Coronavirus symptoms: What are they and how do I protect myself?

Coronavirus has spread to 177 countries or territories, including the UK, and claimed more than 34,000 lives.
So, what is the disease, how does it spread and when are people most infectious?
How do I protect myself?
The best thing is regular and thorough hand washing, preferably with soap and water.
Coronavirus spreads when an infected person coughs small droplets - packed with the virus - into the air. These can be breathed in, or cause an infection if you touch a surface they have landed on, then your eyes, nose or mouth.
So, coughing and sneezing into tissues, not touching your face with unwashed hands, and avoiding close contact with infected people are important for limiting the spread.
