There is no time more opportune to review the workings of the International Health Regulations (IHR) than the present COVID-19 crisis. This article analyses the theoretical and practical aspects of international public health law (IPHL), particularly the IHR, to argue that it is woefully unprepared to protect human rights in times of a global public health crisis. To rectify this, the article argues that the IHR should design effective risk reduction and response strategies by incorporating concepts from international disaster law (IDL). Along similar lines, this article suggests that IDL also has a lot to learn from IPHL in terms of greater internationalisation and institutionalisation. Institutionalisation of IDL on par with IPHL will provide it with greater legitimacy, transparency and accountability. This article argues that greater cross-pollination of ideas between IDL and IPHL is necessary in order to make these disciplines more relevant for the future.
