Yet the World Health Organisation (WHO) has just
declared monkeypox a global health emergency, which is a big deal. The only
other infectious diseases in that category are Covid-19, which has already
killed 6.4 million people, and polio (which is trying to make a come-back).
Targeting monkeypox seems disproportionate, but there’s a reason.
“Covid-19 is broadly viewed as being a ‘once in a lifetime’ or ‘once in a
century’ pandemic. Modeling work based on historical data shows that this is
not necessarily the case,” reported the epidemiological start-up Metabiota last
year. That’s because “the frequency of ‘spill-over’ infectious diseases like
Covid is steadily increasing.”
It’s increasing because quick-killer pandemic diseases only started thriving in
human societies when we began living together in large numbers. Lethal viruses
and bacteria probably always ‘spilled over’ into human populations from time to
time, but if they infected little hunter-gatherer groups of 50 or 100 people
they just died out along with the victims.
The natural home of those diseases were birds and animals that lived in big
flocks and herds: lots of potential victims to sustain the transmission. But
when human beings started living in big civilisations and domesticated some of
those animals, the pandemic diseases happily transferred across and thrived
amongst us too.
For most of the history of civilisation, successful transfers didn’t happen all
that often: big new killer pandemics only came along every five hundred years
or so. However, now that there are eight billion people and millions
criss-cross the planet every day, the disease vectors have more opportunities
to spread and they move much faster.
At the moment, according to Metabiota’s calculations, it’s even odds that we
will have another new pandemic on the scale of Covid-19 in the next 25 years.
More precisely, they estimate the probability of another global pandemic as
deadly as Covid to be between 2.5-3.3 percent each year. It could even arrive
next year.
Monkeypox is not that disease. Despite its rapid spread to so many countries,
it is transmitted mainly between men who have sex with men. There is an
existing, fully effective vaccine for it (the same one that eradicated
smallpox, which no longer exists in the wild). And hardly anybody dies from it.
So WHO director-general Dr. Tedros Adhanom Ghebreyesus had some explaining to do
when he broke a stalemate at his ‘emergency committee’ and decreed that
monkeypox is a global emergency.
He explained that it was to speed up research on “the new modes of transmission
that have allowed it to spread”, and to press countries to use vaccines and
other measures to limit the numbers infected. These are all sensible things to
do, but they really don’t justify declaring a global health emergency.
What he carefully avoided saying is that he really intends it as a reminder of
our peril and a spur to action. The whole pandemic response system needs an
exercise that incorporates all the lessons learned from our stumbling response
to Covid, and monkeypox provides an excuse to do it.
Ghebreyesus is manipulating the system in a well-meant attempt to persuade
the world to build better systems for containing dangerous emergent diseases in
general, and he may come under serious fire for doing so.
But you can see his point because we haven’t learned enough from our harrowing
experience with Covid. The vaccines were developed faster than in any previous
pandemic, and two-thirds of the world’s population has been fully vaccinated in
about sixteen months, but the rate of immunity in the poorest countries is
abysmal.
That leaves reservoirs of high infection that serve as breeding grounds for new
variants of the virus, some of which may be able to evade the vaccines. This is
an issue of distribution and organisation, not a medical issue, and doing it on
a smaller scale for monkeypox could improve the system for the next time
something truly dangerous appears.
The same goes for the initial phases of detection and containment, which were
badly bungled with Covid. There will be much worse pandemics coming down the
road in the future – WILL BE, not ‘may be’ – and the world needs to be better
prepared.
Just spending one-hundredth of what the world spent on fighting Covid to
improve global readiness for dealing with the next pandemic – building local vaccine production facilities, regional labs with good analytical
capabilities, and stronger reporting networks – could spare us another two
years of the misery and loss we had with this pandemic.
If that’s Ghebreyesus’s real goal with this monkeypox business, it’s all right
with me.
