Before the advent of the Corona virus there has been some diseases that have taken the lives of many people in human history and are still even in existence till this day like Cholera, small pox, bubonic plague, HIV/AIDS and so on.
Some key concepts to note;
Bacteria: are microscopic single-celled organisms that thrive in diverse environments like Soil, Ocean, Human gut and so on.
Virus: is a microscopic parasite that can infect living organisms and cause diseases.
Flu: also called Influenza, is a respiratory illness that results from a viral infection.
Epidemic: is a disease affecting many persons at the same time and spreading from person to person in a locality where the disease is not permanently prevalent. It covers only a particular region or community.
Pandemic: is a disease prevalent over a high population, continent or the entire world.
Below are the deadliest pandemics in the world since the 20th century.
The swine flu which originated from Mexico in 2009, before spreading to the rest of the world infected 21% of the world’s population and killed over 500,000 people.
Surprisingly, the virus killed younger people (below 65) rather than the aged population (65 and above), this was quite unusual because most virus and flu pandemics claimed the lives of the aged population but not in the case of Swine flu.
THE HONG KONG FLU

The virus killed over a million people including 500,000 from Hong Kong.
The virus which lasted for 2 years originated from the Chinese province of Guizhou before moving to other parts of Asia and the united states. The Asian flu like the Spanish flu was believed to have originated in birds, it spread from east Asia to the rest of the world.
Reports from the world health organization reveals the virus claimed approximately 2 million lives.
This is an highly infectious bacteria transmitted via faeces, contaminated water and so on. Reports from the world health organization reveals that there are 1.3 million to 4.0 million cases yearly and 21,000 to 143,000 deaths worldwide. There has also been seven Cholera pandemics in history which claimed multiple lives.

The seventh Cholera pandemic between 1961-1975, which was more rampant in Asia and North Africa.
The 1918 flu though sometimes called the Spanish flu, not because it originated in Spain but because of its eminence in World war I and Spain was the only country being honest about the pandemic rise reports. It was believed to have originated in birds and it infected one third of the world’s population.
