Send all children Back To school and relieve parents Back To Work - could trigger a second wave of Corona-Virus, warn researchers.

UCL and the London School of Hygiene and Tropical Medicine team said that testing and tracing of contacts of people with The Virus could help prevent this.

But the current test-and-trace system would be in order to be effective.

The First , an assessment of the extent of contact tracing needed to prevent a second wave.

with the computer models to see how The Virus is spread as the students returned to the classroom and their parents were exempt from the child care and be able to return to Work or to other activities.

the scientists studied The impact of the "phased-return" strategy in England.

have you investigated what happens if the reception, year 1 and year Six go Back To the beginning of June, followed by all the primary school pupils, who In July ; the upper school in year 10 and 12 go with some contact In July , and all of the secondary schools back in September.

The study showed that the combined effect on students and parents would be enough to make it to a second shaft without an effective test-and-trace program.

This would happen, to December 2020, and would be twice as large as the First Peak , unless the government has other measures, such as re-imposition of the lockdown.

How to test and trace works:

the success of The system depends on how well The Testing and contact tracing goes.

The Model proposed that a second wave would be prevented if:

the modeling of Crystal Ball , and there is uncertainty to any forecasts, is always. But researchers are concerned, England is the achievement of these figures.

About 1,700 people tested positive, the figures from The Office for National Statistics suggest Every Day in hospitals, care homes and the wider community, while, there are 5,600 new infections A Day in the community Alone - and a Public Health England report.

There are no official data on The Number of contacts searched, but.

"Our concern from the data at The Moment is test-trace-isolate is not on the cover, which we think is the minimum," Prof Chris Bonell, from the London School of Hygiene and Tropical Medicine, told The Bbc .

"It is clearly a risk for a second pandemic wave... I'm worried. The R [rate of virus spread] is a little bit smaller than one is [The Point at which The Number of new cases begins to Take Off again], but the incidence is high, it is so precarious. "

Dr. Jasmina Panovska-Griffiths from UCL, said it would have been better to wait until test and the trace was fully up and running, before lifting the lockdown.

"cases don't get as much as we wanted. I would caution against the re-opening of the schools, if we do a lot of other interventions, and we do not know the effects of them.

"Everything depends on control of transmission, there is The Threat of a second pandemic wave. "

Meanwhile, researchers at the University of Warwick also have modeling published on the impact of the re-opening of the schools. It not only looked at the influence of children mix, the society-wide effect schools open.

It was found that a halving of the size of the classes, or the concentration on younger and younger children in the school was less likely to press the R number is above 1, The Point at which The Number of new cases begins to Take Off again.

secondary schools were considered to be more risky, as the older children come in contact with more people.

"If we open all the schools, it might be said to push R above 1 in some regions," Dr. Ed Hill .

But he added: "decisions surrounding the re-opening of the schools are in a difficult trade-off between the epidemiological impact and the needs of The Children in the school-based development. "
