This review of previously reported studies was published in March 2020, so provides a very current update on the persistence of (human and veterinary) coronaviruses (such as SARS-CoV-2) on surfaces and their inactivation with potential disinfection reagents.
The analysis of 22 studies revealed that human coronaviruses such as SARS-CoV, MERS-CoV or endemic human coronaviruses (HCoV) can persist on surfaces like metal, glass or plastic for up to 9 days.
However, these coronaviruses can be effectively inactivated using common disinfectants including:
- 62–71% ethanol for 1 minute
- 0.5% hydrogen peroxide for 1 minute
- 0.1% sodium hypochlorite within 1 minute
Other biocidal agents such as 0.05–0.2% benzalkonium chloride or 0.02% chlorhexidine digluconate were found to be less effective.
