Abstract
A method of treating a body fluid which is to be infused so as to inactivate any enveloped viruses in said fluid comprises mixing the body fluid with an effective amount of a photosensitizing agent which will bind to the viruses and/or virus infected cells and photosensitize them, and then exposing the resulting mixture to visible light to excite and inactivate the viruses. An apparatus for use in the method includes at least one container which contains an effective amount of the photosensitizing agent and which has at least one wall which is permeable to visible light. A number of photosensitizing agents which can be used in the method also are disclosed.
