The World Health Organization (WHO) doesn't publish a ranked list of the top 100 or any number of medical schools globally. WHO's role is primarily focused on global health issues and setting standards, not ranking educational institutions. Rankings of medical schools are typically produced by independent organizations like QS, Times Higher Education, or US News & World Report, and their methodologies differ. These rankings often focus on research output, faculty reputation, and other factors, which may not align with all aspects of quality medical education.
Therefore, I cannot provide you with a WHO-recognized top 100 list because such a list doesn't exist. To find rankings, you would need to consult the aforementioned ranking organizations and understand that these are just one perspective on quality. The "best" medical school for an individual depends heavily on their specific goals and preferences.
