A bandage of the type used on acute wounds, minor wounds, burn wounds and irritations, includes a first layer for covering the wound site and an area around the wound site, with the first layer including a top surface and bottom surface; a second layer over the first layer bottom surface, for absorbing exudates from the wound site; the second layer including a poly(ethyleneoxide)-based compound and a chitosan-based compound. A third layer is situated over the second layer, the third layer being of a perforated film, and wherein, at least one antimicrobial agent is associated with the bandage in a position where the antimicrobial agent will come in contact with the wound site, and which is transferable from the bandage to the wound site, upon contact with the wound site.
