There is a growing evidence the SARS-CoV-2 survives well on various surfaces even up to several days (e.g., on plastic and stainless steel). However, it is not clear if the common practice of disinfection of surfaces is the optimal one, how effective it is, and if it can be improved. In many cases the drying of disinfection chemicals might leave behind stable thin liquid films and tiny microdroplets (termed microscopic surface wetness), invisible to the naked eye, which likely impacts viruses’ survival. In our lab we commonly study the survival of microorganisms on drying surfaces and in microscopic surface wetness. We recently showed that bacteria can survive in such microscopic wetness even for days. Yet, it is unknown how viruses like the SARS-CoV-2 can survive and remain stable on drying surfaces in particular after disinfection treatment. To study this question, we will test viral stability and survival on several surface types (e.g., plastic stainless steel, glass and cardboard), following suggested disinfectant treatments for SARS-CoV-2 and under various realistic environmental conditions. Then, we will work toward modifications of treatments or recommendations for post treatment steps (e.g. washing with specific agent), to improve common disinfection practices and reduce virus survival on surfaces.
