A school daily contact testing test funded by England’s Ministry of Health and Social Security and supported by the Ministry of Education and the National Bureau of Statistics, to investigate whether daily testing is as safe as sending close contacts home for quarantine and whether it will reduce absenteeism
.
The study showed that, on contact with the new crown pneumonia school students positive cases were detected daily and does not lead to a substantial increase in the number of new cases of pneumonia crown, and possibly reduce absenteeism associated with covid 39%

The researchers concluded that they have the confidence of 97.
5%, based on test participation rate, symptoms in the intervention group infection of any rate increase does not exceed 22% of the control group, if all people are eligible to participate in the daily testing do so , Which will not exceed 34%

Researchers randomly assigned 201 schools in England to a control group, where close contacts of positive cases were isolated for 10 days, or assigned to an intervention group, where close contacts came to the school and received 7 days in a supervised testing site Daily lateral flow testing

Participation of 5763 intervention group contacts in 27,973 potential isolation schools during the day
Participation of 5763 intervention group contacts in 27,973 potential isolation schools during the dayFrom April 19 to June 27, they found that in schools where contacts were quarantined, 59.
1 cases of symptomatic PCR-confirmed infections out of 100,000 students and staff per week (657 cases in 7,782,537 days); and In schools where the contacts continue to attend school and undergo daily testing, there are 61.
8 cases out of 100,000 students and staff per week (740 cases in 8,379,749 days)
.
The asymptomatic infection rate of contacts who provided PCR samples was 1.
From April 19 to June 27, they found that in schools where contacts were quarantined, 59.
Jon Deeks, a professor of biostatistics at the University of Birmingham, pointed out that although the absenteeism rate in schools that conduct daily tests is lower than that in quarantine schools, and the rate of covid infection is higher, the difference is too small to make people believe that this was not caused by accident
This study failed to show that daily exposure testing increased the number of people attending school (or) provided data to show that it was safe, but it showed that horizontal flow testing missed about half of the contacts who were infected by friends at school
The researchers concluded that “there is no evidence that switching from home isolation to daily contact testing increases the incidence of symptomatic coronavirus among students and staff”, but this does not prove that the intervention actually reduces the risk of transmission
