Why are more deadly epidemics likely to occur in the future?

We’ve been trying to deal with the coronavirus epidemic around the world for the last two years. The epidemic started in Wuhan, China and spread around the world, but it’s not the first epidemic in the world. This is the last plague – epidemics have always been part of human history.

Why do epidemics spread?

To find the answer to this question, we need to understand the evolutionary processes and attitudes of human societies. Man has been in this world for about 300,000 years now. Lived in the form of and these tribes had very little contact with other tribes – so if an epidemic spread in one tribe, it was limited to the people of that tribe, did not spread to other tribes.

Ten thousand years ago today, human societies began to change – humans invented agriculture and thus people began to cultivate in the most fertile areas of the world, villages began to change into towns and cities began to change into cities – man began to raise animals and Humans and pets (cattle, horses, donkeys, cats, dogs, chickens, etc.) began to live together – these animals had many viruses against which the animals had a natural defense, but these viruses were new to humans. Humans did not have any resistance to these viruses. In this environment, many viruses began to be transmitted from animals to humans, and thus epidemics began.

Are epidemics on the rise?

Today the situation is that we farm animals for our food on an industrial level where millions of animals are kept together on extremely tight leashes – in this environment, if a virus mutates in an animal and becomes dangerous, very fast. Can spread to entire animal populations

At present, 70% of the world’s bird population is farm-raised chickens raised by humans on poultry farms – 60% of the world’s mammals are farmed cattle that are raised by humans – these animals have become factories of mutations for the virus which gives rise to many new epidemics.

Due to the continuous increase in human population, the area of ​​cities is increasing and in order to produce food for this population, forests are being cut down and the land is being made cultivable. Today, 47 of the world’s arid regions. The percentage is in human consumption – this is why humans and wild animals that used to be completely isolated from each other are now facing each other and viruses in wild animals are also spreading in humans and the number of epidemics is increasing.

Are epidemics spreading faster now?

Due to the invention of agriculture about six to seven thousand years ago today the world’s population began to grow, cities began to become dense, people from far and wide began to settle in cities and viruses in remote areas carried with them.

Began to be brought to the cities – trade caravans began to move from one country to another, which led to the rapid spread of viruses – after the Industrial Revolution, the population of cities began to grow rapidly and at the same time the number of diseases began to increase. Today the world’s population has reached eight billion. The more dense the population of any city, the more easily epidemics will spread in that city.

Due to industrial development transportation has also improved and people from far flung areas have started moving to big cities. Traveling has become easier. Gone are the days when the armies of one country began to occupy another in wars. Because of all that, viruses from far-flung areas that once made people in that area sick could now spread all over the world. Therefore, the risk of future epidemics is increasing.

Can Modern Medical Technology Prevent Outbreaks?

Modern medical science has also learned to control many epidemics – man has learned from experience that the spread of epidemics can be prevented if sick people are immediately isolated from the rest of the population – germs in 1861 Discovered and found to be the cause of many diseases.

In the 19th century, sewage systems began to be installed in major cities so that dirt and grime could no longer be spread on the streets. Vaccines for deadly diseases became available – these vaccines led to a sharp decline in deaths from infectious diseases worldwide and a rapid increase in the average life expectancy.

In the 21st century, modern technology has enabled us to eradicate the next epidemic before it spreads. Resistance exists – with the help of genetic engineering, a vaccine against the virus was

invented within a few months and half the world’s population was vaccinated in one year – due to the rapid spread of the coronavirus. Chances are low and life around the world is back to normal.

With this technology, the vaccine against any future outbreak will be ready in a few weeks, so it is now possible that the next outbreak will not spread so fast.
