An antiviral smartphone cover with infection preventive function to prevent infection of pathogens such as virus, bacteria and the like. The antiviral smartphone cover is made of a non-woven fabric in which copper having an antiviral activity is incorporated, and capable of generating copper ions. The copper ions can inactivate any viruses settling on the surface of a smartphone. Preferably, the non-woven fabric is made of a polymeric material in which insoluble copper oxide fine particles are incorporated in fibers. The size of the copper oxide fine particles is preferably between 0.2 to 20.

A case for PDAs is disclosed. The case is particularly suitable for maintaining mobile telephones free of infectious agents. The case includes a barrier material defining a body configured to enclose a PDA, and at least one drawstring fastener, wherein: (a) the case is configured to convert between a relaxed configuration which facilitates transfer of the PDA into and out of the case, and a fitted configuration which conforms more closely to the PDA enclosed therein, (b) the at least one fastener is configured to reversibly retain the case in the fitted configuration, and (c) the barrier material is effective to prevent viruses and bacteria from penetrating therethrough.
