Declarations
:
: In the Netherlands, research is required to undergo review by an accredited Medical Research Ethics Committee if it is subject to the Dutch Medical Research Involving Human Subjects Act (WMO). Retrospective research (that is carried out on existing patient material and/or existing patient files) is exempt from the WMO, according to the Dutch Central Committee on Research Involving Human Subjects (CCMO) [CitationRef removed]. All data presented in this paper, including information obtained from affected institutions, were retrospectively retrieved from regular infectious disease control activities and were de-identified. As such, our study does not fall under the scope of the WMO and therefore is exempt from medical ethical approval. No additional administrative permissions were required to use the data as it is owned by the South Limburg Public Health Service.
