Although Dutch DCCs are legally required to report unusually high numbers of infections to Public Health Services (PHS), underreporting is common. Our pilot study aims to enhance DCC surveillance using a simple paper-based syndromic tool and wastewater monitoring.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Large DCCs in the Dutch PHS-region Zuid-Holland Zuid were invited. During 16\u202fweeks in summer and winter, DCCs recorded weekly counts of children (0\u20134\u202fyears) and staff with respiratory, gastrointestinal and skin infections using tally sheets. Incidence rates\/100 persons\/week were calculated and compared between seasons (Wilcoxon signed-rank test; DCC-level). In parallel, feasibility of local wastewater surveillance was assessed in stand-alone DCCs through sewer map review, on-site inspection and dye testing to identify DCC-specific sampling points, with planned analysis for parvovirus B19, norovirus and respiratory syncytial virus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Twenty-six DCCs participated in summer and 23 in winter. DCCs reported 7 mandatory outbreak notifications in summer and 4 in winter. Tally sheets showed a higher incidence in winter than in summer (20.1 vs. 8.8\/100 persons\/week;\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001). Respiratory infections predominated in summer and winter. Ten DCCs were assessed for wastewater surveillance feasibility. Due to infrastructural constraints, no DCC was suitable and wastewater surveillance was not performed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In our pilot study, paper-based syndromic surveillance provided insights into infectious disease incidences in DCCs beyond mandatory notifications, but was perceived as burdensome, whereas wastewater surveillance proved infeasible. Future DCCs surveillance should prioritize low-burden, scalable systems independent of healthcare-seeking, testing and reporting behaviour.<\/jats:p>\n
