We have one at UW. It is not a fellowship by a Residency learning pathway that leads to an American Academy of HIV Medicine certification (i.e. HIV primary care). See the link below, it is a tiny.cc link to our HIV pathway summary. The track at UW is competitive and you need to have a track record of interest in HIV medicine and plans to pursue a career in HIV care.
