Abstract: Disclosed are efficient anti-viral compositions for application to surfaces, or within bulk materials, in order to effectively prevent the spread of the SARS-CoV-2 virus and other viruses or microbes. The disclosed silver-containing composition is particularly effective for its anti-viral properties due to a controlled release of silver ions over time. Some variations provide a disinfectant composition comprising: a silver-containing compound; a polymer; a reducing agent; and optionally, a wetting agent. Certain embodiments provide a disinfectant composition comprising: silver nitrate; a polymer; a reducing agent; optionally, a wetting agent; optionally, a binding agent; and water as solvent. The disinfectant composition may be in solution, gel, spray, foam, dry, or other form, for application to a substrate surface or impregnation into an object.
