What is the R number, and why is it so important?

The reproduction number is not fixed. Instead, it changes as our behaviour changes, or as immunity develops.

Before any measures came in, the number was well above one and the conditions were ripe for a large outbreak. Successive restrictions brought it down, but it was not until full lockdown that it was driven below one.Counter-intuitively, this increase is probably due to the success in slowing the virus in society as a whole. As cases collapse in the community, the R value is largely reflecting what is happening in care homes.

Dr Adam Kucharski, of the London School of Hygiene and Tropical Medicine, told the BBC:"It's a big challenge making sure you're not loosening too much and increasing transmission." Unfortunately, there is no confirmation of how much each intervention affects the virus's spread, although there are estimates.

BBC at it again.

The R number should become pretty irrelevant once the top 4 groups have been vaccinated as they make up up to 90% of those hospitalised/dying with covid.

Only because of lockdown!

Its only important to media. While we have one we are infecting; no matter what the figure or where the dot is. As far as I can tell the media has been they only people who's interested.

The R number varies according to the number of +ve tests the Govt need for that particular week.

oh ffs hurry up and jab the fannies and let’s us get in with it!

Propaganda days

BBCScotlandNews Extremely contagious Covid-19 depends on humans getting close to each other to spread the infectious killer.

which model are you basing this on then, one made in 1972? Terrorist media lying to the public again, PS taken a look at how many ppl have cxd their tv licences this week? I know of least 25 and thats just ppl at work !

My “R” number refers to the number of glasses of red wine I have a week. It’s gone up a bit since lockdown due to COVIDー19 😬

Well it's not important and you damn well know it lmao 😂 🤣 🤣 🤣

It is so important as it helps to control the masses

I know the B number is off the charts Media Bullshit

From FatEmperor , if Nobel prize winners are saying lockdown effectively added nothing why is this not on main stream media?!

The R number should have been a mathematical formula incorporating recent and current infections and including data such as Hospital admissions. Instead it is a model which takes a super computer 56 hours to process. It’s drivel

R? R is not a number. R is a letter. Like, ABCDEFG...R..? ? The fuck?

Now explain how they get the R0 number, how do they know for example it’s 0.7 or 0.5 & when it moves up or down. Is it from the testing, ummmm, no as they don’t test sufficient numbers. Is it from the social distancing monitoring, say the app, ummmm no, it’s not working.

Subliminal messaging Stay at home Stay at home Stay at home

Ask this fuckwit

until it goes up and may scupper govt plans. Then it seems R isn’t one number but has “different measures”.

To set up the joke that our government doesn’t know its Rs from its elbow?

Something that will be forgotten about and never mentioned again, if it’s too high for the government to be able to do what they want.

It's only important StayAtHomeSaveLives when it suits the government's agenda unfortunately StayAlert

Also important is the F number. The number of Fear spreading and not diminishing. Potentially far more damaging.

We the better word should be Chinavirus because it's originated from China, and the World Leadership must place Economic Sanction on Chinese Government for killing these innocent people..what is their offense and why the Global Death Sentence from China😠
