typed we re now seeing up to five percent of this strain slowly getting into the into the hiv population so what in your opinion needs to be done to limit the spread of this non b. type of hiv virus. well i think we need to look at viruses better because even though subtype b. which is the western subtype only accounts for twelve percent of the total number of hiv in the world most of the research on treatment ninety percent of the research on treatment is for a subtype b. but the genetic difference between some be and the other subtypes can be as much as twenty five to thirty five percent of its whole genetic material so that s that s you know that s really far that s like the difference between a coral end and maybe a dog so it s a very big genetic distance and so it s it i think it s dangerous to assume
