There are two types of HIV, there is what is called hiv-1 and another one called hiv-2. Hiv-1 is more prevalent in North Americans and Europeans hiv-2 is more prevalent in African-Americans or people living in Africa. of those two strains those streets can be broken down into even more strains.

No, it's just like a generic brand of aspirin versus Bayer.... Different pharmaceutical companies have launched their antivirals. Along with the fact that different people respond to ARTs in a different way... what works for you may not necessarily work for your husband ,...depending on the strain and his DNA.. I've attached the drug chart for you. Thanks for the question.🤗🤗🤗. https://www.poz.com/article/2019-hiv-drug-chart

no. 199 and less is concidered AIDS. 200 is the lowest of low for HIV.

I'd like to add, your spouse may have a different strain. Then when it entered your body it changed. That is why they keep finding new medications, because HIV mutates. It could also depend on your blood types if they are different. It could also be genetics. Maybe one of you your body can fight it better than the other, so one will need a stronger prescription.

not what i meant, but thanks... the reason I ask, since I was infected by spouse why aren't we both on the same exact meds? just wanted to know if there was some other hidden factor that I'm not seeing.
