Good morning, I asked my doctor this question before and she said that "if a person has strand A and another person has strand B. If they are not taking their meds and not protecting themselves they can create a strand C. Which means they would have to find a new meds that would replace your other meds; because they would no longer work. She said A strand woul be considered sensitive ( means your acceptable to all meds); and Strand B would be considered resistance ( meaning you couldn't take any kind of meds, they would have to find some thing that works." Another thing is Truvada it contains HIV so that it no longer spreads, and the other med is to contain the Virus so that its' so small that it's undetectable. The virus is still in your blood both meds work together to keep you undetectable. Your CD4 count ( your T4 cells) show your level of your immune system. I hope this helps.

Truvada used for the already positive should only be used in conjunction with at least 2 other kinds of antiretrovirals. Part of the CDC recommendations for successfully prescribing Truvada is frequent testing, especially when the risk factors are greater, like with sex workers, or frequent and different partners in any scenario. If the person with HIV is undetectable, there can be no Truvada resistant strain because in order for the virus to adapt, there needs to be a substantial viral load. I’m not even sure that answers your question, but I hope it gives some insight. If you’re positive, stay treated and undetectable, and if you’re not, do your best to know your sexual partners.

Not necessarily. Remember that when you’re on a cocktail there is more than one medication involved. Truvada is doing great in its capacity to keep negative people from becoming positive; however there are other people that use it as a reason to continue to bareback; not with standing that there are other STD’s that they can get aside from HIV. Now if you’re already positive Truvada is a crucial part of a cocktail that you would be possibly taking but, it is only a part not the whole thing. As far as Truvada stopping a new strain from developing, that has yet to be tested; yet alone proven. It may also be a question that should be answered potentially from a researcher since they would probably be more knowledgeable than your doctor who is treating you. Your question is insightful, and ultimately may not be able to be answered just yet. @A myHIVteam Member

I've been around a long time with this. There's some things to consider. Truvada just like any other can and will eventually lose its benifits. The virus can and will transform itself around the drug and become non effective. All your thoughts are right but only to an extent. I'm not your doc and I've not seen your history, labs... while it's great to ask us, you need to ask these questions to your doctor.

I took @Truvada for years and can't honestly answer that question. I can only say that in order to prevent from catching a new strand you should protect yourself by wrapping up.
