Consider this unfortunately
familiar scenario. Several months ago a highly infectious,
sometimes deadly respiratory virus infected humans for the first time. It then proliferated faster
than public health measures could contain it. Now the World Health Organization (WHO)
has declared a pandemic, meaning that it’s spreading worldwide. The death toll is starting to rise
and everyone is asking the same question: when will the pandemic end? The WHO will likely declare
the pandemic over once the infection is mostly contained and rates of transmission drop
significantly throughout the world. But exactly when that happens depends on
what global governments choose to do next. They have three main options: Race through it, Delay and Vaccinate,
or Coordinate and Crush. One is widely considered best,
and it may not be the one you think. In the first, governments and communities
do nothing to halt the spread and instead allow people to be exposed
as quickly as possible. Without time to study the virus, doctors know little about
how to save their patients, and hospitals reach peak capacity
almost immediately. Somewhere in the range of millions
to hundreds of millions of people die, either from the virus
or the collapse of health care systems. Soon the majority of people
have been infected and either perished or survived
by building up their immune responses. Around this point herd immunity kicks in, where the virus can no longer
find new hosts. So the pandemic fizzles out
a short time after it began. But there’s another way to create
herd immunity without such a high cost of life. Let’s reset the clock to the moment
the WHO declared the pandemic. This time, governments and communities
around the world slow the spread of the virus
to give research facilities time to produce a vaccine. They buy this crucial time through tactics
that may include widespread testing to identify carriers, quarantining the infected
and people they’ve interacted with, and physical distancing. Even with these measures in place,
the virus slowly spreads, causing up to hundreds of thousands
of deaths. Some cities get the outbreak under control
and go back to business as usual, only to have a resurgence and return to physical distancing
when a new case passes through. Within the next several years, one or possibly several vaccines become
widely, and hopefully freely, available thanks to a worldwide effort. Once 40-90% of the population
has received it— the precise amount varying
based on the virus— herd immunity kicks in,
and the pandemic fizzles out. Let’s rewind the clock one more time,
to consider the final strategy: Coordinate and Crush. The idea here is to simultaneously starve
the virus, everywhere, through a combination of quarantine,
social distancing, and restricting travel. The critical factor
is to synchronize responses. In a typical pandemic,
when one country is peaking, another may be getting its first cases. Instead of every leader responding
to what’s happening in their jurisdiction, here everyone must treat the world
as the giant interconnected system it is. If coordinated properly, this could end
a pandemic in just a few months, with low loss of life. But unless the virus is completely
eradicated— which is highly unlikely— there will be risks of it escalating
to pandemic levels once again. And factors like animals carrying
and transmitting the virus might undermine
our best efforts altogether. So which strategy is best for this deadly,
infectious respiratory virus? Racing through it is a quick fix,
but would be a global catastrophe, and may not work at all
if people can be reinfected. Crushing the virus through Coordination
alone is also enticing for its speed, but only reliable with true
and nearly impossible global cooperation. That’s why vaccination, assisted by
as much global coordination as possible, is generally considered to be the winner; it’s the slow, steady,
and proven option in the race. Even if the pandemic officially ends
before a vaccine is ready, the virus may reappear seasonally, so
vaccines will continue to protect people. And although it may take years to create, disruptions to most people’s lives
won’t necessarily last the full duration. Breakthroughs in treatment
and prevention of symptoms can make viruses much less dangerous, and therefore require less extreme
containment measures. Take heart: the pandemic will end. Its legacy will be long-lasting,
but not all bad; the breakthroughs, social services,
and systems we develop can be used to the betterment of everyone. And if we take inspiration
from the successes and lessons from the failures, we can keep the next potential
pandemic so contained that our children’s children
won’t even know its name.
The end of this is great. Hopefully this does spark some much needed change not just in the US, but worldwide.
I’m fascinated to see which country gets a legitimate vaccination first.
I'd rather get coronavirus at this point then have to stay locked inside for another 3 months, the emotional strain of doing nothing for 3 months was absolutely terrible, and was much worse then any sickness I have ever had. My mind was depressed the entire time.
