In this study, nearly 80% of Staphylococcus aureus placed on US heads in gel survived for 1 hour, with survival of 3 days possible in other types of organic matter” Spratt et al (2019).

Abstract:

Therapeutic ultrasound (US) is commonly used in the rehabilitation of soft tissue injuries including wounds. US heads and coupling gel come into direct contact with patient skin, increasing the risk for health care-associated infections owing to cross contamination. In this study, nearly 80% of Staphylococcus aureus placed on US heads in gel survived for 1 hour, with survival of 3 days possible in other types of organic matter.
