Coronavirus - Prerequisites For Lifting Lockdown In The UK

Coronavirus - Prerequisites For Lifting Lockdown In The UK

Living in West London during the lockdown imposed as a consequence of the Coronavirus outbreak is a surreal experience. Normal existence, such as we oknew less than two months ago, appears to have occurred in one other lifetime. Some of us older ones lived by 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 within 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 are open enough to problems for us to have gone voluntarily into more or less full isolation, together with the rest of the household who're supporting us. Various in-laws and outlaws appear to be making an attempt their stage best to tempt us out into the perilous yonder, however up to now we're holding firm.

Readily available data

I am neither a virologist nor an epidemiologist. I am not even a statistician. However I have an O-degree in Mathematics. And modest though this achievement could also be within the wider scheme of academia it is sufficient to enable me to determine trends and to draw conclusions from data that is readily available to anybody with a connection to the Internet and a working information of Google. Which is why I shudder on the evident bemusement of many of these commentators who pass for experts.

Throughout its handling of the disaster, my government has been keen to emphasize that it is "following the science". Political spokespersons are invariably accompanied during briefings by medical advisers and scientists aplenty of order and esteem. And but what passes as the very best of scientific advice one day seems so often to fall by the wayside the next. Thus our preliminary reluctance to suspend large sporting events was based on "scientific advice" which acknowledged there was no evidence that large crowds of people packed closely collectively presented a great atmosphere in which a virus might spread, only for contrary advice to be issued barely a day or two later. Likewise pubs and restaurants. "Following the science" has even been offered as a proof for deficiencies in the provision of protective equipment to frontline workers and in testing capacity. One could possibly be forgiven for wondering whether or not political coverage was being informed by the science, or vice versa.

Long plateau

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

If one needs to know what is likely to happen sooner or later, the past and certainly the current often function helpful guides. And there may be enough info to be discovered in the statistical data that now we have collated for the reason that initial outbreak in Wuhan, through the exponential pre-lockdown will increase in the number of infections and deaths and on to the more welcome signs which have more just lately begun to emerge from Italy and Spain, to present us some thought of where we're headed.

Initially, the lengthy plateau adopted 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 can be a value to pay for having fun with 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 unique climb. With the United Kingdom's shutdown being less severe even than Spain's or Italy's, the unlucky fact is that we can anticipate our recovery from this first peak, when it comes, to be an even more laboured one.

The reproduction number

The basic reproduction number is the mathematical time period utilized by epidemiologists to quantify the rate of an infection of any virus or illness. Consultants have calculated that, when left unchallenged, the reproduction number (or R0) of Covid-19 is around 2.5. This means that every infected particular person will, on average, pass the virus to 2.5 other individuals, leading to exponential spread.
