Modeling COVID-19 infection risks for a single hand-to-fomite scenario and potential risk reductions offered by surface disinfection

We used a quantitative microbial risk assessment approach to relate log(10) disinfection reductions of SARS-CoV-2 bioburden to COVID-19 infection risks. Under low viral bioburden, minimal log(10) reductions may be needed to reduce infection risks for a single hand-to-fomite touch to levels lower tha...

description We used a quantitative microbial risk assessment approach to relate log(10) disinfection reductions of SARS-CoV-2 bioburden to COVID-19 infection risks. Under low viral bioburden, minimal log(10) reductions may be needed to reduce infection risks for a single hand-to-fomite touch to levels lower than 1:1,000,000, as a risk comparison point. For higher viral bioburden conditions, log(10) reductions of more than 2 may be needed to achieve median infection risks of less than 1:1,000,000.
