Downing Street has contradicted an education minister by saying that children who test positive for coronavirus in a lateral flow test can be cleared to go to school if they later test negative in the more reliable PCR test.
Children’s minister Vicky Ford sparked alarm among parents by saying that schools should not take the risk of having a child in the classroom after testing negative in a rapid-turnaround test carried out at home – even if they are later shown by a laboratory test not to have the virus.
But Boris Johnson’s official spokesman later insisted that the opposite was true, telling reporters that a pupil can come out of self-isolation and return to school if the lab test comes back negative.
He told a regular Westminster media briefing: “If a PCR test is negative following a positive lateral flow, children can go back to school.”
The spokesman said that the aim would be to get PCR tests out “as quickly as possible” after the positive lateral flow test performed at home.
Back-up PCR tests are not needed after rapid tests performed at school, because they are done “under supervision in a controlled environment”, he said.
The contradictory messages fuelled confusion on the day when schools across England began welcoming millions of children back in the first major step in easing the national lockdown after more than two months.
Upon returning, students in secondary schools and colleges will have to take three lateral flow tests onsite under supervision, before being asked to perform the rapid tests twice a week at home.
Questioned on the new testing system, Ms Ford told BBC Radio 4’s Today programme: “If they test positive then they shouldn’t be in school.
“The lateral flow test – as we heard yesterday from Public Health England – have got less than one in 1,000 chance of having a false positive. So if they test positive they should stay out of school.”
Presented with the situation of a child testing positive using a self-administered lateral flow device (LFD) test at home, who then received a negative result after using a laboratory test — known as a PCR test — Ms Ford suggested they would still have to complete their 10-day self-isolation period.
“The first priority is to make sure we keep the Covid out of the classrooms, with these regular tests,” she stressed.
“The chance of a lateral flow test giving a false positive are actually very low. There will obviously be discussions with the pupils and their families if they then have the negative test later.”
“The really important thing here is to make sure we can keep schools open and minimise the risk of having Covid in the classrooms and that is why people who’ve had the test that shows they have got Covid through the lateral flow test, we should not take the risk of having the child in the classroom.
Quizzed on whether a laboratory test could override the lateral flow test, the minister went on: “They should not take the risk. We all want to make sure that we can keep Covid out of the classrooms here.”
Shadow schools minister Wes Streeting criticised the Government for confused messaging.
“What hope is there for schools, parents and pupils when ministers in the Department For Education can’t get their basic facts right?” he asked.
“Is there a single day or a single announcement or a single initiative that Gavin Williamson’s bungling team have managed to get through unscathed? Worse than useless.”
