The Challenge

---

It is a simple, but crucial figure at The Heart of Understanding The Threat posed by the coronavirus. It directs the governments around The World on the actions required to save lives and to lift lockdown.

it is called the reproduction number, or simply the R-value.

What is R?

The reproduction number is a measurement of a disease is the ability to.

It is The Number of people an infected person, The Virus more

measles to give, on average, has one of the highest numbers in the city with a reproduction number of 15 in the population without immunity. It is explosive outbreaks can lead to.

The new coronavirus, officially known as Sars-CoV-2, to vary a multiplication of The Number of three, but the estimates.

How is R calculated?

you don't capture The Moment , people who are infected can; instead, scientific work in reverse.

With Data such as The Number of people die, to the hospital will allow you to assess how easily The Virus spreads, supplier, or tested positive for The Virus .

in General, this is a picture of what the R-series was two to three weeks. Regular testing of private households should soon have a more recent estimate.

Why is A Number at the top, a risky?

If the reproduction number is greater than one, then The Number of cases is rising exponentially - it snowballs as the debt on an unpaid credit card.

But if The Number is low, the disease finally, peter, because there is not enough New People are infected, to sustain the Outbreak .

If the R-value is above, then The Number of cumulative cases decreases, but if it is down then stops the Outbreak . The further down you are, the faster this happens.

want to force governments everywhere, the reproduction number to below about three (the R-number, if we no action) under a.

This is The Reason you have not seen the family, have to work from home and The Children were cutting out of school - stop people coming in contact with each other, The Virus has the ability to spread.

What is the R-series in the UK is?

The reproduction number is not set. Instead, it changes how our behavior changes, or as immunity develops.

Mathematical modeller at Imperial College in London trying to keep track of how The Number has changed, such as isolation, social distance, and full closure were introduced.

Before any action came, The Number was far above a, and the conditions were ripe for a major Outbreak . Consecutive restrictions brought it down, but it was not until full lockdown, that it was shut down.

The R-value in the UK recently and is now believed to be between 0. 7 and 1. 0.

Counter-intuitive, this increase is likely due to the successes in slowing The Virus in the society as a whole. As cases, the break-up of the community, the R-value is reflected in the largely what is happening in nursing homes.

Does R vary across the UK?

The R-number come down over any part of the United Kingdom since the beginning of the epidemic.

But several groups of researchers, that it came down, most of them in London. It proves to be far more stubborn in the North-East of England.

These figures are more optimistic than other groups' calculations. sets The Number for London at 0. 6, and the South-west at 0. 9.

He also showed the R-values were 0. 8 in Wales, and 1 in both Scotland and Northern Ireland .

how does this teach lift the lockdown?

Like every country thinks, for example, lifting, lockdown, the goal will be to keep the playback The Number below.

Dr. Adam Kucharski, London School of Hygiene and Tropical Medicine, told The Bbc : "It is not a big challenge, making sure you loosen it too much, and increase the transmission. "

However, it has a monumental effort, one that causes harm to the life of the people, to The Number of three to 0. 7.

"It's not a lot of space with give you to play with [The Number one]," Dr. Kucharski added.

What measures could be repealed?

Unfortunately, there is no confirmation of how much each intervention, The Virus has spread, although there are estimates.

"the Opening of school versus jobs compared to other meetings - to understand how much you can increase the reproduction number, is The Challenge ," said Dr. Kucharski.

Another Problem is that the behavior of people changes over time, so that The Number can creep on you, even if lockdown policies remain unchanged.

What is likely to be needed are New Ways , the control of The Virus , such as the more detailed Tests

This allows you to suppress the multiplication of The Number of targeted, so that some of The Other measures are to be lifted.

it is The Most important number?

reproduction number is one of the big three.

a More difficult degree - if you can relax a very mild illness that do not cause a lot of problems, then you a little. Corona Virus and the disease it causes, Covid-19, can be severe and fatal, unfortunately.

The Last is The Number of cases, to act the important for the decision of when. If you have a high number, but simple restrictions that the representation of The Number a is on, then you will continue to be a high number of cases.

What is a vaccine?

Having a further possibility to reduce the duplication of The Number .

A coronavirus patient would. of course, The Other three infect, on average, but if a vaccine could protect two of them from infection, then the reproduction would include The Number , from three to one
