The 3 category classifications
Details
aetiological:
Confirmed SARS-CoV-2 - implies Infective
No evidence SARS-CoV-2 - implies Infective but not confirmed as SARS-CoV-2
Non-infective - presumed non infective
clinical presentation:
Pneumonia - implies Infective
NP-LRTI - implies Infective
No evidence LRTI (include CRDE and HF)
Some cases do not get a clinical presentation in this. Typically they are people who have an infective cause, but LRTI and pneumonia have been excluded. These could be URTI and or incidental COVID cases.
