The phenomenon of human security aims to combine security with human rights and freedoms as a product of the changing security perception of the West after the Cold War. The concept of human security has transformed security from the perception of “only the absence of threat” to a perception in which elements such as “fears and needs” are also taken into account. However, the new circumstance affected by COVID-19 and the measures taken to combat the pandemic have enforced us to experience a period in which human security is eroded, anxiety becomes the dominant emotion, dif􀏐iculties arise in meeting the existing needs as well as the new needs that are dif􀏐icult to meet. During the COVID-19 pandemic, the concept of human security has been abandoned and the classical protective-restrictive security approach has been adopted due to the wideness of the concept and its dif􀏐icult nature to de􀏐ine, which has criticised many times. In this process, sources such as the hierarchy of rights, the sociality of responsibility and the limit of freedom have constituted the legitimacy of the restrictive measures that had been taken. These extraordinary conditions, which are deemed appropriate for the limitation of rights and freedoms, are listed as a legitimate reason for the limitation of freedom in many legal texts. Another point that provides the legitimacy of struggle in extraordinary situations such as epidemic is the rarity of such cases. However, the world is faced with a problem that will destroy this source of legitimacy. While the world is changing rapidly, viruses that cause epidemics are not at a 􀏐ixed point. The rapid evolution of viruses and the spread of epidemics indicate the possibility of similar the outbreaks like the COVID-19 pandemic in the near future. For this reason, it will not be suf􀏐icient for concepts such as human security to be damaged in such extraordinary situations and to be amended again in the subsequent normalization processes. This study aims to analyze the human security phenomenon, the erosion that it has experienced during the COVID-19 pandemic, its underlying sources of legitimacy and the possible problems to be encountered.
