"Refuses to seek treatment" is not necessarily a fair description of these people's actions. They can get HIV at birth through their mother without engaging in any "at risk" behavior. They can have it and not know it. They can lack education. They can lack resources. They can have received misinformation.

There are places where the official government-endorsed treatment for HIV was sex with a virgin. There are religious notions that declare use of birth control sinful. There are moral police that call education about safe sex (instead of abstinence) wrong, despite its proven efficacy.
