|Infectious diseases can spread from one person to another by aerosol droplets. The spread of Tuberculosis (TB), for example, occurs when an otherwise healthy individual inhales a sufficient number of tubercle bacilli that are expelled by a patient infected with pulmonary TB. Thus it spreads rapidly to the healthy persons. To avoid this hospitals provide special room to treat this patients.
Biologically Cleanroom is needed for control of micro organism in treatment Room, Operating Room, Operating Theatre, ICU/CCU, and Medicine Room.
