Identify potential sources and risk factors responsible for an outbreak of psittacosis among individuals attending an indoor bird fair.
Conducted a retrospective cohort study among bird fair exhibitors and organizers to trace clinical infections and exposure locations.
Implemented environmental evaluations of showroom ventilation and veterinary investigations using PCR testing on pooled bird faecal samples to identify Chlamydiaceae.
Identified 2 confirmed, 2 probable, and 44 possible cases, yielding an attack rate of 38% (33/86) among exhibitors and organizers with a median incubation period of 11 days (range 6–22 days).
Individuals situated in two specific sectors of the showroom had double the risk of developing psittacosis compared to those in other sectors (relative rate 2.1, 95% CI 1.03–4.18).
Showroom ventilation was inadequate, and pooled bird faecal samples belonging to a possible case exhibitor tested positive for Chlamydiaceae by PCR.
