Declaring a public health emergency of international concern would enable an equitable response rooted in the principles and ethics of public health: care and support for those most affected; large-scale prevention; and surveillance of impacts. It would enable international collaboration, catalyze finance and ensure central coordination and support from the WHO.

Yep, and that's precisely why it'll never happen. Equity, ethics, public health, care, support, collaboration? What are we, communists?
