摘要:
An antiviral agent having been experimentally supported which contains a powder obtained by baking (calcining) dolomite and hydrating a part thereof. Thus, it is possible to provide an antiviral agent which is usable in masks, filters, etc. because of acting directly on viral particles, thus eliminating the infectious capacity of the virus and preventing the invasion of the virus into cells; and a mask and a filter with the use of the antiviral agent.
