Question
Is HIV reinfection a myth?
26 September 2018. Related: All topics, HIV reinfection (superinfection).
Hi, I was wondering why does your site mention reinfection/superinfection?
I can’t see how it is possible to be infected with the same virus, more than once. Your book and site is generally very useful, but if this is just a myth it just adds to the taboo surrounding HIV.
Answer
Hi
Thanks for your feedback which is always appreciated.
Unfortunately though, reinfection is not a myth. It is easily possible because HIV isn’t a single fixed virus. Even though infection is often with a single virus, this develops and changes within everyone until we all have a soup of slightly different types of HIV.
There are already about 30 major HIV sub-types (called clades) that have significant differences, These could only have occurred by reinfection. Sub-types A, B, C and D etc have structural differences that sometimes affects how quickly HIV progresses or how drug resistance develops.
However, the clinical implications are only if there is drug resistance. These cases are much more rare, but they are important enough to have been published many times.
The good news is that having an undetectable viral load with stop reinfection just as well as it stops infection ie reducing the risk to zero.
Hi Tshidi.
Weight loss can be due to lot of reasons. However you having unprotected sex with your partner won’t be one of them.
Me and my partner are both possitive with undetectable viral load we have been having unprotected sex because we trying for a baby it’s been 6months now,I went to the clinic yesterday and realized that my weight has gone down by 5kg could it be because of unprotected sex,the nurses said they need to monitor my weight I’m starting to be scared could it mean something alarming
