginning of the COVID-19 pandemic and as new information has become available, the Centers for Disease Control and Prevention (CDC) and local governments have continuously revised their isolation and quarantine requirements and recommendations. The constantly changing guidelines and executive orders makes it difficult to keep track of the changes and their applicability to different circumstances. Accordingly, below we summarize the progression and current status of CDC recommendations and Puerto Rico mandates and provide a brief timeline on the modification of isolation and quarantine requirements since the start of Puerto Rico’s COVID-19 state of emergency. Finally, we summarize the recently amended quarantine and isolation provisions for air passengers arriving in Puerto Rico.
