The need to sanitise surfaces has always been important within both clinical and non-clinical settings, whilst surface disinfection compliance might be low. Unfortunately, COVID 19 has increased the urgency of need in order to minimise transmission of the virus. Some studies have indicated that the SARS-CoV-2 virus survives on stainless steel surfaces for as long as 3-7 days. On high-touch areas such as doors, virus transmission becomes an increased risk.

Leg ulcers (a long-lasting sore resulting from a break in the skin) represent a significant source of morbidity with many adverse physical, social and psychological consequences. With appropriate treatment, some ulcers heal successfully with a few weeks, however many persist for months and even years. Such lengthy treatment periods have led to the annual cost of wound treatment in the UK being estimated at £5.6 billion (Guest et.al. BMJ 2020).
