Let's keep the rant train going.
@MedicalDoctorV is so spot on. If you want to do field work, fine, more power to you, but focus on
sustainability over anything else. Too often field work is just a kind voluntourism that exploits the poor for the warm and fuzzy feelings of the rich. It's also increasingly being used as a marketing tool for medical schools and residencies, with questionable benefit (or even harm) for host nations. If you really want to do good, either work on
structural issues (which takes time and committed effort) or earn as much money as you can as an attending and give that money to people who know what they're doing. Generally speaking, so many more lives would be saved with 1 week of attending
salary than with 1 week of attending
time.
But you asked about policy. I've done policy work at WHO. It's not as exciting as some may think. 9-5, European hours, bureaucracy like you would not believe, resource and morale depleted. The stories I could tell: one nation point-blank refused to wire transfer their funding obligation for the quarter, the Director-General then cried during a sub-committee meeting of the World Health Assembly, and the delegate from Argentina half-teasingly started singing "Don't Cry For Me Argentina"--yes, this actually happened. Donor-dependency, bitter tears, and cynicism. Welcome to global health policy.
Mostly it's an administrative and quasi-regulatory organisation that provides technical expertise when asked. That means the work is generally quite boring. Lots of writing, lots of coordinating, lots of research, lots of meetings, lots of memos, lots of talk--not much "action" (which is fair, because this kind of work is really damn hard with many moving parts.). Like a corporate job really. I know I'm coming across as jaded, and I am. (Again, the stories I could tell.) But I've developed a
huge amount of respect for the true-believers. Plus Geneve is a great city (though it's much cheaper and nicer to live across the border in Ferney-Voltaire). They take interns, but you'll need to secure your own funding.
This is just one tiny sliver of global health. (And I never worked on the crisis/resource coordination side of things at WHO, which is very different.) Global health also includes NGOs like MSF, Gates Foundation, ICRC (each with their own agendas that may or may not comport with reality), GOs like USAID or UNAID/PEPFAR, and a million other things. All very, very, very different.
But here's the thing:
you are valuable. A MD gets you very far and opens lots of doors, mostly because there's little compensation and not many are interested in committing for the long haul.
@MedicalDoctorV's advice is perfect:
you gotta be picky, with your time, with your mentors, and with your commitments. Doing so will set you on the right path.
