>"If one man is taking PrEP and the other one is virally suppressed, there's no HIV risk at all," she says. "So why use condoms if you don't mind having a touch of syphilis?"
Humans really do take for granted the efficacy of antibacterials and antibiotics across the board.
These sort of harmful bacteria are completely and safely treatable now in most people, but the real potential threat is breeding drug resistant strains of bacteria, microorganisms and viruses. We shouldn't treat these fantastic tools like a pass to do whatever, we should instead use them sparingly and curb behavior. There are plenty of simple preventative practices than can reduce ever needing such treatments while mostly being able to continue doing what you'd like. A huge amount of these infections could be reduced drastically just by using a condom.
Rely on those prevention approaches first and drugs/treatment second to reduce the risk of creating situations where treatments don't exist. This can be said about a huge swath of preventable disease in the US. A bit of diet, exercise, and an once of prevention is worth its weight in gold.
