[Prevention of whooping-cough cross transmission in maternity hospital].

INTRODUCTION: Reports of pertussis have been increasing since 2008 in North of France. A large part of reported cases involved healthcare workers (HCWs) in nurseries and maternity hospitals. The objective of this study was to determine HCWs' knowledge regarding pertussis and its cross-transmission in the maternity hospitals in North of France. METHODS: This study was conducted in the 38 maternity hospitals set in North of France. Head midwives and nurses, infection control teams and occupational health practitioners were asked through a self-administered questionnaire survey to assess there knowledge regarding pertussis: vaccination, diagnosis, cross-transmission control. RESULTS: 36 on the 38 maternity hospitals' staffs returned the survey. Most of the respondents viewed pertussis as a serious and highly transmissible illness but 30% of them considered it a paediatric illness. Only a minority of the participants knew the last recommendations for pertussis vaccination in HCWs (37%) and in adults (16%). Only a few maternity hospitals staffs have set a formal organization to prevent and control pertussis cross-transmission. CONCLUSION: Awareness about pertussis vaccination and its cross-transmission control needs to be increased among maternity hospital staffs. A close liaison between HCWs, occupational health, infection control teams and biologists is necessary to prepare operational procedures to control pertussis cross transmission.
