Provisional data, 2018 These slides present provisional data on STIs notified to HPSC during 2018, via the Computerised Infectious Disease Reporting system (CIDR). STI data were extracted from CIDR on 20th March, 2019, and were correct at the time of publication. Data may change following validation, and as more enhanced forms are received from clinicans. Following validation of 2018 data, a more detailed report on the epidemiology of STIs for 2018 will be produced and this will made available at http://www.hpsc.ie/a-z/hivstis/sexuallytransmittedinfections/publications/stireports/

Provisional data, 2018 Aggregate data on ano-genital warts and non-specific urethritis are notified to HPSC on a bi-annual basis from Departments of Public Health and are reported separately.

Preventing STIs: Safer sex Get tested regularly. Information on free sexual health services in Ireland is available at: https://www.sexualwellbeing.ie/ http://man2man.ie/ (resource for gay and bisexual men)   Use condoms for vaginal, oral and anal sex Reduce the number of partners and overlapping partners. The more partners you have, the greater your chance of coming into contact with an infected person
