Here's some genuinely good public health news for a change: sexually transmitted disease cases in San Francisco dropped significantly in 2025, with syphilis cases falling 24%, chlamydia down 18%, and gonorrhea declining 5% compared to the prior year.

So what's behind the improvement? Not a sudden citywide vow of celibacy. Public health officials are pointing to the increased use of doxycycline, an antibiotic taken as a preventive measure against STD infection — essentially a prophylactic approach that's been gaining traction in recent years.

This is worth celebrating, and it's also worth noting why it's worth celebrating. This is a case where a practical, individual-level medical intervention — not a massive new government program, not a sprawling awareness campaign with a seven-figure budget — appears to be driving real results. People making informed choices about their own health, armed with better tools, and the numbers move in the right direction. Imagine that.

San Francisco has long been a city with elevated STD rates, partly as a function of being a major urban center and partly due to demographics and social factors unique to the city. For years, the response from City Hall has leaned heavily on public health bureaucracy — more outreach coordinators, more campaigns, more funding requests. And yet the numbers stubbornly refused to cooperate.

Now a straightforward pharmaceutical option is doing what layers of institutional effort struggled to accomplish. There's a lesson in there for policymakers, if they're willing to hear it: sometimes the best public health strategy is giving individuals access to effective tools and getting out of the way.

Of course, antibiotics aren't a silver bullet. Overuse raises legitimate concerns about resistance, and a 5% drop in gonorrhea is modest compared to the syphilis numbers. But the trendline is encouraging. Let's hope the city takes the right lesson from this — empower individuals, trust the science, and resist the urge to claim credit with another expensive program.
