The Zoe app estimates nearly 20000 cases per day compared to the official figures of between 6000 and 7000 is there a reason for this.
I remain befuddled because in absolute terms the risks are infinitesimal yet the caution and lockdown seem disproportionate to me at least. I cannot reconcile the damage of shutting schools and universities with the potential risk but am perhaps missing something.
Okay so the best guess is that the rate
per day in March was 100,000 new infections, and this was doubling every few days. So if we hadn't locked down it would effectively have gone through the majority of the country in the days and weeks following.
At peak around 1-3 million people were thought to be infected at one time. This was where the 1000 deaths a day came from.
The NHS however, was not completely overwhelmed at that point. In countries where healthcare was overwhelmed the death rate then rose to 3-4%.
So there could have been deaths well into 6 or 7 figures, without a lockdown.
We know only a limited amount about this pathogen, but it appears that having had the infection may not confer long term immunity and indeed, there are suggestions that t can be more dangerous when you get re-infected.
The clever thing in a pandemic historically has been to get people to avoid crowded placed- and shut down places like schools and universities where people gather. In the Middle Ages even, plagues led to interruption of studies. You don't want all your students to get infected.
Even without a vaccine, or antibiotics, a modern understanding of disease, plagues tend to die out after a couple of years. You want to lie low, avoid getting infected and survive to get on with your life.
re the figures, there's a problem with availability of testing, the Zoe figures reflect the numbers of people with relevant symptoms in the community. ONS will have more prevalence figures out on Monday which give a good estimate of current numbers, you could have a look at that maybe?
