[Cases of pertussis among healthcare workers in a maternity ward: management of a health alert].

UNLABELLED
Pertussis is a highly contagious acute respiratory tract infection, with a poor prognosis in non-vaccinated new-borns.


OBJECTIVES
The authors had for aim to investigate an epidemic of 5 pertussis cases among health care workers (HCW) in our maternity ward with potential exposure of new-borns and to evaluate HCW compliance and experience gain.


METHODS
A retrospective study was made using a questionnaire with HCW on preventive measures taken (antibiotic prophylaxis with erythromycin and wearing a mask).


RESULTS
Two hundred and thirty-eight patients were warned of a potential pertussis contamination. No nosocomial case was detected among patients or their new borns. Ten proved or probable cases were identified among 101 HCW having answered (N=101/210, 48%). Sixty percent of HCW people followed the antibiotic treatment and 85% wore a mask among whom 46% adequately. Non-compliance factors were mainly related to adverse effects (41%), delayed information (41%), and false vaccine protection (22%). Crisis communication was felt as unsatisfactory for 72% of HCW and recommendations not adapted for 39% of the staff.


CONCLUSION
This survey points out the difficulty of managing a pertussis alert in a medical ward.
