Airborne infection in a fully air-conditioned hospital. IV. Airborne dispersal of Staphylococcus aureus and its nasal acquisition by patients.

摘要: Studies in a newly built hospital furnished with complete air conditioning where most of the patients are nursed 6-bed rooms showed that transfer from one patient room to another was very small, especially when there substantial flow consistent direction between and corridor, direct airborne particles even less. There was, however, no evidence any reduction rates nasal acquisition Staphylococcus aureus compared those be found naturally ventilated hospitals. The numbers Staph. given appeared have originated carriers other were many times greater than could accounted for by transfer. Although not detected, detailed study this excess genuine. It seems probable on basis investigations elsewhere occurs indirectly, through dispersal clothing nursing medical staff into strains which their outer clothes become contaminated while dealing patients. Reduction micro-organisms another, whether ventilation or means, can only clinical advantage if routes is, made, less route.
