It has emerged that a Chinese national who is infected with coronavirus took an Uber to Lewisham hospital A&E on Sunday.
Two staff from the hospital are now in isolation at home after they came into contact with the woman.
Currently it is not known if coronavirus can survive on door handles, or grab poles on the Tube or busses, or if it can be spread by coughing or sneezing.
In a statement to the PA news agency, Ben Travis, chief executive of Lewisham and Greenwich NHS Trust said, “There has been a confirmed case of coronavirus from a patient who self-presented at the A&E department of University Hospital Lewisham on Sunday February 9.
“The test result was confirmed as positive on Wednesday February 12 and we have been in touch with all staff who came into contact with the patient. The patient went to St Thomas’ yesterday evening.
“Our colleagues in our emergency departments are following the latest advice and protocols from Public Health England. In this case, the patient self-presented at our A&E.
“As soon as the patient did this, the patient was given a mask and then escorted to be tested in the dedicated area we have assigned for coronavirus testing outside the A&E building – while awaiting the installation of a purpose-built ‘pod’.
“As further assessment was required, the patient was then taken to a dedicated isolation room in the emergency department.
“In line with our protocols, throughout their care, the patient was escorted and did not come into contact with other patients.
“The patient was later discharged and taken home by London Ambulance Service.
“All staff who had direct contact with the patient have been contacted, including two members of staff who are undergoing active surveillance at home for a 14-day period as a precautionary measure – following the advice of Public Health England.”
