– Could there be other symptoms?

The WHO says other symptoms can include shortness of breath, aches and pains, and a sore throat.

Some people have also reported a loss of taste and/or smell, as well as abdominal pains.

– When do symptoms begin to show and can they get worse?

Chief medical officer Professor Chris Whitty said that it takes about five days from getting Covid-19 for symptoms to show, and then up to a week to recover.

Those who get more seriously ill tend to do so after about five or six days of having the illness, he added.

– Can I get Covid-19 and not experience any symptoms?

According to the WHO, some people become infected but do not develop any symptoms and do not feel unwell.

– Who is most at risk?

Those with an underlying medical condition and people over the age of 60 have a higher risk of developing severe symptoms.

The WHO says that around one out of every six people who gets Covid-19 becomes seriously ill and develops difficulty breathing.
