Boil-water advisories (BWAs) are one of the several methods to prevent the spread of infectious diseases through contaminated water. However, for BWAs to be effective, consumers need to be aware of, understand and comply with the advisories. Although BWAs are a widely used preventive public health measure, compliance with BWAs is rarely examined. In Norway, only one previous study on compliance with BWAs has been conducted. Therefore, we conducted a cross-sectional study to estimate consumers’ perception of and compliance with a BWA following a contamination incident at an elevated reservoir in Konnerud (population 10,314), Norway. In total, 2,451 of the 9,312 (26.3%) invited residents responded to the questionnaire. Among the respondents, 97.6% remembered receiving the BWA, of whom 94.6% complied with the advice. Effective compliance with the BWA was thus 92.3%. Only 130 (5.4%) respondents did not comply with the BWA. The main reason for non-compliance was perceived low or no risk of getting sick from the water (34.2%). Our study revealed high awareness of and compliance with the BWA, but the people who did not comply maintained several misconceptions about waterborne infections and transmission. The findings can be used by local health authorities to improve future BWAs.

沸水咨询（BWAs）是防止传染病通过污染水传播的几种方法之一。但是，为了使BWA有效，消费者需要了解，理解并遵守这些建议。尽管BWA是广泛使用的预防性公共卫生措施，但很少检查BWA的遵守情况。在挪威，以前仅进行过一项关于遵守BWA的研究。因此，我们进行了一项横断面研究，以估计消费者在挪威Konnerud高水库（人口10,314人）发生污染事件后对BWA的认识和遵守情况。在9,312位受邀居民中，共有2,451位回答了问卷。在受访者中，有97.6％的人记得收到了BWA，其中94.6％的人遵守了建议。因此，对BWA的有效遵守率为92.3％。只有130（5.4％）个受访者没有遵守BWA。人们认为不合规的主要原因是从水生病的风险低或没有患病的风险（34.2％）。我们的研究表明对BWA的高度了解和遵守，但不遵守BWA的人对水传播的感染和传播保持了一些误解。该发现可被当地卫生部门用于改善未来的BWA。
