Add transparent points for symptoms commonly discussed with COVID-19 and other viral respiratory illnesses: severe breathing difficulty, chest pain, confusion, bluish discoloration, optional room-air SpO₂ band, inability to keep fluids down, fever/chills, cough or severe sore throat, and marked weakness. An emergency pattern flag mirrors familiar “call 911 / emergency services” teaching themes. This is not laboratory diagnosis, not WHO clinical severity staging, and not a substitute for your clinician or local public health line. More on medical & health calculators.

Lower burden on this checklist: continue routine monitoring; seek care if symptoms escalate, new red-flag signs appear, or you cannot maintain fluids.
Pulse oximeters can misread with cold fingers, nail polish, or poor fit. Follow device instructions and local public health testing guidance—this page does not tell you whether you have COVID-19.
Severe dyspnea receives the largest single-item weight to reflect hypoxic respiratory failure themes in acute viral illness education.
Chest pain triggers the emergency pattern because myocarditis, pulmonary embolism, and ACS remain in the differential during viral seasons—not only “lung infection.”
Altered mental status and cyanosis are high-consequence findings in classroom triage drills and align with common emergency-call messaging.
If the user selects “not measured,” no SpO₂ points are added—emphasizing that absence of a number is not absence of risk when symptoms are severe.
Dehydration and systemic inflammatory symptoms add moderate points to support discussion of hydration, antipyretics per label, and when to escalate care.
Influenza, RSV, metapneumovirus, and bacterial pneumonia can overlap; the checklist is symptom-first for education rather than pathogen-specific scoring.
Default demo: fever and cough/sore throat only → total 3 → mild burden on this page (no emergency pattern).
If no emergency pattern: total 0–3 mild; 4–8 moderate; 9+ high. Any emergency pattern item forces the emergency teaching tier regardless of other points.
Boolean items add fixed point weights; the SpO₂ dropdown adds 0, 4, or 10 points. The emergency pattern flag uses logical OR across the highest-acuity items so learners can separate “high numeric score” from “hard stop emergency themes.”
Many health agencies have published lists of symptoms that warrant emergency care. This calculator is an independent teaching scaffold and may not match every jurisdiction’s current wording or thresholds.
