While the new coronavirus ravages much of China and world leaders rush to close their borders to protect citizens from the outbreak, the flu has quietly killed 10,000 in the U.S. so far this influenza season.

At least 19 million people have come down with the flu in the U.S. with 180,000 ending up in the hospital, according to the Centers for Disease Control and Prevention. The flu season, which started in September and can run until May, is currently at its peak and poses a greater health threat to the U.S. than the new coronavirus, physicians say. The new virus, which first emerged in Wuhan, China, on Dec. 31, has sickened roughly 17,400 and killed 362 people mostly in that country as of Monday morning.

"In the U.S., it's really a fear based on media and this being something new," Dr. Jennifer Lighter, hospital epidemiologist at NYU Langone Health, said of the new coronavirus. "When in reality, people can take measures to protect themselves against the flu, which is here and prevalent and has already killed 10,000 people."

The coronavirus outbreak, however, is proving to be more deadly than the flu. It has killed roughly 2% of the people who have contracted it so far, according to world health officials. That compares with a mortality rate of 0.095% for the flu in the U.S., according to CDC estimates for the 2019-2020 flu season. The CDC estimates that 21 million people will eventually get the flu this season.
