WHO Roadmap on good indoor ventilation in the context of COVID-19

The World Health Organization (WHO) developed and published a roadmap on how to improve ventilation in indoor spaces in the context of COVID-19. The roadmap is divided into three settings – health care, non-residential and residential spaces – and takes into account different ventilation systems (mechanical or natural). The roadmap is aimed at health care facility managers, building managers, as well as those members of the general public who are providing home care or home quarantine.

No. Ventilation is air exchange between inside and outside. It dilutes the concentration of contaminants, and hence helps to control aerosol-based cross-infection risk of COVID-19.

No. One cannot rely solely on a strategy of dilution through building ventilation to reduce the risk of COVID-19 transmission to a low level.
