According to NHS guidelines, people must self-isolate for 14 days if you are alive or are in a bubble with someone who is showing symptoms.
The Times and Telegraph reported that Deputy Chief Medical Officer for England Professor Jonathan Van-Tam is expected to announce the change of mind, which says people with symptoms should self-isolate for at least seven days.
It comes amid fears from health officials of a “second peak” and an ongoing row over 14-day quarantine measures put in place for travelers returning from Spain.
Health bosses have warned of “very high” levels of concern over the possibility of a second peak in coronavirus cases.
Niall Dickson, chief executive of the NHS Confederation, said combining a spike in cases with “exhausted staff” as the NHS tries to rebuild services could prove “difficult”.
He told the All-Party Parliamentary Group (APPG) on the Coronavirus: “I would say that in terms of the second peak problem or something to come, the levels of concern among our members – the people who run the trusts of the NHS, which run primary care and at all levels in the systems – is very high.
“Winter and aggravating factors are really concerned, but also a peak earlier.”
The move also follows a diplomatic row over the requirement that travelers from Spain be quarantined for a period of 14 days upon arrival in the UK.
Speaking on his return to the UK on Wednesday after cutting short a family holiday in Spain, Transport Secretary Grant Shapps said he could not rule out more countries being added to the list of submitted countries government quarantine restrictions.
