Adequate ventilation can reduce the transmission of infection in health-care settings. Natural ventilation can be one of the effective environmental measures to reduce the risk of spread of infections in health care.

This guideline first defines ventilation and then natural ventilation. It explores the design requirements for natural ventilation in the context of infection control, describing the basic principles of design, construction, operation and maintenance for an effective natural ventilation system to control infection in health-care settings.
