The most likely reason for lower condom use, is the change of how HIV is perceived. In the 80s it was considered a death sentence, now it is a chronic condition. Not to mention the very low chance of infection (in all but anal sex).
I think you’re being alarmist with the whole bacterial resistance thing. It is happening very slowly (not just with stds), but it is not like you are likely to actually contract one of these forms. I admit I’m not sure about the US, but here in the Netherlands the authorities very clearly state that the clap is “easily treatable”, while mentioning that there are some instances of resistent bacteria abroad… but nothing in the Netherlands yet.
Just to point out: for many people the reality/view of stds is exactly the one you had in the 70s. You get a single shot or a single pill and a week later the std is history.
I admit I didn’t read the link really carefully, but as far as I could tell, that would include people in sexually monogamous relationships. So for instance a big part of the reason that fewer men age 25 to 34 use a condom may be that more of them are married (and many of those are trying to have kids).
Who would pay money for a wildly inaccurate test that tells you something you already know? If you’ve been having sex then there’s always some chance you might have a testable STD (and almost certain to have some strain of HPV). Paying money for a kit that tells you ‘well, possibly you have this, but maybe not, we can’t tell you in a sure enough fashion that you either need to worry or not so no matter what this test says go to a doctor before relying on the information’ doesn’t make a lot of sense; people who actually care about their sexual health get STD tests at some regular interval, people who don’t care aren’t going to spend money on a test that doesn’t work reliably.
Research has actually created some STDs. Herpes wasn’t considered an STD for a long time, it was treated as an annoyance like cold sores and didn’t even come up in medical literature as a condition to worry about. When drug companies developed antiviral drugs that could treat it in the mid-70s, they created a market for the drug by running advertising campaigns stigmatizing it, and that’s why herpes is considered a Big Deal today.
If I had a dog, and was single, I’d train it to sniff out STDs. No idea where I’d get samples, though; pretty sure the local CVS doesn’t have that stuff, even behind the counter. Not in a bottle, at least.
The “killer clap” BS has been around at least since the war in Vietnam. In fact, the gonococcus is a frail bug that can be wiped out in hours by a single dose of any of a wide variety of antimicrobials. The problem is that it is good at becoming less susceptible over time to specific antimicrobials. I am unaware of any reports of gonorrhea being resistant to all antimicrobials. It is just that antimicrobial susceptibility testing might be required to find out what will work in each case. (Antimicrobial susceptibility testing is routine for many infections caused by other bacterial but it has never been routine for gonorrhea.)
In practice, to control gonorrhea, you want an antimicrobial regimen that is safe, cheap, well tolerated and will cure every infection 100% of the time so that you can be confident that your patient is non-infectious within hours after leaving the clinic. In the 1990s, there were quite a few single-dose regimens to choose from. Now, the choice is down to pretty much just one drug.
What this means is not that gonorrhea is becoming untreatable, what it means is that efficient treatment of gonorrhea will require antimicrobial susceptibility testing or the initial use of more than one drug, or both. Nevertheless, I advise condom use in relationships that might not be monogamous.
