As the new coronavirus spreads quickly around the world, U.S. health officials say they are "aggressively" assessing how long it can survive on surfaces to better understand the risk of transmission.

Based on what is known about similar coronaviruses, disease experts say the new outbreak of the virus, named COVID-19, is mainly spread from person to person through coughing or sneezing. Contact with fecal matter from an infected person may also transmit the virus.

The U.S. Centers for Disease Control and Prevention says it may be possible for a person to become infected by touching a surface or object that has the virus on it and then touching their own mouth, nose or eyes.
