Global health is ... c/o King & Koski (2020)

Use of the word 'global' in health care is common: from global assessment; global as in a pandemic, as per Covid which for a time closed down most human activity across the world; the global health workforce; and global health crises, that must include the climate crisis and pollution. Universal health coverage, allied with universal healthcare access, refers to (national and aspirational ...) global access to quality health services. 

Above, 'global health' has itself already occurred several times. I've posted about global health on a great many occasions on behalf of other parties.

Defining global health in the context of public health, King and Koski (2020) write:

'We propose the following definition:
global health is public health somewhere else.'

More specifically, they add: 

'Global health as a field is not distinguished by its aspirations, methods of research and practice, intervention strategies or even geographical area per se, but rather by a particular relationship between its practitioners and its recipients: a person engages in global health when they practise public health somewhere—a community, a political entity, a geographical space—that they do not call home.'

To apply Hodges' model to global health, there must be another definition.
