My jaw slightly dropped yesterday when @michaelgove announced that the number of #Covid19 cases in the UK was now doubling every three to four days. This is significantly faster than the five days that was initially built into the government's forecasts for the rate of...
increase in sufferers, and the 4.3 days that @neil_ferguson told me on 17 March was the new estimated "baseline" doubling time. On the one hand, this accelerated rate of infection explains why the government moved to enforce much more severe measures to restrict...
social interaction just over a week ago, because presumably its scientific advisers had more than an inkling that the virus was spreading significantly faster than would allow hospitals to cope. To be clear, the acceleration in the number of reported cases does not mean the...
new restrictions on our ability to mix with people have failed. The @CMO_England and @uksciencechief believe there is a two to three week lag between the introduction of social-distancing measures and the rate at which the virus spreads through the population...
But it is now 12 days since @BorisJohnson announced a first round of restrictions on our ability to socialise or be close to other people and so it would be concerning if the rate of spread of the infection did not slow at all next week. And another thing. If @uksciencechief's...
heuristic - that for every death, there are probably 1000 infections in the country, though many not showing up in official figures - holds true, that means there are currently more than 750,000 people with the virus in the UK, and there will be well over a million...
within a day or two. Of course many of that million would not show symptoms for days, and many will never show symptoms (though as I've written before, one of the great frustrations for the government in managing the crisis is it doesn't know how many people get the virus...
without experiencing symptoms). But let's assume that the government's Scientific Advisory Group on Emergencies is correct, and 8% of those with the virus will require hospitalisation. That would imply that in the coming three weeks the NHS would have to treat some 80,000...
sufferers - which would exhaust the 33,000 NHS beds that have been liberated or created for Covid19 patients. That said, I am unclear whether the denominator for that 8% includes those with the virus who will never show symptoms, namely the asymptomatic. But even if the 8%...
applies only to those with symptoms, it is already pellucidly clear that the NHS will struggle to cope, even with the addition of the new beds at the Nightingale Hospitals, which are being created at exhibition centres. For what it's worth, the government is working on the...
assumption it will know in a fortnight it it has done enough to "flatten the peak" of the outbreak. I fear we'll know whether @BorisJohnson and his team have taken adequate pre-emptive action somewhat earlier.
PS I was using yesterday’s infection and mortality stats when writing. But with today’s news that there have been 1,019 deaths since the outbreak began, we are already at 1m UK people infected, if @uksciencechief’s heuristic or rule of thumb is correct
