  • The Korean government’s strategy to combat coronavirus disease 2019 (COVID-19) has focused on non-pharmaceutical interventions, such as social distancing and wearing masks, along with testing, tracing, and treatment; overall, its performance has been relatively good compared to that of many other countries heavily affected by COVID-19. However, little attention has been paid to health equity in measures to control the COVID-19 pandemic. The study aimed to examine the unequal impacts of COVID-19 across socioeconomic groups and to suggest potential solutions to tackle these inequalities. The pathways linking social determinants and health could be entry points to tackle the unequal consequences of this public health emergency. It is crucial for infectious disease policy to consider social determinants of health including poor housing, precarious working conditions, disrupted healthcare services, and suspension of social services. Moreover, the high levels of uncertainty and complexity inherent in this public health emergency, as well as the health and socioeconomic inequalities caused by the pandemic, underscore the need for good governance other than top-down measures by the government. We emphasize that a people-centered perspective is a key approach during the pandemic era. Mutual trust between the state and civil society, strong accountability of the government, and civic participation are essential components of cooperative disaster governance.
During the coronavirus disease 2019 (COVID-19) pandemic, many global leaders and celebrities contracted COVID-19. These high-profile cases contributed to the widespread idea that the virus universally attacks people without any discrimination. This claim is not new, as the contention that “the flu hit the rich and the poor alike” was widely accepted during the Spanish flu epidemic of 1918 [1]. However, the incidence and mortality of Spanish flu were unequally distributed by socioeconomic position. Similar patterns of health inequity have been repeatedly observed for various infectious diseases such as tuberculosis and human immunodeficiency virus [2,3]. Although the differential impact of COVID-19 pandemic on disadvantaged populations has been reported worldwide [4,5], this issue has received relatively little attention from researchers in Korea. A few studies have identified inequalities in the incidence and mortality of COVID-19 across income groups, but the their focus was not to examine the unequal effects of the pandemic [6,7].
The Korean government’s strategy to combat COVID-19 has focused on testing, tracing, and treatment, along with non-pharmaceutical interventions such as social distancing and wearing masks, and its performance has been relatively good compared to that of many other countries heavily affected by COVID-19. However, little attention has been paid to socioeconomic inequalities, and the value of alleviating these inequalities has not been clearly recognized as a way to control the pandemic.
During the early phase of the pandemic, we conducted a study to interpret the pandemic situation from a people-centered perspective. The study team reviewed published and unpublished papers, and interviewed vulnerable populations including homeless people, immigrant workers, the disabled, healthcare workers, and precarious workers. We released a report titled the “People’s Report on the COVID-19 Pandemic in South Korea” [8]. This review was conducted to restructure a part of the report with the aims of examining the unequal impacts of COVID-19 across socioeconomic groups and suggesting potential solutions to tackle these inequalities.
Conceptual Framework
The COVID-19 pandemic could have unequal health and social consequences across socioeconomic groups, both directly [5] and indirectly [9]. Figure 1 depicts a conceptual framework for the direct and indirect impacts of COVID-19, with potential mechanisms linking socioeconomic position and health. The holistic framework spanning from distal determinants to proximate risk factors for health developed by the Commission on Social Determinants of Health [10] presumes that political, economic, and environmental policies could affect various social determinants of health and subsequently, influence health outcomes. These mechanisms could be used to identify entry points for interventions to mitigate the direct impact of COVID-19 on health inequity. For instance, comorbidities affected by social determinants could diminish the function of the immune system and provide a fertile ground for contracting COVID-19 and having a poor prognosis. Social determinants could directly influence COVID-19 infection and its consequences regardless of individuals’ comorbidities. Moreover, strong mitigation measures such as lockdowns and closure of workplaces and schools could contribute to unemployment, income loss, mental health deterioration, child abuse, and gender violence [11]. These negative impacts are not equally distributed; instead, they disproportionately accumulate among disadvantaged populations, including precarious workers. Delayed or disrupted healthcare utilization, which is driven by the fact that the public healthcare system is solely committed to dealing with the COVID-19 pandemic, is also a crucial social determinant of health. Based on this conceptual framework, this study examined the extent of our knowledge of the direct and indirect impacts of COVID-19 from empirical studies and elaborated upon the role of social determinants in Korea.
Several studies have found associations between income level and COVID-19 morbidity and mortality in Korea. In a cohort of patients with hypertension, COVID-19 incidence was higher in the low-income group than in the higher-income group [7]. An observational study analyzing the data of approximately 9000 COVID-19 patients from the National Health Insurance Service identified higher COVID-19 mortality in the low-income group than in the highest-income group [6]. Other studies have reported that comorbidities had negative effects on COVID-19 mortality [12,13]. Based on those findings, although those studies did not aim to identify heath inequities, we would argue that the direct impact of social determinants has been partially verified. Few studies have focused on the indirect impacts of COVID-19 in Korea. One United Kingdom study found higher all-cause mortality among marginalized populations, compared with those in preceding years [10]. Although inequalities in all-cause mortality during the COVID-19 pandemic in Korea have not been verified, a study provided partial evidence for the negative impact of the curtailment of essential healthcare services. Specifically, researchers found that the tuberculosis notification rate in Korea had declined during the COVID-19 pandemic compared to the previous 5 years in Korea [14].
The direct impacts of COVID-19 pandemic on health inequity involve an unequal risk of infection and its health consequences. Living conditions are among the most important social determinants. Populations excluded from mainstream society, including migrant workers, the disabled living in facilities, and homeless individuals, have faced being socially distanced and marginalized even before the pandemic, and ironically their condition of being “distanced” was considered as a safeguard against virus transmission. The reality is that their living spaces are very cramped, and they must involuntarily share common spaces such as toilets and kitchens. Accordingly, a single case of infection could bring devastating consequences in the community, as shown in the outbreak in a long-term care hospital in Cheongdo, where 103 patients were infected and 8 patients died of COVID-19 [15]. The building design and methods of patient care facilitated the spread of the virus, and cohort isolation without appropriate protection measures resulted in this disastrous event [16].
Crowded workplaces are another favorable environment for the spread of COVID-19, and a series of outbreaks have occurred in call centers and warehouses. Those workplaces were very crowded and proper distancing between workers was impossible [17,18]. Protective measures such as a ventilation system, masks, and hand-washing facilities were limited as well [19]. Moreover, precarious workers are hardly in a position to demand appropriate measures for infection prevention due to the power imbalance between them and their employers [20]. This power relationship is closely related to vulnerable working conditions and employment status, which subsequently impose a double burden on workers [21].
One of the important pathways through which COVID-19 exerts indirect effects on health inequity is disrupted healthcare utilization. Disadvantaged populations such as undocumented immigrants and homeless people usually visit public hospitals, but all public hospitals were designated as COVID-19 treatment centers and minimized their usual medical services. Meanwhile, private hospitals, although they are not-for-profit entities and are mainly funded by the National Health Insurance Services, often refuse to treat patients with mild respiratory symptoms or signs [22].
In addition to medical services, the provision of social services was limited to prevent virus transmission. The central government announced a recommendation to close community centers for welfare services on February 28, 2020, and accordingly, about 99% of 111 101 centers were shut down until April [23]. The disabled were temporarily unable to access rehabilitation services and homeless people had to skip their meals because of the closure of free meal services [24].
By reinforcing the existing social inequity, the negative impacts of the COVID-19 pandemic on health have been aggravated. COVID-19 is literally a “systemic pandemic of inequity” [9].
People-centered Perspective
In recent years, the notion of a “people-centered perspective” has emerged in various fields as a critique of state power, market power, and expert-centeredness. In the public health field, “people-centered” means that care and management are organized around the health needs and expectations of people rather than diseases and providers’ perspectives [25,26]. The response to COVID-19 in Korea was closer to an administrative-centered perspective than a people-centered perspective. Closure of public spaces enabled the public authorities to avoid responsibility for possible outbreaks in the spaces under their control, without considering the suffering and needs of people affected by the abrupt suspension of services. This led to unequal impacts, as shown in Figure 2. For a public health emergency response from a people-centered perspective, we need to ask what people can do, what people want to do in their daily lives, and who people engage in those activities with. We should make efforts to identify people’s competencies and provide the necessary support for sustaining their life [27]. Good governance and civic participation are the main strategies to achieve this goal, and a people-centered perspective should be both a principle and an way of approach.
Good Governance and Civic Participation
The policy measures to respond the COVID-19 pandemic include socioeconomic interventions beyond public health policies. To minimize the human suffering caused by the both the social and health impacts of the pandemic, “democratic publicness” in the multilayered social system is important. This framework can alleviate the harmful effects of the pandemic, by enabling people to participate in the decision-making process and its practices. There is a high-level of uncertainty in public health emergencies such as pandemics, and the government alone cannot manage and control these unprecedented risks. The government and civil society have limited information and knowledge. Most solutions are provisional and are likely to be revised as new scientific evidence is obtained. Accordingly, it is crucial to establish a relationship of mutual trust between the government, experts and citizens. It is for this reason that we have emphasized the need for “cooperative disaster governance” based on collective intelligence from the diverse experiences of different stakeholders [28].
This unprecedented pandemic has allowed the government to restrict the liberty of the citizens to protect them and the wider public from infection. Such measures are indispensable to some extent, but are often followed by unequal distribution of the risk and infringement of human rights. The meaningful participation of civil society in decision-making at various levels is essential to monitor the government and reinforce their accountability to the people more than ever. The economists Bowles and Carlin [29] suggested that the civil society could provide an essential strategy to overcome the pandemic through pursuing public virtue and willingness to cooperate with government, promoting trust in the public health measures recommended by government, and practicing ethical values such as fairness, sustainability, and reciprocity.
To establish cooperative disaster governance during this public health emergency, we would like to suggest the following core components. First, cooperative governance should aim to realize social values including fairness, transparency, and equity. This public health emergency is a form of harm at a society-wide scale, and therefore should be recognized as a common task between the state and civil society.
Second, cooperative governance does not imply shifting accountability from the government to civil society. In most situations, the state is the only polity with the physical power and economic resources to deal with the enormous and complex problems encountered during a disaster [30]. The government should recognize its accountability more as part of cooperative governance.
Third, the government should establish channels to communicate and cooperate with various civil society organizations, and support communities to organize themselves.
Fourth, risk perceptions are important to consider for promoting protective behaviors by individuals, and efforts to encourage appropriate risk perceptions should be made during the COVID-19 pandemic, as non-pharmaceutical interventions based on voluntary cooperation of people are the only available measures to combat the spread of COVID-19 [31]. The risk communication of the government should be focused on the following 6 values: “be first,” “be right,” “be credible,” “express empathy,” “promote action,” and “show respect” [32].
Finally, decentralized governance should be institutionalized to procure public health resources and allow citizens to participate in actions within the local context. The global pandemic has served as an opportunity to recognize the importance of local responses; the risk and damage have not been equally distributed across regions, and communities with fewer resources have been more likely to be hit by the pandemic itself and affected by its consequences.
Based on a review of the existing literature, we constructed a conceptual framework to depict the direct and indirect impacts of COVID-19 on health and social inequalities. The pathways linking social determinants and health could be entry points to tackle the unequal consequences of this public health emergency. Poor housing, precarious working conditions, disruptions of healthcare services, and suspension of social services are relevant examples of social determinants.
The COVID-19 pandemic and responses to the pandemic have resulted in the unequal distribution of risk and burden across regions and social groups. The high-levels of uncertainty and complexity inherent in this public health emergency, as well as the health and socioeconomic inequalities caused by the pandemic, underscore the need for good governance other than top-down measures by the government. Mutual trust between the state and civil society, strong accountability of the government, and civic participation are essential components of cooperative governance.
The COVID-19 pandemic will not be the last public health emergency for the human race. If we learn lessons from the COVID-19 pandemic and engage in preparedness planning based on these lessons, we may be able to respond fairly and equitably to future public health emergencies.
