As an epidemic that emerged in China in the last month of 2019 and caused political, social and economic changes at the international level in a very short time, the Covid19 pandemic started a period of isolation in social life and created a new process in which countries closed their borders politically. The epidemic, seen as a security threat by political authorities around the world, is considered as a new turning point in the transformation of security after the Cold War and September 11.

 In the article, the interventionist attitude on the implementation of curfews, restriction of entry and exit to the country, and tightening of controls during the continuation of the struggle under the conditions that emerged with the increase of the epidemic is analyzed on the basis of securitization. Threat perceptions in the pandemic period in which the role of the armed forces and the security understanding of the state are redefined, are evaluated as a result of extraordinary conditions and uncertainty. In today's world where restrictions are imposed by the state in every aspect of daily life, the gradual tightening of the security circle naturally brings along an isolationist process for individuals and states in social and political terms.
