How long can the new coronavirus survive on the surface of an object?

BEIJING, Feb. 20 (Xinhua) — The central bank is deeply cleaning and even disposing of some of its cash amid concerns that the new coronavirus could survive or even spread on the surface of the coin, according tomedia reports. But how long can this new coronavirus survive on the surface of an object? Simply put, we don’t know yet. But a new study suggests that if it is similar to SARS and MERS, the new coronavirus can survive for up to nine days on surfaces such as metal, glass or plastic.

How long can the new coronavirus survive on the surface of an object?

By contrast, influenza viruses can survive only 48 hours on the surface of an object.

In the new study, to learn more about how long the new coronavirus is in vitro, the researchers analyzed more than a dozen previous papers on other human coronaviruses other than the new coronavirus. It was found that the coronavirus could survive on the surface of an object for up to a week, but its activity would disappear once the temperature exceeded 30 degrees Celsius. The researchers also found that home disinfectants were effective in killing these coronaviruses.

For example, the study notes that disinfectants containing 62-71% ethanol, 0.5% hydrogen peroxide, or 0.1% sodium hypochlorite can “effectively” inactivate the coronavirus within a minute. “We hope that these disinfectants will have a similar effect on this new coronavirus,” the researchers wrote in the paper. However, although the new coronavirus is similar to SARS, it is not clear whether the two viruses behave exactly the same.

The study also notes that we also don’t know how often hands are contaminated when they come into contact with patients or contaminated surfaces. WHO recommends using alcohol-based hand sanitizer and thoroughly rubbing your hands when washing your hands to disinfect your hands.

People may become infected with the virus after touching contaminated surfaces or objects, “and then touch their mouths, noses or eyes.” “But scientists believe this is not the main route of transmission of the virus, ” the CDC said. “

Instead, the CDC says the virus is most likely to be spread through close contact, as well as droplets from coughing and sneezing.

The study was published February 6 in the Journal of Hospital Infections.
