Tivi-que? Why Dolutegravir is the GOAT(Thus Far)

Stop me if I have mentioned this before, but HIV therapy is actually quite simple these days. No longer do patients have to take a “cocktail” of medications (whatever that means, I typically think of the alcoholic cocktail) with regimens being streamlined into one simple pill: Atripla, Odefsy, Genvoya/Stribild, Triumeq, and the (relatively) new kid

Vibrio Vulnificus is one of those board questions that pops up occasionally.
