Here's an article in Australian Fairfax Media: "Fears new wonder drug could lead to STI epidemic"
It refers to this article in The Lancet: "Community-level changes in condom use and uptake of HIV pre-exposure prophylaxis by gay and bisexual men in Melbourne and Sydney, Australia: results of repeated behavioural surveillance in 2013–17"
Here's the key take-away from the Fairfax article:
An international 2016 study of men who have sex with men found the chances of contracting chlamydia, gonorrhoea and syphilis were increased 11, 24, and 44-fold respectively in PrEP users. Fears have now been raised that these staggering numbers might be replicated in Australia.
