Abstract

The SARS-CoV-2 pandemic from 2019 onwards has significantly increased the usage of surgical style medical masks, both in healthcare and public settings. It is important to study the contamination of and viral transfer from such masks. However, accepted standard test methods such as ISO 18184 have prescribed inoculation methods which may not be fully representative of the type of viral insult experienced in the clinic or community. In addition to studying a conventional mask, the performance of a mask featuring an antimicrobial photosensitiser was also studied.

Viral recovery from standard (“control”) type IIR mask vs. photosensitiser-treated antiviral (AV) type IIR mask at stated times. The experiments compared are (a) standard ISO 18184 protocol, (b) viral transfer test via medical examination glove, (c) repeat inoculation with virus every 2 h for 8 h duration, and (d) aerosol inoculation via MAD device, over 4 h.
