[Evaluation and validation of controls of aerobiocontamination in the prevention of nosocomial invasive aspergillosis].

Further to an invasive epidemic pulmonary aspergillosis, occurred in an onco-hematologic pediatric unit, an emergency plan has been organised and prophylactic precautions has been taken. The authors have retrospectively analysed the results concerning the aerial contamination. The authors have evaluated the efficacy of these prophylactic precautions. Their good results allow them to validate cleaning, disinfection and surveillance protocols.
