“Viruses are not designed to damage or kill their hosts. The point of a virus is life, not death. Because viruses need living cells to reproduce over time, they have developed transmission strategies that make the finding of living hosts quick and efficient. Ideally, a pathogenic virus will enter a living system and have sufficient time to make many copies of itself before it is eliminated by the host’s immunological defenses. The virus survives and the host survives. That’s the model. The problem with pathogenic viruses — especially those hosts have not encountered before — is that, in the system’s efforts to find, and develop a means of neutralizing the virus, the state of the body is changed, sometimes beyond the point at which the body (especially weakened bodies) can remain alive. Consequently, it’s not the virus that kills, it’s the body’s reaction to the virus that kills.

The COVID-19 virus is special but not for the reason that most people think. Its infection of our bodies is nothing noteworthy as viruses go. But COVID-19 has also infected our cultures, our economics, and our politics, worldwide. It’s a virus and it’s a meme. In order to reduce the inferred levels of mortality in at-risk individuals our societies have reacted in unprecedented ways, by mandating the shut down of economic and cultural activities, curtailing the individual (and increasingly legal) rights of citizens, and by forcing both individuals and family groups into physical isolation for an, as yet, unspecified time interval. It remains to be seen whether these societal reactions will be sufficient to mitigate the damage the virus will inflict on human populations. In a moral sense, we have no choice but to endure them in the hope they will. But just as a body’s reaction to a pathogenic virus can leave it in a weakened state, and so susceptible to other infections that would not prove problematic had the virus not come along, the economic social and cultural reactions the COVID-19 meme has caused will leave our societal bodies in much weakened states.”
