This study aims to identify the health security threats in terms of infectious diseases, and the problems brought by COVID-19 and the response by the military. This study established health security concepts in the non-traditional security and identified emerging health security threats such as the possibility of bio-weaponization of infectious diseases, transnational threat from infectious diseases, and lack of treatment capacity in the event of mass cases.
Although the military is well prepared for traditional security threats, it needs to be prepared in the event of unexpected national disasters such as new infectious diseases. In this study, we suggest how to develop a response concept to biological warfare, strengthening infectious diseases precision analysis capabilities, establishing a technical information support system for infectious diseases, strengthening medical treatment capabilities for mass infectious diseases.
