I will start since I just went through the match cycle. I did my thesis through the institute on dengue seroprevalence in a rural province in the DR. It was a real field study, not just a lit review, and I ended up with a co authored publication in a public health journal before I applied. I matched into internal medicine at a community program in the midwest and I can tell you that at three of my seven interviews the program director or a faculty member specifically brought up the tropical medicine research. One of them had a global health track and basically said it was a differentiating factor for them. I genuinely think it helped.
