What is the difference between quarantine, isolation, and restriction of movement (ROM)?

ROM is an umbrella term for any Restriction of Movement of an individual or group to prevent or diminish the transmission of a communicable disease. The following are categories of ROM:

  • Isolation: You have COVID, or are reasonably suspected of having COVID, because you are displaying symptoms. Isolation is the physical separation of an individual or group for a minimum of 14 days in an isolation facility or residence following the onset of symptoms.
  • Quarantine: You may have been exposed to COVID. Quarantine is the precautionary separation of those who may have been exposed to COVID-19, but may not be ill. This includes newly arrived PCS personnel or those returning from designated ‘High Risk’ areas. These personnel are not allowed to leave their quarantine location until the completion of 14 days. One cannot test out of quarantine.  If an individual in quarantine tests positive or displays symptoms, they go into isolation for 14 (more) days.
  • Unit-Directed: These are temporary restrictions on non-essential errands for a period of time, as specified by a unit commander. Unit-directed ROM is used to limit movements to enable contact tracing and results of random testing within a formation, or to preserve combat power ahead of a deployment or exercise.
  • Social distancing: You have cold or flu-like symptoms. You tested negative for COVID. You have not been exposed to a COVID case. You do not need quarantine or isolation. However, during the COVID pandemic, you should not go to work or school while sick with a cold or the flu. Once better, no additional testing is required, and you can return to work/school.
