Global health

The Disease burden is not equally spread across countries.

Burden, needs, investment, and research

Disease classification

One challenge to study global health needs/burden is mapping difference Disease classification systems such as ICD, MeSH, Global Burden of Disease, Disease Ontology etc. Unified Medical Language System exists, but is incomplete. Studies such as Yegros-Yegros2020exploring and Evans2014attention developed their own mappings across classification systems.
