Entering the New Decade: The Fear of Pandemics
As we step into the new decade, a looming fear over our health has taken center stage. The advanced mutation of the coronavirus has claimed thousands of lives since the first reported case in Wuhan, China. However, this is not humanity’s first encounter with a global pandemic. The emergence and spread of COVID-19 are but the latest in a long history of epidemics and pandemics, stretching back to the Byzantine Empire and continuing into the modern era.
Here are six epidemics and diseases that nearly brought humanity to the brink of extinction:
1. The Plague of Justinian
Historians believe the plague reached Constantinople via rats aboard grain ships from North Africa. The city was transformed into a hub of death and despair. Corpses were piled unburied, and the already struggling Byzantine economy—crippled by ongoing wars—spiraled further into collapse.
The Plague of Justinian serves as a testament to the role of media in sensationalizing events. Historian Procopius wrote, “All of humanity was on the brink of death” (an exaggeration) and described Justinian as “a demon in human form bent on annihilating his people” (highly implausible).
2. The Black Death
In 1347, Europe faced one of history’s most devastating pandemics: the Black Death. Scholars continue to investigate its origins, with most agreeing that the outbreak began in China.
Interestingly, some historians suggest the Black Death’s arrival in Europe was an early instance of biological warfare. During their siege of the Crimean city of Kaffa, the Mongols allegedly hurled plague-infested corpses over the city walls, spreading the disease to its inhabitants. In a desperate bid to escape infection, the city’s residents fled to places like Venice, unknowingly carrying the disease with them. One historian remarked, “They seemed to sail as though carrying the souls of the damned.”
Regardless of how the disease spread, its impact on Europe was catastrophic, wiping out over 60% of the population. A French historian vividly described mass burials: “Bodies were stacked in layers, with earth between them, resembling lasagna made of pasta and cheese.”
3. The Great Plague of London

In 1665, the Great Plague claimed the lives of a quarter of London’s population. Though limited to the city, its effects were nightmarish for residents living amidst filth and squalor.
The poor bore the brunt of the disease, dying in streets filled with animal dung and other refuse. Red crosses ominously marked the homes of the infected, while the wealthy—including King Charles II—fled to the countryside in search of safety.
Diary writer Samuel Pepys captured the grim atmosphere: “Only the wretched poor roamed the streets. The groans of the afflicted echoed day and night, accompanied by the tolling bells for the dead.”
Fortunately, the Great Plague’s duration was brief. Many believe the Great Fire of London in 1666 played a significant role in eradicating the disease.
4. The Third Cholera Pandemic
Caused by bacterial infection, cholera is a deadly disease that causes dehydration and death. During its third global outbreak in the mid-19th century, millions lost their lives.
The pandemic, originating in India, eventually spread worldwide and became a turning point in understanding disease prevention.
At the time, the “miasma theory” posited that diseases like cholera were caused by “bad air” from decaying matter. Social reformer Edwin Chadwick famously claimed, “Every foul smell is a disease.”
Yet one man, Dr. John Snow, challenged this view with a methodical investigation. He discovered that cholera cases in London’s Soho district were linked to a contaminated water pump. By convincing authorities to remove the pump handle, he effectively stopped the outbreak. Today, Londoners celebrate this as a milestone in public health.
5. The Spanish Flu
When the Spanish Flu first appeared in 1918, its severe symptoms were mistaken for a mere “cold.” Authorities downplayed the threat, preoccupied with World War I.
Despite its name, the flu didn’t originate in Spain. As a neutral country during the war, Spain’s uncensored press reported extensively on the outbreak, leading many to falsely associate the disease with the country.
The pandemic—caused by the H1N1 virus—spread rapidly, aided by troop movements across Europe. It ultimately claimed over 100 million lives. Recent pandemics like swine flu have rekindled interest in studying the Spanish Flu to prevent future disasters.
6. HIV/AIDS
Scientists believe HIV originated in Africa and crossed to humans in the 20th century. Analysis of preserved tissue samples suggests it had infected people long before its discovery. One early case involved Robert Rayford, a 15-year-old boy who died in 1968.
During the 1980s and 1990s, AIDS devastated communities, especially among gay men in the West and Africans. The stigma surrounding the disease compounded the suffering of those affected.
To date, HIV/AIDS has claimed an estimated 32 million lives. Fortunately, advances in medicine have transformed the prognosis for those infected, enabling them to live longer, healthier lives with proper treatment.
Humanity has faced numerous pandemics throughout history, each leaving indelible scars. While science has advanced, the lessons of the past remain vital in preparing for future health crises.
