Hey bud.Hi mate,
Whilst in principle I wholeheartedly agree with what you are saying, there is a major flaw in this concept.
Liken a Covid test to a cars annual MOT test, all it proves is that at xxx time, on xxx day you did not have Covid. However within half an hour of leaving the test centre you may catch it on your way home, and from then on you have supposedly tested negative, but are infecting other people all the time.
Now this approach may have been effective if started in say Jan Feb this year, but with the situation now you would have to be able to test the entire population of the UK (circa 68 million) every two, or three days, that would mean 10 million tests a day just to test everyone weekly.
The ideal time to test people would be now, with the new 4 week lockdown in place, but to have everyone tested in four weeks would mean 2.5 million tests a day to complete, and what's our capacity at the moment, 200,000 and that has never been reached in practice.
So, as I say it is a good idea, but not achievable, even though the Chinese figure of testing an average of one million people a day sounds impressive the population of China is 1.4 billion, so when that is added to into the math's, they face the same problem in reality.
Looks like they're going to do it in Liverpool. Also saw something about another town somewhere else in the country with 36000 people that they're going to blanket test.
If the testing is carried out efficiently and quickly the people who catch the virus after being tested could be negligible. Besides, they could test more than once - twice, a few days or a week apart for instance.
And besides, none of this is about eradicating the virus. I see so many people post online that lockdown is pointless because the virus will come back. The whole point of these lockdowns isn't to eradicate the virus, it's to suppress the spread of the virus so that the healthcare system doesn't get overwhelmed. There will ALWAYS be some people catching the virus regardless of what we do in terms of lockdown and testing. But it buys time and saves lives between now and when a vaccine becomes available.
