Covid-19 Pandemic | Easy History of World’s Pandemics

Covid-19 Pandemic

The rampant spread of disease among species is prevalent worldwide, just like the Covid-19 pandemic. The same applies to diseases spreading within human populations in significant proportions. The range of conditions limited to multiple cities of the same country is called an epidemic for that particular area. Once such a disease spreads to the towns outside of a single country, it is into multiple states. Even continents refer to as a pandemic.

Pandemics kill hundreds of thousands of people who can go up to millions of casualties if the actions were not taken to contain the disease. Throughout human history, as more and more people started forming larger colonies and countries began to grow and conquer lands, the conditions also spread, and many developed into pandemics.

In the documented human history, the following are the most widespread diseases that took the communities of that time by storm:

 

Plague of Athens (430 BC) | History of Pandemics

This plague spread as the war raged between the cities of Athens and Sparta. This plague affected an enormous number of people in total and killed over a hundred thousand. The symptoms included sudden redness, heats in the head, inflamed eyes, throat, and tongue, causing bloody appearance and fetid breath. The exact source of the disease is yet to be known.

Plague of Justinian (543 AD) | History of Pandemics

It is one of the first accounts of the spread of bubonic plague among human communities. The disease spreads through flea bites that were found in small animals like rodents. Once the pathogen enters the lungs, it causes high fever followed by fatigue and swollen lymph nodes. When this plague hit the Byzantine Empire, it is said to have killed over 10% of the world’s population at that time as the spread of disease from human to human is exponential.

The Black Death (1346-1353) Pandemic

It was another instance in human history when the bubonic plague ravaged the human population. The disease spread from Asia and into Europe. The organism found to be responsible is a bacteria called Yersinia pestis, which resides in the lungs. The victims are bury in mass graves, usually built outside the cities to stop the spread.

Spanish flu epidemic (1918-1920) pandemic

This flu-like disease infected over 500 million people and caused 100 million of them to die from it. It spread throughout the globe, from South Seas reaching far and wide to the North Pole. During World War 1, the cramped up conditions of the soldiers aided in the spread even more. The disease, however, did not start in Spain.

H1N1 (Swine flu) spread 2009 pandemic

It started in Mexico in 2009 and spread throughout the world by 2010. In a single year, over 1.4 billion people were found infected with it, and about 575,400 people had died. The disease is like the flu that proceeds to become lethal for children with lower immunity.

Covid-19 pandemic (2020) | Coronavirus pandemic 

In late December of 2019, in a Chinese city of Wuhan, the virus named SARSCov-2 emerged. Covid-19 declared an epidemic within months, and by March 2020, the WHO has declared it a world health emergency and a pandemic.

The disease causes flu-like symptoms, and with people of lowered immunity, like the elderly, it can rapidly develop into life-threatening ARDS. Until the present day, no definite cure or vaccine produce against the Covid-19 pandemic.
