contact-tracing App could help stop the Corona-Virus-pandemic, But 80% of today's smartphone owners would need to use it, experts, the NHS say advice.

The University of Oxford Big Data Institute.

If the lower intake is, say scientists, the App would still help slow down the spread of Covid-19.

they add that because the people was able to diagnose the disease is crucial.

This means the user only the answer on the screen of a questionnaire to be evaluated, a significant risk of infection. You would not be able to speak to a health adviser or wait for a medical test result.

This would send a cascade of alerts to the people you recently in the vicinity, advising them to go back into self-isolation.

The Experts say that "speed is of The Essence ", and that a delay in the identification of contact persons A Day from The Onset of symptoms can be the difference between epidemic control and resurgence.

"There are more people who would be receiving notifications as a result of false warnings," explains Prof Christophe Fraser.

"But , in fact, it leads to less days of people, in self-isolation and quarantine, as the effect of the suppression of the epidemic outweighs faster, the risks in waiting for a test before the announcement. "

in The course of the 70s were not taken into account, to remain on the basis that you would remain "shielded" from home, he added.

The University of Oxford, academics are a mix of epidemiologists, ethicists advice NHSX - health-service-to-digital Innovation Unit , the basis on which the contact tracing App will be created. They are not involved in programming or design of the software itself.

your model takes account of the different age groups, household structure and movement patterns, in an effort to try to maximize The Number of people that can be allowed to move freely, as soon as a contact-tracing App was launched.

"We look at the introduction of the App at The End of lockdown" Prof Fraser added.

"When you install it, it to start a couple of days of recording data, before it is fully functional. "

The Group first.

Since then, they have adapted to take your model into account the changing factors, including the fact that Covid-19 the infection rate was faster than she had expected.

you have changed plans with a system based on the GPS Position, readings, and scanning of QR codes, One that depends exclusively on Bluetooth signals. This was done to users ' privacy, which in turn could encourage take-up.

The Hope is that the use of the App , as well as other measures, such as hand washing and social distance of the vulnerable members of society, it is prevented that a second peak in the case of an infection or The Need for repeated national lock feature.

The Team estimates that 56% of the population have to use in General, to the App to stop the outbreak. Prof Fraser said, the same owner is set to 80% of all existing smartphone, based on data from Ofcom.

"This is a very ambitious target," The Professor acknowledged.

"It was not something that happened in the rule for a new App is also a very popular - But if we can explain that this Public Health intervention, the new and different.

"Some of my colleagues. Order large surveys in several European countries, including the UK.

"More Than 80% of respondents were somewhat or you install this App , if it was explained in detail what it would do. "

Also when there are less people to install the App , The Team estimated that an infection will be averted for every One to two users.

Opt-in App

The Oxford team suggests that the use of the Tools should be done on a voluntary Basis. However, this will be a challenge.

On the 20. March was Singapore, One of The First countries for the provision of a voluntary contact-tracing App that trace together.

installed, But only About 12 % of the population, and, after a sharp increase of new cases, the city-state introduced a lockdown on 7. April, the it is the as a "circuit-breaker".

To complicate matters, a small number of phones, which are still in use in the UK do not support Bluetooth Low Energy system is required, so that to reach the goal Even harder.

Prof Fraser said that the officials discussed smartphones, which involved with no, or cheaper, portable Bluetooth devices - in order to increase The Number of citizens.

NHSX is also interested to keep the App -opt-in.

we have started some already, exploring the impact of it is always mandatory.

Internet law expert Prof Lillian Edwards is stating that:

Others , including the and have doubt, whether contact-tracing applications have no chance of success and the fear of you might give you "false hope", the politicians are looking for a Way Out of lock have.
