Finding F-0443
“Ventilation engineering decreased the maximum CO2 levels from 3204 ± 50 ppm to 591-603 ppm.”
Structure
- Factor
- Carbon dioxide (CO₂)
- Intervention
- Ventilation
- Population
- university students and staff (outbreak contacts)
- Setting
- university classroom, TW
- Study design
- outbreak investigation with a contact cohort: 27 tuberculosis cases and 1665 contacts in underventilated university buildings in Taiwan, indoor CO2 measured before and after ventilation engineering, incidence of TB among contacts analysed with adjustment for contact investigation and latent TB infection treatment (class 3)
- Effect
- other
- Sample
- 1665 participants
- Caveat
- maximum level recorded as measure other; the value after is printed as a range and sits in extra
