Feb 4: O modeling group says it's “It is not clear whether outbreaks can be contained by isolating and tracking contracts. If a high proportion of asymptomatic cases are infectious, containment through these policies is unlikely. "

March 17: Vallance is questioned by a selected committee on South Korea's testing and tracking strategy. "I think that would be absolutely brilliant in January," he says. "In the beginning, this type of approach makes perfect sense."
He says: “England's Public Health has a capacity of about 4,000 people [tests] per day. This will clearly not be enough going forward ".
He adds that the priorities are “they are patients admitted to intensive care units; those with respiratory illnesses in the hospital, pneumonia in particular; isolated cluster outbreaks, to ensure that we can understand what is happening there; and GP surveillance systems to try to understand what is happening in the community ”.
Asked about the decision to stop testing in the community, he says that “this is what we had to do with the capacity we have. We need to use the tests in the right place at the moment. We simply do not have mass tests available to the population now ”.
March 18th: Boris Johnson announces a plan for perform 25,000 tests per day. The next day, he says the daily tests will go "from 5,000 a day to 10,000 to 25,000 and then go up to 250,000".

Yvonne Doyle, England's director of public health protection for health, told the health selection committee that the “ship had sailed” in contact tracking in mid-March: “it became clear to us that there was what I call alleys no exit from contacts in which you had one. In this case, you tried to find the contact, and that simply was not possible, because it gave us the indication that there was sustained community transmission ”.
She says the situation was different in South Korea – there were "groups of cases where the initial transmission was well understood, because they were in specific communities and, in fact, it was quite regional".
"They were using people's personal data, including their bank accounts, and people were willing to pass that information on to get in touch with the tracking. It was very personal information. We analyzed this, and SAGE analyzed it and thought it was not appropriate here, "she says.
She describes a plan “for 1 million tests, which people can do for themselves … they can do a blood test, send it back to the post and analyze it. This is an antibody test that tells you if you have had the disease.
