What is coronavirus?
The new coronavirus is a respiratory virus discovered in China that causes a disease called COVID-19, which stands for coronavirus disease 2019.
How does coronavirus spread?
Evidence suggests it is mainly transmitted through contact with respiratory droplets produced when an infected person coughs or sneezes. However, the Centers for Disease Control and Prevention has said as much as a quarter of infections are passed through what's known as asymptomatic transmission, by talking or breathing.
Infectious disease experts say it's unlikely it would be transmitted through food, cuts or toilet spray.
What are the symptoms of coronavirus?
NBC News medical correspondent Dr. John Torres explained that roughly half of people who have coronavirus show symptoms in about five days. By 12 days, nearly everyone infected will show symptoms.
