A BABY boy has become the youngest Brit with suspected coronavirus as his petrified dad revealed "we're in hell".

The eight-month-old tot and his mum have been put into quarantine in their own home after they both came into contact with an infected GP.

His dad, who asked not to be named, said his son had "all the coronavirus symptoms" and feared his four-year-old daughter has also caught the deadly bug in Worthing, West Sussex.

He told the Telegraph: "We're in hell, completely petrified. My ex-partner keeps breaking down in tears.

“We’re staying in the house and giving the kids Calpol and paracetamol, but nothing's working.

“My little boy has haemophilia and a lung condition, so he’s already poorly."

Meanwhile, public health officials are trying to track down a dozen patients treated by the GP last week over fears they may have caught the disease in Worthing Hospital.

It came hours after the first coronavirus case was confirmed in London today as the deadly bug spread to the capital.

The woman contracted the virus in China and flew to the UK where she tested positive at a hospital in central London yesterday afternoon.

It takes the number of cases in the UK to nine as officials scramble to find everyone she had been in contact with.

Professor Chris Whitty, Chief Medical Officer for England said: “One further patient in England has tested positive for novel coronavirus (COVID-19), bringing the total number of cases in the UK to nine.

“This virus was passed on in China and the patient has now been transferred to a specialist NHS centre at Guy’s and St Thomas’ in London.”

A total of 1,759 people have been tested for coronavirus in the UK, of which 1,750 were confirmed negative and now nine positive.

Five cases have been confirmed in Brighton, two cases in York, another in an undisclosed location and the ninth diagnosis in London.
