All swab tests on travellers being quarantined in Milton Keynes have come back negative - meaning it is unlikely any have coronavirus.
Milton Keynes Hospitals said all of those staying at Kents Hill Park Hotel will have to undergo further tests - after six and 12 days - and will remain in quarantine.
The results mean they will now be slightly less restricted in the way they move around the hotel.
But the hospital stressed all infection-prevention measures currently in place would continue.
The travellers arrived on a flight from Wuhan - the Chinese city at the centre of the coronavirus outbreak - on Sunday.
They flew in to RAF Brize Norton and were driven to Milton Keynes where they will have to stay for a total of 14 days while they are closely monitored for symptoms.
Public Health England said there were 105 British nationals and 95 Europeans on the flight.
