Experts believe the novel coronavirus, or COVID-19, is thought to be spread mainly from person-to-person, usually between people who are in close contact with each other - within about 6 feet.
Since the coronavirus and the flu are both respiratory diseases, that means the best way to protect yourself from both is by doing the same types of things.
ABC News' Chief Health and Medical Editor Dr. Jennifer Ashton says there are some practical things you can do that will make a difference.
Hand hygiene is crucial; that means washing with soap and water for at least 20 seconds after using the bathroom, sneezing or blowing your nose.
Avoid touching your face, cover your cough, and sneeze into the crook of your arm.
Try to limit hand-shakes and hugs.
Experts say it's possible that a person can get sick by touching an object that has the virus on it, then touching their mouth, nose or eyes.
So, clean surfaces you touch often - like desks, kitchen counters, your phone and your laptop.
As for face masks, the CDC says it does not recommend healthy people wear a facemask to protect themselves from respiratory diseases, including COVID-19.
But doctors say facemasks should be worn if you're sick and coughing or showing symptoms.
Avoid contact with people who are sick and if you're sick, stay home.
Dr. Ashton advises that if you have a fever, you're considered contagious for at least 24 hours, so you should stay home until you have not had a fever for at least 24 hours, without the use of an anti-fever medication.
If you feel sick with a fever, cough or have a hard time breathing, seek medical care right away.
