STIs in Ireland, 2017 Provisional data These slides present provisional data on STIs notified to HPSC during 2017 via CIDR. Following validation of data, more detailed reports on the epidemiology of STIs for 2017 will be produced. Aggregate data on ano-genital warts (AGW) and non-specific urethritis (NSU) are reported to HPSC on a bi-annual basis from Depts. of Public Health and are reported separately. HIV, hepatitis B and sexually transmitted enteric infections (STEI), such as shigellosis, are reported separately. http://www.hpsc.ie/CIDR/ http://www.hpsc.ie/a-z/hivstis/sexuallytransmittedinfections/publications/stireports/ http://www.hpsc.ie/a-z/hivstis/sexuallytransmittedinfections/ano-genitalwarts/ http://www.hpsc.ie/a-z/hivstis/sexuallytransmittedinfections/non-specificurethritis/ www.hpsc.ie
