Impact of COVID-19 health crisis on health systems of countries; an evaluation with the dimension of global health systems

The countries' unpreparedness in managing the COVID-19 epidemic and the inadequacies of the global health system have turned the outbreak into a worldwide health crisis. In this study, the impact of the COVID-19 health crisis on the health systems of countries was evaluated based on the literature in terms of global health systems. Unlike other epidemics, the coronavirus has spread rapidly in all countries, regardless of income. The United Nations and the World Health Organization (WHO) stated that a joint approach is necessary for supporting global solidarity policies so that the COVID-19 process due to social, economic, and health inequalities between countries does not get worse. However, it has been seen that the disagreements between some powerful countries that are influential in global politics negatively affect the global health system and epidemic management. With the onset of the COVID-19 epidemic, some countries brought the "my nation first" approach to the fore, undermining the fair implementation of global health policies. The member countries of the World Trade Organization have also violated the trade agreements made and imposed export restrictions on the products necessary for the fight against the epidemic. It has also been reported that high-income countries disregarded public health and human rights approaches during the epidemic and reached COVID-19 vaccines proportional to their purchasing power. It has been observed that the epidemic cannot be managed effectively at the global level, although the global health system is more needed throughout the world during the pandemic process. It was emphasized that redesign is necessary for effective governance of the global health system.
