Adequate personal protective equipment is critical for ensuring the safety of nurses, doctors, and other frontline workers during the COVID-19 pandemic. Unfortunately, personal protective equipment supply chains are stretched, with a notable shortage of N95 masks for healthcare workers. Recently, decontamination has emerged as a promising strategy for maintaining the supply of medical masks. Instead of treating masks as single-use items, decontaminated masks can be used repeatedly, potentially providing a substantial reduction in demand for new masks. Heat, volatilized hydrogen peroxide, and ultraviolet-C (UV-C) irradiation are all promising strategies for decontamination. I will discuss some of the promises and pitfalls of UV-C decontamination, and will describe my lab’s work in optimizing UV-C irradiation strategies.
