Sexually transmitted infection diagnoses and access to a sexual health service before and after the national lockdown for COVID-19 in Melbourne, Australia
Abstract Background We aimed to examine the impact of lockdown on sexually transmitted infection (STI) diagnoses and access to a public sexual health service in the COVID-19 pandemic in Melbourne, Australia. Methods The operating hours of Melbourne Sexual Health Centre (MSHC) remained the same during the lockdown. We examined the number of consultations and STI at MSHC between January and June 2020 and stratified the data into pre-lockdown (3-February to 22-March), lockdown (23-March to 10-May) and post-lockdown (11-May to 28-June) with seven weeks in each period. Incidence rate ratio (IRR) and its 95% confidence intervals (CI) were estimated using Poisson regression models. Results The total number of consultations dropped from 7,818 in pre-lockdown to 4,652 during lockdown (IRR=0.60;95%CI:0.57-0.62) but increased to 5,347 in the post-lockdown period (IRR=1.15;95%CI:1.11-1.20). There was a 68% reduction in asymptomatic screening during lockdown (IRR=0.32; 95%CI:0.30-0.35) but it gradually increased in the post-lockdown period (IRR=1.59;95%CI:1.46-1.74). STI with milder symptoms showed a marked reduction, including non-gonococcal urethritis (IRR=0.60;95%CI:0.51-0.72), and candidiasis (IRR=0.61;95%CI:0.49-0.76) during lockdown compared with pre-lockdown. STI with more marked symptoms did not change significantly, including pelvic inflammatory disease (IRR=0.95;95%CI:0.61-1.47) and infectious syphilis (IRR=1.14;95%CI:0.73-1.77). There was no significant change in STI diagnoses in post-lockdown compared to lockdown. Conclusions The public appeared to be prioritising their attendance for sexual health services based on the urgency of their clinical conditions. This suggests that the effectiveness of clinical services in detecting, treating and preventing onward transmission of important symptomatic conditions is being mainly preserved despite large falls in absolute numbers of attendees.
