politicians say they Are following the science on coronavirus. So What is the science About the easing of the blockade rules?

Prime Minister Boris Johnson has with "baby-steps".

Changes will be gradual to avoid The Risk of a second peak of infections could overwhelm the NHS

And, he says, The Plan is dependent on infection and death rates remain low.

And if there Are any signs of it, you begin to descend, the brakes go on again.

These Are some of the considerations behind This Week 's most important announcements.

Why Are the youngest children due to return to school first?

One of the reason why it is suggested that young children should go Back To school, from the beginning of June.

the reception, year 1 and year 6 children were The First to return.

as well As with special educational needs, it is suggested:

Young children Are , as a group, high-risk, when It Comes to the flu.

But they appear to be at low risk, that they Are very sick with Covid-19.

the experts do not know, however, is the extent to which you can wear, coronavirus and the disease spread to the adults and to each other.

And from The Return to school with only a few year groups, to enable them to assess the impact on the rate of infection.

the Younger pupils find it to use perhaps more difficult, face-coverings, which Are not recommended for children, and follow social distancing rules, however.

So the focus is to wash the hands and other hygiene measures.

Why do I meet only one person?

In Theory , meetings of two or more People at the same time from the same budget, roughly the same risk of infection, such as a meeting.

But health Secretary to Matt Hancock BBC Radio 4 told the Today programme, the one-person rule would hold meetings of People from different households Are smaller, Making It easier to stay, to remain to the basic principle to 2m (over 6 ft).

Somewhere Between 1-2m is widely recognized throughout The World as the distance within which the greatest risk for inhalation of droplets from another person coughing and sneezing.

The Best Evidence suggests coronavirus is most common these droplets spread by entering through The Eyes , nose and mouth, either directly or after touching a contaminated object.

But there is some evidence that can form The Virus , aerosols, clouds, lighter particles, which hang around in the air for longer, especially in hospitals during procedures such as intubation.

Why is it OK, spend more time outdoors?

activities such as golf and tennis will be allowed, but.

the person of another household.

But social distancing rules continue to apply.

And playgrounds and outdoor gyms, where there is a higher risk of close contact and touching surfaces, is closed.

Once sold, the droplets will sink relatively quickly to the ground.

However, indoor environments have to land more surfaces for you, the Touch of other - and less ventilation.

And independent scientific advisors say that The Risk of infection is significantly lower outside.

Why The Change in covers on the face, the rules?

As more and more People go Back To work, buses, tubes and trains will be better utilized.

And the government is now advising People covering wear a face, if you come in contact with others, they do not usually meet, in closed spaces, where the social distance is not always possible - for example, in Public Transport or in some stores.

The science behind the advice rather sketchy and controversial.

But there is some evidence face covers could help stop People who Are contagious but have no symptoms of unknowingly spread The Virus .

Why Are the Nations, the things different?

One of The The government says must be met before the lockdown eases considerably, reduces the rate of infections Are "manageable level".

- how many People each infected person, the disease passes - must be well under one.

At The Moment , the R-series in the UK, it is estimated that between 0. 5 and a.

But it is thought to be higher in Scotland, Wales and Northern Ireland .

So There is less room for restrictions to be eased.

Even in England there Are differences.

For example, the R is much higher than in care homes and hospitals, where there Are more cases of the disease.

Outside of these settings, the spread of the Corona Virus in the Community seems to have been reduced, possibly to below epidemic levels, according to The Office for National statistics (ONS).

He estimates that 0. 24% of People in General - About 136,000 People Are currently infected with coronavirus, based on Tests of a representative sample of More Than 7,000 People in England, the between 26. April and 8. May.
