Sexually transmitted infections during the COVID‐19 outbreak: comparison of patients referring to the service of sexually transmitted diseases during the sanitary emergency with those referring during the common practice

Abstract

To the Editor, Sexually transmitted infections (STIs) and diseases (STDs) affect millions of people every year worldwide.1 In Italy, data are provided by the Italian National Institute of Health (INIH) and reported to the European Centre for Disease Prevention and Control (ECDC).2, 3 In 1991 and 2009, the Italian sentinel surveillance system was established, consisting in 25 public centres (12 clinical, 13 laboratories) on the national field for diagnosis, treatment and data transmission to the INIH.4 The STDs service of Dermatology, Bologna belongs to it and is a free-access service (7.30–11 am) from Monday to Friday, with a patient flow of 50 patients/day. As consequence of the COVID-19 emergency, the Ministerial Decree limited the circulation in Italy from 9 March 2020 to 3 April 2020.3 Thus, after the lockdown, the number of accesses was reduced to a maximum of 30 accesses/day. We conducted a prospective observational study collecting age, sex, type of sexual relationship and diagnostic question for each patient referring to the service. Then, we compared data with those of the 4 weeks before the lockdown (20 February to 6 March 2020). We used the chi-square test for categorical variables (gender, diagnostic question and sexual orientation) and the t-test for continuous variables (age). After the lockdown, 200 patients attended the service, with an average flow of 10 patients/day. Patients' age ranged from 18 to 77 years. Concerning sexual orientation, 122 (61%) were heterosexual, 75 (37.5%) homosexual and 3 (1.5%) bisexual. Compared with the patients before the lockdown, they were more likely to be male (75.5% vs. 64.6, χ2 = 14.8, P < 0.001), MSM (37.5% vs. 28.8%, χ2 = 22.6, P < 0.001) and significantly older (35.4 vs. 33.1 years, t-test = 2.47, P = 0.018; Table 1). Before and after the lockdown patients from 15 to 49 years accounted for 88.6% and 85% but, among them, those from 15 to 24 years declined from 27.3 to 15.5% (χ2 = 12.3, P < 0.001) and, after the lockdown, the youngest patient was 18-year-old, while before he/she was 15-year-old. A total of 214 medical provisions were recorded after the lockdown: 13 patients required more than one healthcare service. The most common were prophylaxis (N = 28) and medical reports withdrawal (N = 52), accounting for 37.4%. Furthermore, consultations were for genital warts (N = 22, 10.3%), syphilis-related issues (N = 18, 8.4%), Neisseria gonorrhoeae infections (N = 17, 8%), Chlamydia thrachomatis (N = 13, 6.1%), non-Neisseria and non-Chlamydia urethritis (N = 9, 4.2%), Candida balano-posthites (N = 9, 4.2%), genital herpes (N = 9, 4.2%), molluscum contagiosum (N = 3, 1.4%), Candida vulvo-vaginitis (N = 2, 0.9%; Table 1). The remaining 33 medical provisions (15.4%) not included in the former categories, and defined as Other, encompass STIs-related and non-STIs-related issues, as therapeutic counselling and pathologies involving genital area (inflammatory diseases, or diagnostic workup). Before the lockdown, a total of 1081 medical provisions were delivered. The percentage of visits for prophylaxis declined after the lockdown, while visits for syphilis, gonococcal pharyngitis and inflammatory genital diseases increased significantly (Fig. 1). The percentage of patients requiring more than one provision increased from 2.1 to 6.5%, after the lockdown. Patients characteristics and medical provisions before and after the lockdown were consistent with the literature.3, 6, 7 However, the percentage of men who have sex with men (MSM) recorded remained higher than the national trends, (28.8% vs. <20%).2, 4 Moreover, the profile of patients and the type of medical provisions required changed. Whether this is due to a real decline of sex-related risk or if it is only a consequence of the fear of referring to hospitals, is unknown. Some Italian cardiologists, indeed, showed that during the lockdown the diagnostic delay of myocardial infarctions and cardio-vascular emergencies increased, leading to higher mortality/morbidity, especially when a timely intervention would have led to better outcomes.7 This is an open scenario and further information is required.
