- Collected air and surface samples in a hospital caring for critical and severe COVID‐19 cases from common areas and areas proximal to patients.
- Of the 218 ICU samples, an air sample contained SARS‐CoV‐2 RNA. Of the 182 isolation ward samples, nine contained SARS‐CoV‐2 RNA.
- Isolation wards may pose greater risks to healthcare workers and exposure risks remain with clinically improved patients, weeks after their initial diagnoses.
- As these patients had serum antibodies, further studies may be warranted to study the utility of serum antibodies as a surrogate of viral clearance in allowing people to return to work.
