Coronavirus - Prerequisites for Lifting Lockdown within the UK

April 21, 2020 business

Living in West London through the lockdown imposed as a consequence of the Coronavirus outbreak is a surreal experience. Normal existence, similar to we oknew less than two months ago, seems to have happenred in another lifetime. Some of us older ones lived through the nervous uncertainties of the Cold War and we all look with some trepidation at the imminent challenges posed by local weather change. But this is something altogether different.

As a 58-yr-old diabetic male my vulnerability in the face of this virus is heightened. As is that of my son, who’s asthmatic. Neither of us is listed among the 1.5 million most vulnerable as recognized by the UK authorities, however we’re open enough to problems for us to have gone voluntarily into more or less full isolation, along with the remainder of the household who are supporting us. Numerous in-laws and outlaws appear to be attempting their degree best to tempt us out into the perilous yonder, but to this point we’re holding firm.

Readily available data

I am neither a virologist nor an epidemiologist. I’m not even a statistician. But I’ve an O-level in Mathematics. And modest although this achievement could also be in the wider scheme of academia it is enough to enable me to determine developments and to draw conclusions from data that is readily available to anybody with a connection to the Internet and a working data of Google. Which is why I shudder at the evident bemusement of a lot of these commentators who pass for experts.

All through its dealing with of the disaster, my authorities has been eager to emphasize that it’s “following the science”. Political spokespersons are invariably accompanied during briefings by medical advisers and scientists aplenty of order and esteem. And yet what passes as the best of scientific advice in the future seems so often to fall by the wayside the next. Thus our initial reluctance to suspend giant sporting events was primarily based on “scientific advice” which stated there was no evidence that enormous crowds of individuals packed intently collectively introduced an excellent setting in which a virus may spread, only for opposite advice to be issued barely a day or two later. Likewise pubs and restaurants. “Following the science” has even been offered as an explanation for deficiencies in the provision of protective equipment to frontline workers and in testing capacity. One might be forgiven for wondering whether political coverage was being informed by the science, or vice versa.

Long plateau

That was then. At present we’re in lockdown, and the dialogue has moved on to how we are going to get out of it. A lot flustered navel gazing inevitably ensues because it dawns upon the nice and the good, political and scientific, that a dynamic market economic system can’t be held in suspended animation forever. So the place does all of it go from here?

If one needs to know what is likely to happen in the future, the past and certainly the present often function helpful guides. And there is sufficient info to be discovered in the statistical data that we have collated since the initial outbreak in Wuhan, by way of the exponential pre-lockdown increases in the number of infections and deaths and on to the more welcome signs that have more just lately begun to emerge from Italy and Spain, to offer us some idea of the place we’re headed.

Initially, the long plateau followed by a gradual decline in the numbers reflects the less drastic approach taken by the European democracies than was adopted by China. When crisis comes there is usually a price to pay for enjoying the benefits of a free and open society. In southern Europe the descent from the “peak” of the outbreak is noticeably slower than was the original climb. With the United Kingdom’s shutdown being less severe even than Spain’s or Italy’s, the unlucky truth is that we will count on our recovery from this first peak, when it comes, to be a good more laboured one.

The reproduction number

The essential reproduction number is the mathematical term utilized by epidemiologists to quantify the rate of an infection of any virus or illness. Experts have calculated that, when left unchallenged, the reproduction number (or R0) of Covid-19 is around 2.5. This signifies that each contaminated individual will, on common, pass the virus to 2.5 different people, leading to exponential spread.
