China curbs optimism as coronavirus cases rise in South Korea
Chinese health officials sent out an optimistic message about progress against the coronavirus, the South Korean Prime Minister says the country has entered an emergency phase; Fox News correspondent Jonathan Serrie reports.
The novel coronavirus that's spread to dozens of countries across the world may be able to live on surfaces, namely metal, glass or plastic, for up to nine days — if it resembles some of its other human coronavirus-causing “cousins,” that is.
In an analysis of 22 studies on other human coronaviruses — such as Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS), and endemic human coronaviruses (HCoV) — researchers found the viruses can “persist on inanimate surfaces like metal, glass or plastic for up to nine days.” More specifically, the viruses can remain infectious on such materials between “two hours up to nine days,” according to the paper published in The Journal of Hospital Infection.

The researchers also found that temperatures of 30 or 40 degrees Celsius (about 86 degrees Fahrenheit and 104 degrees Fahrenheit, respectively) “reduced the duration of persistence” of some of the viruses.
What’s more, they also found that many of the coronaviruses studied could be “efficiently inactivated” by common household cleaners. Disinfectants “with 62-71 percent ethanol, 0.5 percent hydrogen peroxide or 0.1 percent sodium hypochlorite” — bleach — was able to inactive the viruses within a minute, according to the study.
“We expect a similar effect against the SARS-CoV-2,” or the novel coronavirus, researchers said.
The Centers for Disease Control and Prevention (CDC) on its website warns human coronaviruses most commonly spread through the air when an infected person coughs or sneezes, close contact with an infected person (shaking hands, for example), but also by touching an object or surface that has been exposed to the virus, then touching your mouth, nose, or eyes with dirty hands.

Transmission via inanimate objects sparked concerns that imported goods from China could pose a health risk. But an infectious disease expert previously told Fox News it’s unlikely the virus will survive the journey from China to your front door.
“The virus on materials they ordered would not survive such a trip. Outside the body, we believe this virus only survives on [an] object minutes to an hour or so, not the days it takes your goods to travel the globe,” Patricia A. Stinchfield, vice president of the National Foundation for Infectious Diseases (NFID), told Fox News at the time. “As always after handling things, wash your hands before touching your eyes, nose or mouth.”
