5-day self-isolation criticized

The Health Secretary announced the rule change for England in the House of Commons saying “that around two-thirds of positive cases are no longer infectious by the end of day five”.

Story Highlights:

  • An expert has accused the government of “not following the science” after self-isolation for people with COVID was cut from seven to five days on Thursday.

  • The government has been under increased pressure from the private sector and the NHS recently to do something about the high numbers of people absent from their jobs due to being forced to self-isolate.

There have been calls throughout the week to cut the self-isolation period after the US reduced theirs to five days last week.

Some scientists have reacted with alarm at the news, Professor Lawrence Young, Virologist and Professor of Molecular Oncology, Warwick Medical School, University of Warwick, said: “This policy is certainly not following the science”

He said: “Reducing the self-isolation period to five days runs the risk of highly infectious people returning to work or school, particularly if people don’t use lateral flow tests as advised on day five and six.” He added: “A recent study from Japan of 21 hospitalised cases with omicron infection who had been vaccinated has shown that peak infectiousness occurs at three to six days after diagnosis or symptom onset but found that no infectious virus was detected after 10 days.

Prof Young said reducing the isolation period could only work with strict enforcement of lateral flow testing, but the current shortages of tests will make that harder. Lateral flow tests are key to the new plan. (PA)

The move to five-day isolation, which comes into effect on Monday, will double the number of people still infectious after coming out of quarantine, according to the government’s own analysis. He added: “It will also be important to stress that anyone ending isolation on day six should continue to be cautious – wear a face-covering in crowded or poorly ventilated spaces and limit contact with vulnerable people.”
