Finally, 2020 is coming to an end, but the agony its viral pandemic inflicted on the entire world population will continue for a long time. And much as we would like to forget its damaging effects, it will surely be etched into our brains for the rest of our lives. The children who suffered the pain of the coronavirus disease 2019 (COVID-19) pandemic will endure its emotional scars for the rest of the 21st century.

Reading about the plagues of the past doesn’t come close to experiencing it and suffering through it. COVID-19 will continue to have ripple effects on every aspect of life on this planet, on individuals and on societies all over the world, especially on the biopsychosocial well-being of billions of humans around the globe.

Unprecedented disruptions

Think of the unprecedented disruptions inflicted by the trauma of the COVID-19 pandemic on our neural circuits. One of the wonders of the human brain is its continuous remodeling due to experiential neuroplasticity, and the formation of dendritic spines that immediately encode the memories of every experience. The turmoil of 2020 and its virulent pandemic will be forever etched into our collective brains, especially in our hippocampi and amygdalae. The impact on the developing brains of our children and grandchildren could be profound and may induce epigenetic changes that trigger psychopathology in the future.1,2

As with the dinosaurs, the 2020 pandemic is like a “viral asteroid” that left devastation on our social fabric and psychological well-being in its wake. We now have deep empathy with our 1918 ancestors and their tribulations, although so far, in the United States the proportion of people infected with COVID-19 (3% as of mid-November 20203) is dwarfed by the proportion infected with the influenza virus a century ago (30%). As of mid-November 2020, the number of global COVID-19 deaths (1.3 million3) was a tiny fraction of the 1918 influenza pandemic deaths (50 million worldwide and 675,000 in the United States4). Amazingly, researchers did not even know whether the killer germ was a virus or a bacterium until 1930, and it then took another 75 years to decode the genome of the influenza virus in 2005. In contrast, it took only a few short weeks to decode the genome of the virus that causes COVID-19 (severe acute respiratory syndrome-related coronavirus 2), and to begin developing multiple vaccines “at warp speed.” No vaccine or therapies were ever developed for victims of the 1918 pandemic.

An abundance of articles has been published about the pandemic since it ambushed us early in 2020, including many in Current Psychiatry.5-21 But these publications don’t do justice to the emotional toll of living through the pandemic and witnessing its multi­farious repercussions (Table). It was truly bizarre and shocking for us to see our society and all its components literally come to a standstill, forcing the population to stop working, reducing us to simply “existing” inside our homes, with no socializing, traveling, or interacting. More unbearable than the sudden emptiness and paralysis was the unremitting fear, laced with a profound uncertainty of what was to come or when it would end.

The multifaceted impacts of the COVID-19 pandemic

Most psychiatrists are familiar with the Holmes and Rahe Stress Scale,22 which contains 43 life events that cumulatively can progressively increase the odds of physical illness. It is likely that most of the world’s population will score very high on the Holmes and Rahe Stress Scale, which would predict an increased risk of medical illness, even after the pandemic subsides.

Exacerbating the situation is that hospitals and clinics had to shut down most of their operations to focus their resources on treating patients with COVID-19 in ICUs. This halted all routine screenings for cancer and heart, kidney, liver, lung, or brain diseases. In addition, diagnostic or therapeutic procedures such as endoscopies, colonoscopies, angiograms, or biopsies abruptly stopped, resulting in a surge of non–COVID-19 medical disorders and mortality as reported in several articles across many specialties.23 Going forward, in addition to COVID-19 morbidity and mortality, there is a significant likelihood of an increase in myriad medical disorders. The COVID-19 pandemic is obviously inflicting both direct and indirect casualties as it stretches into the next year and perhaps longer. The only hope for the community of nations is the rapid arrival of evidence-based treatments and vaccine(s).
