Abstract: | ObjectivesPertussis surveillance in the French general population was stopped in 1986. Pertussis was added to the list of illnesses surveyed by the military epidemiological surveillance network ecause of outbreaks having occurred among French servicepersons and in military high schools. This study had for aim to report the results of the first year of surveillance.DesignPertussis declaration criteria were those recommended in 2006 by the French council for public hygiene. The data concerning active military servicepersons was collected by physicians of all military medical units. An anonymous declaration form was used for data collection.ResultsIn 2007, 66 cases of pertussis were reported in the military forces, 10 of which were excluded after a negative biological test. The classification of the 56 included cases was: 46% biologically confirmed cases, 20% clinically confirmed cases, 14% suspected cases, and 6% epidemiologically confirmed cases. The incidence density rate was 16.3 cases for 100,000 servicepersons-years. Age under 20 was associated with a 4.6 fold higher risk to develop pertussis.ConclusionsThe high incidence rate observed in individuals under 20 years of age could reflect a shift of pertussis reservoir to young adults, as observed in industrialized countries after generalization of vaccination programs. However, several years of surveillance will be needed to confirm this hypothesis. Meanwhile, the military epidemiological network could constitute an important surveillance marker of pertussis among adults in France. |
