Officers say he travelled to Milton Keynes and London, and possibly to Birmingham, between 1 and 7 October.
Mr Lloyd was exposed to the malarial virus during an appointment in London on 1 October.
A police spokesman said: "There have been a number of calls from the public and possible sightings following the national media attention to Matthew's disappearance however none are confirmed at this time."
His family have said his disappearance is out of character and it is not known why he has gone missing.
On Tuesday Mr Lloyd's mother, Doreen Holland, from Somerset, urged her son to seek medical attention if he became unwell, adding "we love you son".
As well as having connections with Oxford for the clinical trial, Mr Lloyd is known to have links with Cornwall and the Avon and Somerset area.
