Bioburden is also associated with biofouling, where microbes collect on the surface of a device or inside of fan cooled equipment. In healthcare settings, this increases the risk of Healthcare-associated infections (HAIs) or Hospital-acquired infections as pathogens can be spread through contact or through the air to new patients and hospital staff. Fan cooled system are generally avoided in critical care and operating rooms, thus relying on natural convection or liquid cooling to cool devices and equipment. These rooms are also required to maintain negative air pressure so that air may enter the room, but the air cannot exit into other rooms . HEPA filters are also used to collect airborne pathogens larger than 0.3 microns.

Fan cooled system are generally avoided in critical care and operating rooms, thus relying on natural convection or liquid cooling to cool devices and equipment. Clean rooms (surgical operating rooms, for example) are also required to maintain positive air pressure so that air may leave those rooms, but contaminated air cannot enter from adjacent spaces . HEPA filters are also used to collect airborne pathogens larger than 0.3 microns.
