Loads of people in the world don't get access to proper medical care when they need it - when they're affected by disaster, conflict, epidemics or just no access.
The good thing about MSF is that they treat ANYONE who needs it regardless of things like religion/political affiliation/gender/race and all those dividing lines that people seem to create wars about.
Dig deep so FoTW can get doctors to places that wouldn't otherwise be reached.
