Scientists and medical researchers have for generations have varied over the accurate depiction of a pandemic. Nonetheless, one thing everyone agrees on is that the word describes the widespread happening of complaints. This is in the plethora of what is typically anticipated in a geographical area. Cholera, bubonic plague, smallpox, and influenza are some of the most excruciating killers in human history. And outbreaks of these illnesses across foreign borders, are duly defined as a pandemic. A few of the worst pandemics and epidemics in history have destroyed societies. These terrible illness outbreaks still menace humanity. Still because of the advances in epidemiology we no longer face the same dire consequences.
The Black Death pandemic
The Black Death pandemic took place in the year 1347. It was the earliest significant European outburst of the second great plague pandemic. This happened over the 14th to 18th centuries. In 1347 the plague came to the Crimea. It passed via Asia Minor by the Tartar armies of Khan Janibeg. They had laid siege to the city of Kaffa. It is a Genoese trading city on the shores of the Black Sea. The siege of the Tartars was unprofitable. Before they left, they received a description by Gabriel de Mussis from Piacenza.
In vengeance they pelted over the walls of Kaffa carcasses of people gave out from the Black Death. In fear the Genoese dealers fled in galleys with sickness sticking to their bones to Constantinople and across the Mediterranean to Messina, Sicily, where the great epidemic of Europe started. So, it reached Paris, Marseille, and Germany by 1348. It also reached Spain in 1349, and eastern Europe in 1350.
American plague pandemic
The American Plagues were a clump of Eurasian illnesses. The European explorers brought these illnesses to America. These diseases contained smallpox amongst others. All these contributed to the exhaustion of the Inca and Aztec societies. So, this caused the death of about 90 percent of people in the Western Hemisphere. These illnesses helped a Spanish force to conquer the Aztec capital of Tenochtitlán in 1519. Hernan Cortes led the army of soldiers. Francisco Pizarro led another Spanish force that conquered the Incas in 1532. People from other European countries started conquering and settling in the American continent. They received help from the fact that illness had extensively reduced the size of any indigenous groups that opposed them.
Philadelphia yellow fever
When yellow fever seized Philadelphia, the United States capital at the time, officers incorrectly believed that slaves are immune from this. After these abolitionists called for African-origin people for nurse recruitment. The illness is carried and transmitted by mosquitoes, which sustained a population bang during the particularly hot and sticky summer weather in Philadelphia that year. It was not until winter arrived — and the mosquitoes died out — that the epidemic stopped. By then, more than people had died.
The plague destroyed Moscow. Riots spread through the city and were crowned in the murder of Archbishop Ambrosius, who was encouraging crowds not to gather for idolization. So, the empress of Russia was Catherine II (also called Catherine the Great). She was very hopeless to contain the plague and restore public order. For this, she issued a hasty decree ordering all plants to move from Moscow. By the time the plague ended, as many as 90 percent of people may have died. In 1773, Yemelyan Pugachev, a man who claimed to be Peter III (Catherine’s executed husband), led an insurgency that resulted in the deaths of thousands more.
Influenza pandemic took place in 1918 – 19. It is also known as Spanish influenza pandemic or Spanish flu. It is the most severe influenza outbreak of the 20th century. In terms of total figures of deaths, it is among the most destructive epidemics in human history. Influenza is caused by a contagion that is transmitted from person to person through airborne respiratory secretions. An outbreak can come about if a new strain of influenza contagion emerges against which the population has no immunity. Thus, the influenza pandemic of 1918 – 19 panned out from a drastic circumstance. It affected populations throughout the world.
The influenza contagion is called influenza type A. Its subtype is H1N1. This panned out in an estimated 25 million deaths. However, some experimenters have projected that it caused as many as 40 – 50 million deaths.
The 1918 influenza epidemic was the most severe epidemic in recent history. The H1N1 contagion with genes of avian origin casues influenza. Although there is not universal agreement regarding where the contagion began, it spread worldwide during 1918-1919. In the United States, it was first linked in military help in spring 1918. Mortality was high in people younger than 5 years old, 20-40 years old, and 65 years and aged.
The mortality rate is high in healthy people. It also includes those in the 20–40-year age group. It was a unique point of this epidemic. There are no vaccines to cover against influenza infection. Also, there are no antibiotics to treat secondary bacterial infections. We associate these infections with influenza infections. Control efforts worldwide not more than non-pharmaceutical interventions. These include isolation, confinement, good subjective hygiene, use of cleansers, and limitations of public gatherings. Unfortunately, we did not apply these equally.
What are we learning? The most recent COVID-19 pandemic.
So, history has seen multiple epidemics emerge and conclude, with medical and scientific understanding, living conditions, and socio-political contexts all playing a part in the association, control and stopping of an epidemic. The illnesses themselves also separate epidemics from each other, as some contagions or bacterial infections bring about more severe symptoms and affect different populations, who may be more vulnerable than others. For example, COVID-19 altogether causes severe symptoms in people over 65 and those with underpinning health conditions, whereas the 1918 influenza caused severe symptoms in young and healthy populations. Therefore, reporting certified cases precisely and feeding accessible testing are particularly helpful manners in understanding an evolving pandemic like COVID-19.
