What are coronavirus symptoms? How does it spread?

Symptoms of the virus that causes COVID-19 include fever, cough and shortness of breath, which may occur two days to two weeks after exposure. Most develop only mild symptoms, but some people develop more severe symptoms, including pneumonia, which can be fatal. The disease is especially dangerous to the elderly and others with weaker immune systems.

Coronavirus is spread through contact between people within six feet of each other, especially through coughing and sneezing that expels respiratory droplets that land in the mouths or noses of people nearby. The U.S. Centers for Disease Control and Prevention say it’s possible to catch the disease COVID-19 by touching something that has the virus on it, and then touching your own face, “but this is not thought to be the main way the virus spreads.”
