this afternoon I
watched the Minister for Care, Helen
Whately,
trying to give a reassuring message that the government had an
effective strategy for dealing with the SARS-02
virus which when it infects humans causes the disease now known as
Covid19.
What she did not explain
is why the UK is following a strategy which differs from that being
followed in Spain and Ireland, recommended as good practice by the
World Health
Organisation (WHO)
and vigorously pursued by China. That it
works is evidenced by the massive decline in new cases in China in
recent days and the fact
that the it is now advising Italy about the measures to be taken to
defeat the outbreak.
Following
WHO guidance other countries affected by the disease are pursuing a
policy of ‘contain
the disease and eliminate the virus’.
That’s not easy and
it is expensive. As well as hospitalising and treating those who are
suffering from the disease you have to find the people they have been
in contact with and isolate them until they either show signs of the
disease or you can be sure that the incubation period is over.
Boris
Johnson and his
government prefer the cheapskate option of letting the virus infect
at least 60% of the us so that the survivors will no longer be at
risk from infection and so transmission of the virus will come to an
end and it will disappear. It has the grandiose title of ‘herd
immunity’
which makes
it sound a medically respectable strategy.
A
more honest appraisal of it is that Johnson and his government are
proposing to use the UK population as guinea pigs and are quite
prepared to see a lot of people die as ‘collateral
damage’.
This
is a purely political decision. If it really is ‘science based’
as
is claimed
then that evidence needs to be placed in the public domain so that it
can be independently
evaluated
by people who are less close to government than Chief
Scientific Adviser, Sir
Patrick Valance
and
Chief Medical Officer, Professor
Chris Whitty.
These
two seem happy to provide cover for the political decisions being
made
by Johnson.
As
I pointed out in an earlier article if 60% of a UK
population
of 60 million people become infected with the
virus
causing the disease Covid19 that is 36 million people. The mortality
rate for those infected is 1%, that translates to 360,000 deaths.
Not everyone infected with the virus will show symptoms, but as the
mortality rate for those who do show symptoms is about 4% we can
estimate that the total number of people who will
be infected and
show symptoms, will be about 9 million people. Of these 80% will
recover without hospitalisation,
15% will require oxygen and 5% will require to be artificially
ventilated. In
other words 1.8 million of those 36 million it is assumed will be
infected, will need hospitalisation.
If
we assume that the virus is with us for 18 weeks of the summer and
the infection curve is fairly flat that means there will be a
requirement for space for a 100,000 patients of which 75,000 will
need oxygen and 25,000 will need to be artificially ventilated EACH
WEEK.
If the infection curve is not flat and is sharply peaked these
figures will be much higher for a short time.
I
have
based these figures on the information provided by the WHO and UK
government assumptions about the proportion of the population who
need to be infected to produce ‘herd
immunity’.
If
you don’t like the message don’t shoot the messenger.
If you are sceptical about
whether the NHS will be able to cope with 100,000 high maintenance
patients a week for much of the summer you are not alone.
When
the weekly death toll starts to move into four figures Tory MPs will
get jittery: when
granny and grandad die gasping for breath, Johnson’s ‘Red
Wall’
will be rubble.
