The novel coronavirus has infected tens of thousands of people around the world since the outbreak first began in China in late 2019. The virus has now been reported on every continent except Antarctica.

Concerns about the virus have also spread across the world. We asked you for your questions about coronavirus. Here’s some of the ones that have been asked the most:

What are the symptoms of coronavirus?

The novel coronavirus, a cousin of the severe acute respiratory syndrome (SARS) virus, has symptoms that include a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days.

For those with a weakened immune system, the elderly and the very young, there’s a chance the virus could cause a lower, and much more serious, respiratory tract illness like pneumonia or bronchitis.

How is it treated?

There is no specific treatment, but research is underway.
