The world is witnessing COVID-19 pandemic. The current crisis has several repercussions, across society. There have been strong restrictions imposed by various countries: from general health advisories to quarantines and isolations, to curbing the trans-border movement of people.

Under such circumstances, it is pertinent to look into the issues like obligations, authority, and procedures for dealing with such situations under International Law. Have the current governments in all countries complied with it? What role has International Law played through its institutions especially the role of the World Health Organization (WHO).

The paper concludes by answering these queries based on current empirical data and descriptive research analysis
