Social restrictions did not reduce Chlamydia trachomatis (CT) or Neisseria gonorrhoeae (NG) detections in Finland during the first 6 months of the pandemic.1 We explored the incidences of laboratory-confirmed CT, NG and Treponema pallidum (TP) findings from March 2020 to February 2022. Incidence rate ratio (IRR) was used in comparisons.
We included a total of 103 292 CT, 3384 NG and 1407 TP detections (online supplemental file 1). There was minimal monthly variation in CT incidence (figure 1). During the second pandemic year, NG detections were higher in both groups (IRR 1.1, CI 1.0 to 1.3; IRR 1.2, CI 1.1 to 1.4) especially in the late 2021 (figure 1). TP detections remained practically unchanged in the first pandemic year (IRR 0.9, CI 0.8 to 1.1) but were lower in the second year (IRR 0.8, CI 0.7 to 0.9; figure 1).
Social restrictions did not reduce nationwide STI detections during the first pandemic year but travelling restrictions may have reduced TP detections during the second pandemic year, which was unsurprising as over 50% of these originate abroad.2
