In December 2008, three hospitalized cases of suspected @entity281 were notified by @entity1576 clinicians from a local hospital to the Regional Epidemiology Unit of Pays de la Loire, France. They all had attended a bird fair. A retrospective cohort study was conducted among exhibitors and organizers to identify potential risk factors in relation to this fair. Environmental and veterinary investigations were implemented to trace potential sources of @entity281 . We identified two confirmed, two probable and 44 possible cases among @entity1 . The attack rate in exhibitors and organizers was 38% (33/86). The median incubation period was 11 days (range 6-22 days). Individuals located in two particular sectors of the showroom were found to be at double the risk of developing @entity4440 (relative rate 2  1, 95% confidence interval 1  03-4  18) than those in other sectors. Pooled faecal samples of birds belonging to a possible case exhibitor tested positive for Chlamydiaceae by PCR. Ventilation conditions in the showroom were inadequate. This investigation allowed the formulation of recommendations to prevent @entity4440 in bird exhibitions which are held weekly in France.
