| Confirmed case |
- Use of an e-cigarette ("vaping") or "dabbing" in the previous 90 days*
|
- Lung opacities on chest radiograph or computed tomography
|
- Exclusion of lung infection based on:
- Negative influenza PCR or rapid test (unless out of season)
- Negative respiratory viral panel
- Negative testing for clinically-indicated respiratory infections (eg, urine antigen test for Legionella and Streptococcus pneumoniae, blood cultures, sputum cultures if producing sputum, and bronchoalveolar lavage if performed)
- Negative testing for HIV-related opportunistic respiratory infections (if appropriate)
|
- Absence of a plausible alternative diagnosis (eg, cardiac, neoplastic, rheumatologic)

| Probable case |
- Use of an e-cigarette ("vaping") or "dabbing" in the previous 90 days*
|
- Lung opacities on chest radiograph (diffuse hazy or consolidative opacities) or computed tomography (ground glass or consolidative opacities)
|
- Infection identified via culture or PCR, but clinical team believes this infection is not the sole cause of the underlying lung injury
- OR
- Minimum criteria to rule out pulmonary infection not met (testing not performed) and clinical team believes infection is not the sole cause of the underlying lung injury

- Absence of a plausible alternative diagnosis (eg, cardiac, neoplastic, rheumatologic)
