At the moment, the Ebola virus is ravaging three countries – Liberia, Guinea and Sierra Leone – where it is doubling every few weeks, but singular cases and clusters of them are cropping up in dense population centers across the world. An entirely separate Ebola outbreak in the Congo appears to be contained, but illustrates an important point: even if the current outbreak (to which some are already referring as a pandemic) is brought under control, continuing deforestation and natural habitat destruction in the areas where the fruit bats that carry the virus live make future outbreaks quite likely.
Ebola’s mortality rate can be as high as 70%, but seems closer to 50% for the current major outbreak. This is significantly worse than the Bubonic plague, which killed off a third of Europe’s population. Previous Ebola outbreaks occurred in rural, isolated locales, where they quickly burned themselves out by infecting everyone within a certain radius, then running out of new victims. But the current outbreak has spread to large population centers with highly mobile populations, and the chances of such a spontaneous end to this outbreak seem to be pretty much nil.
Ebola has an incubation period of some three weeks during which patients remain asymptomatic and, specialists assure us, noninfectious. However, it is known that some patients remain asymptomatic throughout, in spite of having a strong inflammatory response, and can infect others. Nevertheless, we are told that those who do not present symptoms of Ebola—such as high fever, nausea, fatigue, bloody stool, bloody vomit, nose bleeds and other signs of hemorrhage—cannot infect others. We are also told that Ebola can only be spread through direct contact with the bodily fluids of an infected individual, but it is known that among pigs and monkeys Ebola can be spread through the air, and the possibility of catching it via a cough, a sneeze, a handrail or a toilet seat is impossible to discount entirely. It is notable that many of the medical staff who became infected did so in spite of wearing protective gear—face masks, gloves, goggles and body suits. In short, nothing will guarantee your survival short of donning a space suit or relocating to a space station.
There is a test that shows whether someone is infected with Ebola, but it is known to produce false negatives. Other methods do even worse. Current effort at “enhanced screening,” recently introduced at a handful of international airports, where passengers arriving from the affected countries are now being checked for fever, fatigue and nausea, are unlikely to stop infected, and infectious, individuals. They are akin to other “security theater” methods that are currently in vogue, such as making passengers take off their shoes and testing breast milk for its potential as an explosive. The fact that the thermometers, which agents point at people’s heads, are made to look like guns is a nice little touch; whoever came up with that idea deserves Homeland Security’s highest decoration—to be shaped like a bomb and worn rectally.
It is unclear what technique or combination of techniques could guarantee that Ebola would not spread. Even a month-long group quarantine for all travelers from all of the affected countries may provide the virus with a transmission path via asymptomatic, undiagnosed individuals. And even a quarantine that would amount to solitary confinement (which would be both impractical and illegal) would simply put evolutionary pressure on this fast-mutating virus to adapt and incubate longer than the period of the quarantine.
Treatment of Ebola victims amounts to hydration and palliative care. Transfusions of blood donated by a survivor seem to be the only effective therapy available. An experimental drug called ZMapp has been demonstrated to stop Ebola in non-human primates, but its effectiveness in humans is now known to be less than 100%. It is an experimental drug, made in small batches by infecting young tobacco plants with an eyedropper. Even if its production is scaled up, it will be too little and too late to have any measurable effect on the current epidemic. Likewise, experimental Ebola vaccines have been demonstrated to be effective in animal trials, and one has been shown to be safe in humans, but the process of demonstrating it effectiveness in humans and then producing it in sufficient quantities may take longer than it would for the virus to spread around the world.
The scenario in which Ebola engulfs the globe is not yet guaranteed, but neither can it be dismissed as some sort of apocalyptic fantasy: the chances of it happening are by no means zero. And if Ebola is not stopped, it has the potential to reduce the human population of the earth from over 7 billion to around 3.5 billion in a relatively short period of time. Note that even a population collapse of this magnitude is still well short of causing human extinction: after all, about half the victims fully recover and become immune to the virus. But supposing that Ebola does run its course, what sort of world will it leave in its wake? More importantly, now is a really good time to start thinking of ways in which people can adapt to the reality of a global Ebola pandemic, to avoid a wide variety of worst-case outcomes. After all, compared to some other doomsday scenarios, such as runaway climate change or global nuclear annihilation, a population collapse can look positively benign, and, given the completely unsustainable impact humans are currently having on the environment, may perhaps even come to be regarded as beneficial.
I understand that such thinking is anathema to those who feel that every problem must have a solution—or it’s not worth discussing. I certainly don’t want to discourage those who are trying to stop Ebola, or to delay its spread until a vaccine becomes available, and would even help them if I could. I am not suicidal, and I don’t look forward to the death of roughly half the people I know. But I happen to disagree that thinking about what such an outcome, and perhaps even preparing for it in some ways, is necessarily a bad idea. Unless, of course, it produces a panic. So, if you are prone to panic, perhaps you shouldn’t be reading this.
And so, for the benefit of those who are not particularly panic-prone, I am going to trot out my old technique of examining collapse as consisting of five distinct stages: financial, commercial, political, social and cultural, and briefly discuss the various ramifications of a swift 50% global population collapse when viewed through that prism. If you want to know all about the five stages, my book is widely available.
You are infectious as long as the virus is in your body! From day one! Symptoms are irrelevant! Does anyone actually have to think about that! It’s funny the things “experts” will say!
