Paramedics with fire retardant clothing were spotted entering a house in central Liverpool.
The two doctors in white overalls and respiratory masks were seen walking in a terraced house in Falkner Square at 20.30 on Wednesday.
Security officer Keith Braithwaite, 58, was traveling down the road with his friend Tracey Williams, 51, when he saw paramedics and an ambulance.
Capturing the moment, Keith said he worried as soon as he saw doctors as fears around the world continue to grow over the spread of Coronavirus.
Keith said: “At first I had no idea what was going on and I thought it could be a crime scene.
“But there was no police and only that ambulance.
“As soon as I saw the suits I thought that the virus could have been immediately.
“It is worrying that it may be in Liverpool, close to home.
“It’s a concern.”
Keith added that the doctors in suits have entered only one house on the street.
The North West ambulance service said it could not comment on the accident.
The Department of Health has been contacted by ECHO for comment.

Professor Chris Whitty, Chief Medical Officer, said Thursday that there could be a “social cost” if the virus intensified, including school closings for more than two months.
He said at the Nuffield Trust summit: “One of the things that is really clear with this virus, much more than flu, is that everything we do will have to be done for a long period of time, probably more than two months.”
