Minorities have a higher rate of HIV than whites. This is true in the south, probably the southwest also.
Here is a quote from Lloyds article"
"In 2018, 37,832 people received an HIV diagnosis, according to the CDC. Among those, 42% were black or African American, 27% were Hispanic or Latino, and 25% were white. Also among the new diagnoses, 69% were among gay, bisexual, and other men who have sex with men (sometimes referred to as MSM); 24% were among heterosexuals, and 7% were among people who inject drugs."
The heterosexuals were probably men who visit prostitutes or prostitutes, or had relations with a drug user who got it by injections.
I don't think anyone here will have a problem with HIV. Stay out of them places.
