A systematic review and meta-analysis (n=78 studies) found that laboratories had the highest proportion of surfaces test positive for SARS-CoV-2 while household surfaces had the lowest. In assessing surface stability using infectivity, half-life of SARS-CoV-2 on stainless steel, plastic, and nitrile was 2.3-17.9 hours, and decreased at higher temperature and humidity. Disinfection studies with SARS-CoV-2 or surrogate viruses indicated that sunlight, ultraviolet light, ethanol, hydrogen peroxide, and hypochlorite can attain 99.9% reduction in infectivity.
