Investigating Viral Inoculation and Recovery from Medical Masks

Figure 1

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.
