Mass testing trial aims to halve quarantine time of contacts

Mass testing trial using pregnancy-style kits aims to HALVE quarantine time for contacts of Covid cases – or eliminate it altogether – ending needless isolation

  • Mass testing will be trialled on emergency workers in Liverpool next week
  • It will also be offered to contacts of Covid-19 cases isolating for seven days
  • The testing scheme could then be offered nationwide from next year 

Quarantine for contacts of Covid-19 cases could be halved or eliminated entirely under mass testing plans, it has been suggested.

Pregnancy-style testing kits, which give results in minutes, would be used under the plans to identify un-infected contacts and release them from two-week quarantine.

The mass testing scheme will be trialled on emergency workers in Liverpool next week, who will return to shifts if they test negative.

It will also be rolled out to contacts of Covid-19 cases in the city who have been isolating for at least seven days.

If successful, it could be rolled out across the UK – although this isn’t expected to get the green light until next year. 

Experts heralded the scheme as offering a way of ‘un-crippling society and parts of the economy that are important at this critical juncture’.

Boris Johnson is currently self-isolating for two weeks after having a mask-less meeting with an MP who later tested positive for coronavirus.

It follows mounting concerns that contacts of Covid-19 cases are not following the two-week quarantine requirements, with one survey in September suggesting barely 11 per cent are following the rules. 

Emergency workers and contacts of Covid-19 cases who have been isolating for more than seven days will be offered the lateral flow tests. It is the next stage of the mass testing scheme pilot (Pictured: A woman gets swabbed in Liverpool)

It comes after mounting concerns over the performance of Test and Trace. It failed to reach a record number of positive cases in the latest week for which data is available 

MORE COVID-19 RESTRICTIONS IN THE NEW YEAR, WARNS DEPUTY CHIEF OF NHS PROVIDERS

The deputy chief executive of NHS Providers has said she expects lockdown restrictions to be in place into the new year to get us through the ‘hump’ of winter.

Saffron Cordery told BBC Breakfast the NHS workforce was now ‘incredibly tired’ as they treat coronavirus patients as well as trying to keep regular services open.

She added that the main priority for hospital chiefs ‘is to look after their staff so they can look after patients effectively,’ adding ‘they are acutely aware of how tired their staff are’.

‘There’s this huge hope (of a vaccine) among staff and among the general public and this sense of “oh we can take our foot off the peddle now”,’ she said.

‘But actually we can’t, we need to hold on just a little while longer until all of the elements are in place.’

Ms Cordery said she expected the restrictions to remain in place into the new year to make sure we are through the ‘hump of winter-meets-coronavirus’.

Emergency workers in Liverpool will be tested daily for Covid-19 from Monday, as part of the pilot, and release those in quarantine early.

Lateral flow tests which provide rapid results will be handed out to them. 

The mass testing scheme will require the approval of England’s chief medical officer Chris Whitty before it can be offered to all contacts nationwide.

Professor Calum Semple, an expert in outbreak medicine and member of SAGE at the University of Liverpool, told The Times the plans would release key workers from quarantine. 

‘If we use lateral flow tests on a daily basis, we can completely avoid quarantine,’ he said.

‘If you take a fire truck with six people and the driver is Covid-positive, then five people sitting behind him have to go into quarantine for 14 days. That’s quite a crude, arbitrary 14 days.

‘So we can take the other five people and give them a new driver, and give the rest of them multipacks of lateral low tests to use each morning before the shift. And we can keep that fire truck on the road.’

The arbitrary two-week quarantine period is meant to stop anyone who has been exposed to the virus, and hence could be infected, from spreading it further.

It was first recommended on the basis that anyone infected with the virus could take up to two weeks to show symptoms.

But many studies have shown that most people who are infected tend to show symptoms up to five days after they were first infected. These include a high temperature, new continuous cough and loss of taste and smell.

It comes after repeated warnings that most people told to self-isolate by Test and Trace may not be following the rules.

A study published as a pre-print in September on medRxiv found, after surveying more than 40,000 people, less than 11 per cent were following the two-week quarantine period.

There has also been mounting concern over Test and Trace’s ability to stop the virus from spreading in the UK.

The latest figures from the Department of Health on the system’s performance, released on Thursday, showed it had failed to reach a record number of Covid-19 cases, after appearing to get slightly better last week. 

It missed 21,419 positive cases in the seven-day spell to November 11, the largest number since it was launched in the UK.

Of the 156,853 Covid-19 cases transferred to the system, 84.9 per cent – or 133,195 – were reached and asked to self-isolate. This is slightly below the previous week, when 85.6 per cent of all Covid-19 cases – or 121,407 – were reached. 

Of close contacts, those who had been near Covid-19 cases for more than 15 minutes before they tested positive for the virus, the system reached the same proportion – 60.5 per cent – as the previous week. 

But this meant they failed to get hold of almost 189,885 people who could be infected with the virus, leaving them to continue to circulate in the community and possibly spread the disease further. In the previous week they missed 190,835 of these individuals.

Test and Trace — which Boris Johnson promised would be ‘world-beating’ — has fallen short of its targets for weeks. It has been struggling to get through to many Covid-19 patients and their contacts since infections began to surge again in late September.

Its former Talk Talk executive boss Baroness Dido Harding has come under mounting pressure to quit over the system’s performance.
