Because COVID-19 is a new virus, we are constantly learning more about what it is and how we can reduce its spread.
Below, we answer common questions about the virus:What is COVID-19 ("Coronavirus")?
The 2019 Novel Coronavirus (COVID-19) is a new illness that was first identified in Wuhan, China, in December 2019, with patients reporting cases of fever and acute respiratory illness. Since that time, other countries, including the U.S., have seen cases of the illness.How is the virus transmitted?
Coronaviruses are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as MERS and SARS. Many of the early patients in the pneumonia outbreak caused by COVID-19 in Wuhan, China had some link to large seafood and live animal market, suggesting animal-to-person spread. However, the person-to-person spread is now occurring.Person-to-person spread is believed to occur via respiratory droplets produced when an infected person coughs or sneezes.

These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. It may be possible for a person to get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose or possibly their eyes, but this is not thought to be the main way the virus spreads.
There is much more to learn about the transmissibility, severity, and other features associated with COVID-19 and investigations are ongoing. The latest situation summary updates are available on the CDC’s webpage Coronavirus Disease 2019.
