This nationwide surveillance involves a network of approximately 100 pediatric clinics that report all probable and confirmed HFMD cases. Following the COVID-19 pandemic, infectious disease surveillance systems must be evaluated to ensure the effective use of limited public health resources.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study aimed to evaluate the HFMD sentinel surveillance system in South Korea from 2017 to 2022, focusing on the transition period after the COVID-19 pandemic.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n We retrospectively reviewed the HFMD sentinel surveillance system from the Korea Disease Control and Prevention Agency using systematic guidelines for public health surveillance system evaluation developed by the US Centers for Disease Control and Prevention. We assessed the system\u2019s overall performance in 5 main factors: timeliness, stability, completeness, sensitivity, and representativeness (ie, the age and geographic distribution of sentinels). We rated these factors as weak, moderate, or good.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Our study showed that the completeness, sensitivity, and age representativeness of the HFMD surveillance performance were temporarily reduced to moderate levels from 2020 to 2021 and recovered in 2022, while the timeliness and geographic representativeness were maintained at a good level throughout the study period. The stability of the surveillance was moderate from 2017 to 2021 and weak in 2022.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n This is the first study to evaluate the HFMD surveillance system after the acute phase of the COVID-19 pandemic. We identified a temporarily reduced level of performance (ie, completeness, sensitivity, and age-specific representativeness) during the acute phase of the pandemic and good performance in 2022. Surveillance system evaluation and maintenance during public health emergencies will provide robust and reliable data to support public health policy development. Regular staff training programs and reducing staff turnover will improve HFMD surveillance system stability.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/59446","type":"journal-article","created":{"date-parts":[[2024,7,24]],"date-time":"2024-07-24T06:19:48Z","timestamp":1721801988000},"page":"e59446-e59446","source":"Crossref","is-referenced-by-count":17,"title":["The Hand, Foot, and Mouth Disease Sentinel Surveillance System in South Korea: Retrospective Evaluation Study"],"prefix":"10.2196","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1798-5315","authenticated-orcid":false,"given":"Bryan Inho","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8231-9776","authenticated-orcid":false,"given":"Chiara","family":"Achangwa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7727-2555","authenticated-orcid":false,"given":"Seonghui","family":"Cho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1065-3240","authenticated-orcid":false,"given":"Jisoo","family":"Ahn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2361-8666","authenticated-orcid":false,"given":"Jisu","family":"Won","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-6023-9186","authenticated-orcid":false,"given":"Hyunkyung","family":"Do","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1942-6666","authenticated-orcid":false,"given":"Dayeong","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0380-8312","authenticated-orcid":false,"given":"Bohye","family":"Yoon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0783-8758","authenticated-orcid":false,"given":"Joohee","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8915-8167","authenticated-orcid":false,"given":"Sukhyun","family":"Ryu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2024,7,23]]},"reference":[{"issue":"14","key":"R1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMicm0910628","article-title":"Images in clinical medicine. hand, foot, and mouth disease","volume":"362","author":"Goksugur","journal-title":"N Engl J Med"},{"issue":"1","key":"R2","doi-asserted-by":"publisher","DOI":"10.1136\/bmjgh-2017-000442","article-title":"Severity and burden of hand, foot and mouth disease in Asia: a modelling study","volume":"3","author":"Koh","journal-title":"BMJ Glob Health"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.1017\/S0950268819002279","article-title":"Risk factors for death from hand-foot-mouth disease: a meta-analysis","volume":"148","author":"Ni","journal-title":"Epidemiol Infect"},{"issue":"3","key":"R4","doi-asserted-by":"publisher","first-page":"112","DOI":"10.24171\/j.phrp.2018.9.3.05","article-title":"Estimating the incidence of cases and deaths resulting from hand, foot and mouth disease and its related socioeconomic disease burden in Republic of Korea (2010 - 2014)","volume":"9","author":"Seo","journal-title":"Osong Public Health Res Perspect"},{"issue":"6","key":"R5","doi-asserted-by":"publisher","first-page":"859","DOI":"10.1016\/j.jiph.2023.03.029","article-title":"Association of public health and social measures on the hand-foot-mouth epidemic in South Korea","volume":"16","author":"Ryu","journal-title":"J Infect Public Health"},{"key":"R6","unstructured":"Ministry for Health, Welfare and Family AffairsKorea Centers for Disease Control & Prevention.
