Abstract. We found that several solidstate cuprous compounds, including cuprous oxide (Cu (2)O), sulfide (Cu (2)S), iodide (CuI), and chloride (CuCl), have highly efficient antiviral activities, whereas those of solidstate silver and cupric compounds are markedly lower. On a Cu (2)Oloaded glass substrate, for example, the infectious activity ...
