Deficient hand washing facilities in public toilets in the time of the COVID-19 pandemic: A survey in one high-income country

Wilson, N.; Thomson, G.

Aims: To identify the extent of the provision of water and soap for hand washing in public toilets at the time of the COVID-19 pandemic. To also make comparisons with a pre-pandemic survey that included a sample of the same facilities. Methods: We collected data from 400 toilets that were open to the public; all those in three contiguous city council territories (228) and a further convenience sample of 172 around the rest of New Zealand. Comparisons were made with the data on the same facilities included in a 2012/2013 survey. Results: For all the toilets in this survey, 2.5% had no water for hand washing and 14.8% had no soap. There was COVID-19 related health messaging signage in 19.5% of toilets, with posters of the COVID-19 QR code used to facilitate contact tracing in 12.3%, and generic hand washing signage in 1.8%. The hand washing water had 'no touch' activation at 28.0% of toilets and at 18.5% for toilet bowl flushing. Toilet bowl lids were not present at 32.8%, and 2.3% of toilets had damage which would impair their functionality (eg, broken toilet seats). For the 128 sites that had also been examined in the previous survey, this new survey found significantly increased provision of soap (risk ratio = 1.47; 95%CI: 1.25 to 1.72), but no increased provision of water. Conclusions: Despite the serious threat of the COVID-19 pandemic, the majority of hand washing facilities in public toilets sampled required tap touching, and did not have health messaging. Nevertheless there has been some modest improvements in soap (but not water) provision since the previous survey eight years before.
