A British surgeon has tested positive for coronavirus — after operating on patients rather than self-isolating after returning from vacation in the hot-spot of Italy, according to reports.

The unnamed senior surgeon at Liverpool’s Aintree University Hospital returned from a family skiing trip on February 29 when Italy was already a known epicenter for the global spread, The Sun said.

“He came back and even though everyone knew if they traveled to [Italy] they should self-isolate, he didn’t and he went back to the hospital on the Monday,” a source told the UK paper.

He treated “scores” of patients and continued with surgery, where he treats a range of conditions from cancer to sinus disease, the paper said.

It is believed he attended a team meeting at the hospital last Wednesday alongside dozens of other surgeons — who also treated patients, unaware they potentially had been exposed, the report says.

He started feeling sick later that day, and tests for the virus later came back positive, the paper said. Other members of staff also started showing symptoms, with at least two already in self-quarantine, The Sun said.

“It’s very worrying for his patients and also for colleagues who have come into contact with him,” the source told the paper.

“He has a lot of expertise and is highly regarded and very experienced, so it is surprising he stepped foot in that hospital until he’d spent two weeks in self-quarantine.”

The case emerged as 456 people have been confirmed with the virus in the UK, and eight people have died.

“We can confirm that a member of staff based at Aintree University Hospital has tested positive for COVID-19 after recently returning from a holiday in Italy,” a spokesman for the hospital told the paper.

“The safety of our patients and staff is our top priority and we are working with Public Health England and NHS England to inform and advise everyone who may have come into contact with this individual.”
