However, epidemiological information is limited. We aimed to describe <jats:italic>Campylobacter<\/jats:italic> epidemiology in Ireland and trends over time, to inform future surveillance and research. We reviewed data completeness and described notified cases of campylobacteriosis (2004\u20132016) by age, sex, geographical area, season and trends over time. We used negative binomial regression to estimate incidence rate ratios (IRR) and adjusted IRR (aIRR) by age group, sex, geographical area and season. We undertook interrupted time\u2010series analysis by age group and geographical area incorporating terms for trend and period (2004\u20132010 and 2011\u20132016). There were 27,034 cases of campylobacteriosis notified between 2004 and 2016. Data were &gt;99% complete for notification date, geographical area, sex and date of birth. Crude annual incidence ranged from 36.2 to 54.4 per 100,000 population. The incidence was higher in, males (aIRR 1.15, 95% confidence intervals (CI) 1.12\u20131.19), those aged &lt;5\u00a0years compared with the lowest incidence age group (45\u201364\u00a0years) (aIRR 4.65, 95% CI 4.43\u20134.88), other seasons compared with winter and all other areas compared with the north\u2010east area (aIRR range 1.22\u20131.71, <jats:italic>p<\/jats:italic>\u2010values &lt;.001). In 2011, we observed a stepped increase in annual crude incidence overall, in both sexes, all age groups and most geographical areas. This pattern was mirrored on time\u2010series analysis, with significant increases in trend\u2010adjusted incidences of 30%\u201345% (<jats:italic>p<\/jats:italic>\u2010values \u2264.008) detected for all age groups and 30%\u201366% (<jats:italic>p<\/jats:italic>\u2010values \u2264.012) for seven out of eight geographical areas after 2011. <jats:italic>Campylobacter<\/jats:italic> remains the most commonly notified bacterial cause of gastroenteritis in Ireland. With available information, we could not fully explain a stepped increase in incidence observed in 2011. The transition of regional laboratories from culture\u2010based to molecular\u2010based <jats:italic>Campylobacter<\/jats:italic> diagnostic methods was a possible contributor. However, further investigation is required to fully explain the identified changes.<\/jats:p>","DOI":"10.1111\/zph.12695","type":"journal-article","created":{"date-parts":[[2020,3,7]],"date-time":"2020-03-07T05:49:33Z","timestamp":1583560173000},"page":"362-369","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Epidemiology of Campylobacter infections in Ireland 2004\u20132016: What has changed?"],"prefix":"10.1111","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9350-6200","authenticated-orcid":false,"given":"Lois","family":"O'Connor","sequence":"first","affiliation":[{"name":"European Programme for Intervention Epidemiology Training (EPIET) European Centre for Disease Prevention and Control (ECDC) Stockholm Sweden"},{"name":"Health Protection Surveillance Centre Dublin Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"McKeown","sequence":"additional","affiliation":[{"name":"Health Protection Surveillance Centre Dublin Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alicia","family":"Barrasa","sequence":"additional","affiliation":[{"name":"European Programme for Intervention Epidemiology Training (EPIET) European Centre for Disease Prevention and Control (ECDC) Stockholm Sweden"},{"name":"Instituto de Salud Carlos III Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Garvey","sequence":"additional","affiliation":[{"name":"Health Protection Surveillance Centre Dublin Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,3,6]]},"reference":[{"key":"e_1_2_9_2_1","volume-title":"Population and Labour Force Projections 2016\u20132046","author":"Central Statistics Office"},{"issue":"7","key":"e_1_2_9_3_1","first-page":"19123","article-title":"Risk factors for sporadic Campylobacter infection: An all\u2010Ireland case\u2010control study","volume":"14","author":"Danis K.","year":"2009","journal-title":"Euro Surveillance"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.18553\/jmcp.2017.23.8.809"},{"key":"e_1_2_9_5_1","first-page":"e596","volume-title":"The European Union One Health 2018 Zoonoses Report","author":"European Centre for Disease Prevention and Control & European Food Safety Authority","year":"2019"},{"issue":"1","key":"e_1_2_9_6_1","first-page":"1496","article-title":"The Community Summary Report on trends and sources of zoonoses and zoonotic agents and food\u2010borne outbreaks in the European Union in 2008","volume":"8","author":"European Food Safety Authority","year":"2010","journal-title":"European Food Safety Authority Journal"},{"key":"e_1_2_9_7_1","volume-title":"Recommendations for a Practical Control Programme for Campylobacter in the Poultry Production and Slaughter Chain","author":"Food Safety Authority of Ireland","year":"2011"},{"key":"e_1_2_9_8_1","volume-title":"Report of the Campylobacter Stakeholder","author":"Food Safety Authority of Ireland Campylobacter Stakeholders Group","year":"2017"},{"issue":"1","key":"e_1_2_9_9_1","doi-asserted-by":"crossref","first-page":"124","DOI":"10.1093\/rheumatology\/keq242","article-title":"Anti\u2010TNF therapy is associated with an increased risk of serious infections in patients with rheumatoid arthritis especially in the first 6 months of treatment: Updated results from the British Society for Rheumatology Biologics Register with special emphasis on risks in the elderly","volume":"50","author":"Galloway J.
