Hospital differ from conventional buildings in terms of ventilation needs. Exhaled infectious droplets or droplet nuclei of an infected patient need to be removed in general wards, waiting areas and isolation rooms to minimize transmission to health-care workers, other patients and visitors. In most health-care environments, harmful microorganisms and infectious aerosols may exist in relatively high concentration. They are particularly harmful to patients due to reduced immunity, and to those with open wounds.
