I saw on tv where some five million residents have left Wuhan for other parts of China or the world. I doubt there have been so many carriers as that represents in the history of the world except perhaps for the Black Death. Imagine how many exposures would result from even a half million scattering out from the epicenter.
First off, what makes you think they are carriers and not people who aren’t infected and didn’t want to get infected? In other words, what percentage of the 5 million who fled Wuhan were you estimating had contracted the illness without symptoms? It is reasonable to believe some were carriers, but not really reasonable to believe that they all were.
Second, every year in the United States alone the CDC estimates that between 9 and 45 million people contract influenza. Depending on the year, it is estimated that 12,000 – 61,000 have died of influenza in the US every year since 2010.
Worldwide, the figure is estimated at 1 billion infections, 3 to 5 million severe cases, and 300,000 to 500,000 deaths every year. The highest estimates I have heard for likely infections with coronavirus 2019-nCoV, including asymptomatic people, is 100,000 so far. It will undoubtedly get worse before it gets better, but so far it is not the flu. (Severity of 2019-nCoV ranges all the way from barely noticeable to deadly.)
The Spanish influenza pandemic of 1918 caused illness in 500 million people–about 1/3 of people living at the time–and killed an estimated 20 to 50 million people, about 3% of the world’s population.
According to fairly recent estimates, between 291,000 and 646,000 people worldwide die from seasonal influenza-related respiratory illnesses
each year if
deaths due to pandemics are not counted.
If you’re taking precautions against influenza, that’s likely to be the same things needed to lower your risk of contracting 2019-nCoV. The good news is that although 2019-nCoV is spreading faster than the SARS corona virus of 2002, it is also believed to have a far lower fatality rate than SARS.
SARS killed 774 people between November 2002 and July 2003. More than 2,100 people have died from the new Wuhan coronavirus since December.

There are not yet any cases of person-to-person spread taking place within the United States. Still, it is definitely flu season, and observing hand-washing and other protocols to prevent the spread of influenza would also help to prevent the spread of 2019-nCoV, should it enter the US community.
