Discontinuation of Transmission-Based Precautions and Disposition of Patients with COVID-19 in Healthcare Settings (Interim Guidance)

The resolution to discontinue Transmission-Based Precautions for sufferers with confirmed SARS-CoV-2 an infection ought to be made utilizing a symptom-based technique as described beneath.  The time interval used will depend on the affected person’s severity of illness and if they’re severely immunocompromised.1 Meeting standards for discontinuation of Transmission-Based Precautions isn’t a prerequisite for discharge from a healthcare facility.

A test-based technique is now not really helpful (besides as famous beneath) as a result of, within the majority of instances, it ends in extended isolation of sufferers who proceed to shed detectable SARS-CoV-2 RNA however are now not infectious.

Symptom-Based Strategy for Discontinuing Transmission-Based Precautions.

Patients with mild to moderate illness who should not severely immunocompromised:

  • At least 10 days have handed since signs first appeared and
  • At least 24 hours have handed since final fever with out using fever-reducing drugs and
  • Symptoms (e.g., cough, shortness of breath) have improved

Note:  For sufferers who’re not severely immunocompromised and who had been asymptomatic all through their an infection, Transmission-Based Precautions could also be discontinued when at the least 10 days have handed for the reason that date of their first constructive viral diagnostic take a look at.

Patients with severe to critical illness or who’re severely immunocompromised1:

  • At least 20 days have handed since signs first appeared and
  • At least 24 hours have handed since final fever with out using fever-reducing drugs and
  • Symptoms (e.g., cough, shortness of breath) have improved

Note:  For severely immunocompromised1 sufferers who had been asymptomatic all through their an infection, Transmission-Based Precautions could also be discontinued when at the least 20 days have handed for the reason that date of their first constructive viral diagnostic take a look at.

As described within the Decision Memo, an estimated 95% of severely or critically unwell sufferers, together with some with extreme immunocompromise,  now not had replication-competent virus 15 days after onset of signs; no sufferers had replication-competent virus greater than 20 days after onset of signs.  Because of the dangers for transmission and the variety of sufferers in healthcare settings in danger for extreme sickness if contaminated with SARS-CoV-2, a conservative strategy was taken when assigning period of Transmission-Based Precautions.  However, as a result of the vast majority of severely or critically unwell sufferers now not look like infectious 10 to 15 days after onset of signs, services working below disaster requirements of care may select to discontinue Transmission-Based Precautions at 10 to 15 days, as an alternative of 20 days, with the intention to maximize sources for these earlier of their scientific course who’re at highest danger for being a supply of transmission.

Test-Based Strategy for Discontinuing Transmission-Based Precautions.

In some situations, a test-based technique could possibly be thought-about for discontinuing Transmission-based Precautions earlier  than if the symptom-based technique had been used. However, as described within the Decision Memo, many people may have extended viral shedding, limiting the utility of this strategy. A test-based technique is also thought-about for some sufferers (e.g., those that are severely immunocompromised1) in session with native infectious illnesses specialists  if considerations exist for the affected person being infectious for greater than 20 days.

The standards for the test-based technique are:
