This study explored the role of circuit parties on the incidence of gonorrhea among men who have sex with men (MSM) in Barcelona (Spain). Specifically, it aimed to detect cyclic peaks in the number of reported diagnoses of gonorrhea after gay circuit parties. We analyzed monthly cases of gonorrhea reported from January 2007 through December 2016 after the main annual gay circuit parties in Barcelona. We used the integer autoregressive model for time series with discrete values. The performance of the model was tested in heterosexual men and women, in whom the circuit parties could be expected to have no impact. A sensitivity analysis was conducted, changing post-event diagnosis windows to 1 week later/1 week before. In the study period, a total of 4182 of gonorrhea cases were detected, of which 74.8% (n = 2181) occurred in men who identified themselves as MSM. The average annual increase in gonorrhea cases reported among MSM was 32.57%. In an independent analysis of each gay circuit party, cases increased significantly in two of them. The results were also similar for same-sex practices among men only. On controlling for the increasing trend over the study period and the seasonal effect, an average of 1.16 gonorrhea cases in MSM (95% CI: 0.68, 1.64) were attributable to the celebration of one of the gay circuit parties considered. During the expected outbreak, an average of 13 gonorrhea cases were detected and between 5 and 13% were attributable to one of the circuit parties. In view of these findings, participants should consider seeking advice from their healthcare provider and practice safer sex using condoms to prevent sexually transmitted infections. Local public health services should be reinforced to ensure care for participants during and after gay circuit parties. More research is needed to design and implement preventive programs.
