Coronaviruses are a large family of enveloped viruses that originate in animals but are known to cause respiratory illness in humans. Other novel coronaviruses have included Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS-CoV).1
Because it is a new illness, we are not certain of all of the way 2019-nCoV spreads from person to person, but similar viruses spread by cough or sneeze droplets.
Other coronaviruses have been shown to survive outside the host for up to 3 hours on dry inanimate surfaces.2, 3
Recent research suggests that this coronavirus can remain infectious on surfaces from 24 hours to several days.4
Equipment used in the case of suspected 2019-nCoV should be either single-use and disposable or dedicated equipment. If equipment must be shared among patients, clean and disinfect between use for each patient. Routinely clean and disinfect surfaces.5
