One of the things I like about STI is that you can read the thing without paying and, yes, I've seen this article (and its twin on non-virals).
Those two are case reports, not studies, and the rest of the section shows the problems on relying on them: people under-report high risk behaviour. It's far more acceptable to say you caught HIV via sucking someone than to talk about your barebacking or IV drug use.
Apologies - I tend to use the word studies colloquially to refer to all sources. To be fair that is a very good point, but it doesn't
rule out the possibility that transmission has indeed occurred in these instances, just the validity of the sources themselves. It would be equally possible to apply this logic to CIM sources, although perhaps to a lesser degree.
Taking a slightly different tack, there seem to be sources that show (
link &
link - unfortunately I have only been able to read the abstracts because my university is not a subcriber to these journals, so if there is any ... y'know ... massive methodological flaws that I don't know about, then do tell me) that HIV has been found in pre-ejaculate, and it therefore seems reasonable to intuit that there is a risk along the same vein as CIM.
It should be noted however that I am a humanaties student, and so am not familiar at all with journals in this area, so apologies if I seem uninformed. I am by no means trying to appear like I am expert in the area - I am not by a long way - I am just trying to iron out my own intuitions with the accepted knowledge.
