Handvatten voor een effectieve aanpak ter voorkoming van klachten door zwemmersjeuk: Beslisbomen voor risicobeoordeling en maatregelen ter preventie van klachten bij bezoekers van zwemwaterlocaties

Swimmer’s itch (cercarial dermatitis) is the most reported health complaint in Dutch recreational waters. To reduce nuisance for visitors, water managers and provinces would benefit from a better knowledge on the circumstances under which swimmers itch symptoms occur, and a better grip on suitable mitigating measures. This report elaborates on a previous inventory on the incidence of swimmer’s itch in the Netherlands and offers – based on additional field and statistical research – concrete tools to mitigate swimmers itch via two decision trees: one to perform a risk assessment and one to select the most fitting measure(s) given the local circumstances. For both decision trees, the report supplies user guidelines, as well as scientific support for the included selection criteria.
