COVID-19 Questions & Myths


A very small number of patients are admitted for other care and are discovered to have COVID-19 at or after admission.

Based on emergency room diagnoses and admission data in Alberta, the majority of patients are admitted with severe viral pneumonia requiring oxygen treatment or admission to ICU for mechanical ventilation.  A study in the Canadian Medical Journal on the first wave found no COVID-19 cases in 1814 people admitted to three Alberta hospitals for non-COVID-19 causes.
