HOUSTON — Anytime a fast-spreading deadly illness makes headlines around the world, people get nervous. 

But when it comes to a new type of human coronavirus that originated in Wuhan, China, your chances of becoming seriously ill are very slim, at this point. 

Since it originated at a Wuhan seafood market in China, thousands of people there have become ill and hundreds have died. 

As of Feb. 3, there are fewer than a dozen cases in the U.S. and no deaths.

Here are eleven fast facts about coronaviruses from the Centers for Disease Control.

1. Scientists know of seven different coronaviruses that can infect people and make them sick, including the new one from China.

2. Most people get infected with at least one common human coronavirus at some point in their lives.

7. SARS (severe acute respiratory syndrome) was another deadly coronavirus. It was first reported in Asia in 2003. It spread to more than two dozen countries in North America, South America, Europe and Asia, but was contained by 2004.

8. Human coronaviruses are usually spread through:

  • The air by coughing or sneezing
  • Close personal contact, such as touching or shaking hands
