Throughout the 2010s global pandemics have occurred more and more often than ever before. With diseases like Ebola, SARS, Zika, and now Covid-19, it has become clearer that there are specific reasons why epidemics are more and more common in recent years. The CoronaVirus pandemic was for sure unexpected, but was it really surprising when looking at recent history? With factors like increasing world population and health worker shortages, the world has become more susceptible to global pandemics.
Of course one of the biggest reasons for the recent rise in diseases is due to world population. It makes sense, as more people means more victims for the bacteria and viruses to feast on. According to gavi.org, the UN predicts by 2050, 66% of the world will be urbanized. This is a huge jump from 70 years ago, where 66% of the world lived in rural communities. As cities and countries build more infrastructure, housing, and better sanitation, a greater number of people will be attracted to start families in these urban areas. As these urban areas continue to grow in size, diseases also spread in greater numbers, even with the better sanitation systems in place. Further urbanization correlates with health-care worker shortages, another major factor contributing to the rise of pandemics in the recent past.
According to ined.fr, over 258 million people worldwide do not live in the world they were born in. That number continues to increase, an approximate 2.4% increase a year. This means that about 3.4% of the world’s people are immigrants, and this number will continue to rise as the population increases as well. Constant immigration to countries creates trouble for health care workers as they have to deal with new influx of people who may carry disease from their home country. According to mphdegree.edu, the threshold for health care workers is 23 per 100 people, and as of now 83 countries still fail to reach that number. Due to the increase of immigrants, countries are unprepared to supply the right amount of health-care workers, as their population grows significantly in a short period of time. Without the proper amount of health care workers to take care of patients, a pandemic will only continue to get worse, as many patients will not receive proper treatment.
As one can see, pandemics such as the CoronaVirus will not disappear from out lives forever. With the massive growth of the human population and the scarcity of health-care workers, the world will not cease to see devastating diseases from wreaking havoc on civilization. Hoping and praying for the health and safety of our people will not be enough. If no action is taken towards creating more efficient and safer health standards, the human population will be at grave danger. There is hope however, as technology and medical studies continue to advance, the health and wellbeing of the world’s citizens are a top priority.
