Background The COVID-19 pandemic and its associated morbidity, mortality, and economic disruption has reignited interest in simple protective and preventive measures. Aims The aim of this study was to assess the knowledge, attitudes, and practices (KAP) of hand hygiene in a sample of medical students in Ireland and members of the public to evaluate these within the context of the COVID-19 pandemic. We also explored any differences between the two groups. Methods A 35-question survey was formulated and circulated to potential participants comprising Irish medical students and members of the public. The data was analysed using Microsoft Excel with P-values being calculated using chi-squared goodness-of-fit analysis. Results There were 356 responses to the survey, categorised into medical students and general public populations. Incomplete surveys were removed leaving 303 responses. There was no statistical difference between the groups for attitudes and self-reported practices towards hand hygiene. Statistical differences were found between the two groups in terms of knowledge. Conclusions The study showed that medical students and the public had a good knowledge base and positive attitude in regards to hand hygiene. Both groups displayed consensus that the practices are essential, especially within the current pandemic context. However, larger studies, involving multiple universities and a larger portion of the public, may be useful to ascertain whether there is a true difference in the KAP between healthcare students and the general public.
