Can people infected with COVID-19 spread the disease before appearing to be ill?

Yes. US health officials have indicated that the COVID-19 virus can indeed be spread by infected individuals prior to the onset of symptoms such as coughing, fever, and shortness of breath. National and international health organizations working to mitigate the spread of the virus are still collecting data on asymptomatic transmission (transmission by people who show no symptoms).
