Nature is a complex structure made up of living and inanimate beings. Life is established, continues and ends with the interaction of living structures in nature with each other and especially with their environment. Viruses that occur in structures such as polyhedral, rodlike, filamentous, and are usually 20-200 mm in size are also a part of this interaction (Figueroa, Fleischmann, & Goepferich, 2021). However, it is known that some types of viruses pose a significant danger, especially to humans, and said danger can intensify with mutations that they go through over time (Payne, 2017).
For humans, this condition is experienced in the form of human-to-human or animal-to-human transmission, and can be observed in many different examples such as influenza, HIV, and viruses belonging to the coronavirus family. If the virus has a biologically negative effect on a group of people, the situation is called an epidemic; if it affects almost all people or other living things in that group, it is called a epidemic(Cambrigde Dictionary, 2021).
Epidemics that can be explained in this way have from time to time in human history caused biopsychosocial destruction in social and individual terms, especially on health and management systems. The first example that comes to mind on this issue is the Black Plague. Seen in Asia, Europe and Africa in the 14th century, and thought to be caused by the virus named Yersinis Pestis today, the plague has caused the deaths of millions of people all over the world;so much so that today it is estimated that the disease resulted in the death of at least 30% of the European population (Raoult, Mouffok, Bitam, Piarroux, & Drancourt, 2013). On the basis of it being widespread, plague has led to various social transformations. Here, in particular, it has been noted that a serious decrease in the labor supply increased labor costs, and feudal structures began to lose their power in the process of centralization (Ceylan, Ozkan, & Mulazimogullari, 2020). In addition, this unusual decrease in labor supply led to technological developments and their spread through labor mobility (Harris & Moss, 2020).
Another large-scale epidemic in history is the Spanish Flu, which occurred between 1918 and 1919. It is estimated that 500 million people were infected with the Spanish Flu, and that close to 50 million people, which is 1-3% of the world's population, died. (Encyclopaedia Britannica, 2020; Patterson, Mclntyre, Clough, & Rushton, 2021). The greatest impact of the Spanish Flu, which spread rapidly with the impact of World War I, was impoverishment. According to Barro et al., there was a 6% decrease in national income per capita, and 8% decrease in consumption expenditures due to the Spanish Flu (Ceylan, Ozkan, & Mulazimogullari, 2020). In addition to its general economic effects, Spanish Flu has also had an impact on economic inequality in society. In Italy, for example, Spanish Flu led to a 2% increase in income inequality (Galetta & Giommoni, 2020). In Sweden, it is estimated that every death caused by Spanish Flu led to impoverishment of four people (Karlsson, Nilsson, & Pichler, 2014). In addition to the plague and Spanish Flu, it is known that a type of plague experienced between 541-543, and epidemics caused by viruses such as SARS, MERS, H1N1 experienced at the beginning of the 21st century have also had negative socioeconomic and sociocultural effects(Piret & Boivin, 2021).
Without a doubt, it is possible to add the ongoing epidemic to these experiences. Having first occurred in December 2019 in Wuhan, China, and announced by the World Health Organization on March 11, 2020, as a epidemic, the SARS-CoV-2 virus has already affected humanity extraordinarily in different ways (World Health Organization, 2021). It is estimated that this virus is approximately 80-120 mm in diameter and has thirty thousand RNA helices, and is transmitted from bats or pangolins to humans (Das, Das, & Ghangrekar, 2020).
SARS-CoV-2, which is believed to be transmitted directly from animals through an intermediate host animal, or through cold chain products, is a virus belonging to the coronavirus family and has a genome similar to other coronaviruses by 79%, and to MERS by 50%(World Health Organization, 2021). But despite this genetic similarity, as can be seen in Figure 1, the SARS-CoV-2 virus ranks only the second to last among viruses in the last 50 years in terms of fatality.
It is known that up to 50% of SARS-CoV-2 infections, also known publicly as COVID-19, can be asymptomatic and have different consequences on people who are infected, from mild symptoms to death (Piret & Boivin, 2021; Binns, Low, & Kyung, 2020). The most common symptoms of SARS-CoV-2, which can be listed as fever, dry cough, shortness of breath, fatigue, headache, and weakness, have very harmful effects, especially on the respiratory system and immune system(Das, Das, & Ghangrekar, 2020).It is known that the SARS-CoV-2 epidemic is especially dangerous for individuals over 65 years of age and people with chronic illnesses; the epidemic is also affected by the internal and external mobility of countries, as well as the prevalence of testing and detection studies(Velasco, Tseng, & Chang, 2021).
Unlike the SARS-CoV virus that emerged in 2003, the symptoms of SARS-Cov-2 surface within a few days of the onset of inter-human viral transmission, which was one of the biggest factors in the transformation of SARS-Cov-2 into a epidemic (Piret & Boivin, 2021). In addition, the fact that the first symptoms of SARS-CoV-2 are quite similar to cold and influenza also affects this situation (Binns, Low, & Kyung, 2020). Naturally, the growth of globalization and the resulting mobility of human and commercial animals can also be considered as another important factor in the transformation of the virus into a epidemic. Another study conducted using data from 360 different cities showed a positive relationship between the national income per capita and geographical latitude, and the number of COVID-19 cases; meanwhile the number of cases has a negative relationship with temperature. This also shows that a global epidemic is actually shaped by various local factors (Cao, et al., 2021).
The biological structure and developmental process of the COVID-19 epidemics caused by the SARS-CoV-2 virus can be explained in this way. According to World Health Organization data, a total of 200,840,180 cases were reported worldwide as of 07.08.2021, of which 4,265,903 resulted in deaths. When the distribution of cases and deaths per hundred thousand people is examined, especially the United States, Russia, Canada, South American countries, and European countries rank the highest (World Health Organization, 2021).
Data from the World Health Organization proves that the COVID-19 epidemics have reached a fairly significant magnitude. But a epidemic, due to its factual nature, is not just a condition that causes biological damage. As in previous epidemics, the COVID-19 has involved various socioeconomic damages. A study conducted by Figueiredo et al. (2021) showed that social isolation in childhood increases the risk of infection, obesity, depression and loneliness in later years, noting that quarantine processes especially in developing countries negatively affect income inequality and domestic relationships (Figueiredo, et al., 2021). Robb et al. (2020) have found a positive relationship between quarantine and anxiety (Robb, et al., 2020). Gonçalves et al. (2020) concluded in their study that mental well-being is negatively associated with social isolation and loneliness (Gonçalves, et al., 2020). According to UN Women, the psychosocial and socioeconomic conditions caused by the epidemic increased gender inequality and, in particular, increased domestic violence (United Nations Entity for Gender Equality and the Empowerment of Women, 2020). Another effect caused by the epidemic is the change in criminal activity. A study conducted by Stickle and Felson (2020) examined the relationship of the epidemic with criminal activities and revealed that this relationship depends on the variables of type, place, and time of crime. These findings show that the epidemic-crime relationship is changeable but can pose social hazards according to the local characteristic of the epidemic (Stickle & Felson, 2020).Pietrabissa and Simpson (2020) claimed that the next epidemic will be the ‘depression epidemic’, referring to many studies that examined the negative effects of social isolation and loneliness (Pietrabissa & Simpson, 2020). In addition to the psychosocial effects of the epidemic, some studies state that there is a negative relationship between the inactive lifestyle caused by quarantine restrictions, and biological health (the heart above all else) and a regulated life (sleep, nutrition, etc.) brought by social isolation(Peçanha, Goessler, Roschel, & Gualano, 2020; Hwang, Rabheru, Peisah, Reichman, & Ikeda, 2020).
In addition to the social and biological effects, the epidemic has important economic effects. Shang et al. (2021) revealed that COVID-19 has been the most destructive epidemic of the 21st century in the sense of unemployment rates, inflation and investments, and supply chains (Shang, Li, & Zhang, 2021). In addition, according to the International Monetary Fund (IMF), the world economy experienced a 3.5% contraction in 2020 in terms of real gross domestic product values (International Monetary Found, 2021). According to the International Labor Organization (ILO), industrial production in the G-20 countries has decreased by up to 60% as of February 2020 compared to the previous period. According to the same report, there has been 14% reduction in total paid working hours in the aforementioned countries. In addition, due to the epidemic, unemployment rates in these countries has increased by more than 10% (International Labour Organization, 2020). As can be seen from these statistics, the destruction caused by the epidemic has reached such a serious extent that an assessment shared by the World Health Organization in October 2020 predicts that the number of malnourished people will increase from 690 million to 822 million in 2020 alone due to the recession occurring in the economy (World Health Organization, 2020).
Several measures have been developed against the ongoing destructive effects of the COVID-19. Some methods developed to treat infected people can be listed as natural cell therapy, immunotherapy, and various drug supplements used to treat diseases such as malaria (Das, Das, & Ghangrekar, 2020). Furthermore, vaccine development efforts have been continuing from the beginning, and as of 07.08.2021, 3,984,596,440 doses of vaccine have been administered worldwide (World Health Organization, 2021). Moreover, 96 vaccine studies are in clinical development, while184 vaccine studies are in pre-clinical development, according to World Health Organization data from August 2021(World Health Organization, 2021).
In addition to measures for the treatment and prevention of disease, full or partial quarantine measures such as the closure of the facilities outdoors that are not vital, the closure of schools, limiting hours of work and transition to flexible working hours, cancellation of events that are not urgent, emphasizing personal hygiene and social distancing have also been developed(University of Oxford and Blavatnik School of Goverment, 2021). In addition, according to the IMF, as of October 2020, the worldwide epidemic support offered includes $9,930 billion for additional payments or waived revenues, and $6,104 billion for liquidity support(International Monetary Found, 2021). The dynamics of the epidemic that interrupt the natural flow of social life suggest that epidemic management should also be evaluated in a multidimensional and interactive framework.
