The Journal of Hospital Infection: Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents
The New Coronavirus Can Live On Surfaces For 2-3 Days — Here’s How To Clean Them
COVID19 doesn’t remain active for as long at temperatures higher than 86 degrees Fahrenheit (30 degrees Celsius). The authors also found that the coronaviru can be effectively wiped away by household disinfectants.
For example, disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can “efficiently” inactivate coronaviruses within a minute, according to the study. “We expect a similar effect against the 2019-nCoV,” the researchers wrote, referring to the new coronavirus. But even though the new coronavirus is a similar strain to the SARS coronavirus, it’s not clear if it will behave the same.
Diluted household bleach solutions, alcohol solutions containing at least 70% alcohol and most EPA-registered common household disinfectants should be effective at disinfecting surfaces against the coronavirus, according to the CDC. The bleach solution can be prepared by mixing 5 tablespoons (one-third cup) of bleach per gallon of water or 4 teaspoons of bleach per quart of water, the CDC wrote in a set of recommendations.
