This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by Post COVID-19 condition (long COVID): For health professionals. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Confirm a compatible post-COVID time course while investigating new, severe or alternative cardiopulmonary, neurologic and systemic diagnoses.
  • Assess symptom burden, post-exertional exacerbation, cognition, sleep, autonomic symptoms, mental health and functional impact.
  • Use individualized rehabilitation and pacing with goal-based follow-up; avoid a one-size-fits-all fixed exercise progression.
  • New symptoms after infection still require assessment for unrelated and potentially treatable diagnoses.

Practical assessment and management workflow

1
Document infection timing, symptom clusters, exertional response, function, work and mental health.
2
Measure orthostatic observations, oxygenation and targeted cardiopulmonary or laboratory tests based on symptoms.
3
Agree on symptom-specific rehabilitation, pacing and treatment without forcing activity through post-exertional worsening.
4
Review trajectory and coordinate primary, rehabilitation and specialist services for persistent disability.

Safety, red flags and urgent escalation

  • Escalate new chest pain, syncope, resting hypoxemia, focal neurology or severe psychiatric risk.
  • Investigate pulmonary embolism, myocarditis or other acute disease when the presentation warrants it.
  • Avoid promising an unproven drug or supplement as disease-modifying treatment.
