As a doctor who has worked in hospitals across multiple continents, I'm witnessing the antibiotic resistance crisis firsthand, and it's more alarming than most people realize. We're heading toward a postantibiotic era where common infections could become deadly again.

The antibiotic resistance crisis is driven by overuse and misuse of antibiotics in human medicine, rampant use in agriculture (about 70% of antibiotics globally are used in livestock), and poor infection control in healthcare settings. I've seen patients with infections resistant to every available antibiotic.

What makes the antibiotic resistance crisis particularly concerning is that drug development has slowed dramatically. Pharmaceutical companies aren't investing in new antibiotics because they're not as profitable as drugs for chronic conditions. We're losing our arsenal faster than we're replenishing it.

I've worked in countries where antibiotics are available over the counter without prescription, leading to inappropriate use. But even in countries with stricter regulations, resistance spreads through global travel and trade.

Is there any realistic path to addressing the antibiotic resistance crisis? Or are we destined to return to a world where a simple cut or childbirth could be fatal due to infection?

The antibiotic resistance crisis requires a One Health approach that recognizes the connections between human health, animal health, and environmental health. Overuse of antibiotics in agriculture is a major driver of resistance, and resistant bacteria can spread through food, water, and direct contact.

I've worked on programs that promote responsible antibiotic use in both human and animal health. This includes training for healthcare providers on appropriate prescribing, regulations on antibiotic use in agriculture, and public education about not demanding antibiotics for viral infections.

But these measures need to be implemented globally. Resistance doesn't respect borders, so efforts in one country can be undermined by practices in another. We need international cooperation and standards to address the antibiotic resistance crisis effectively.

The economic incentives driving the antibiotic resistance crisis are perverse. Pharmaceutical companies have little incentive to develop new antibiotics because they're used sparingly (to preserve effectiveness) and for short courses. Meanwhile, companies profit from selling antibiotics for growth promotion in animals.

I've analyzed proposals for new economic models to address the antibiotic resistance crisis: push funding (grants for research), pull funding (prizes for successful development), and subscription models where governments pay for access to antibiotics rather than peruse.

But changing these economic incentives requires political will and international coordination. Individual countries acting alone can't solve the antibiotic resistance crisis, but getting global agreement on new economic models for antibiotic development is challenging.

Climate change may be exacerbating the antibiotic resistance crisis in ways we're only beginning to understand. Warmer temperatures can increase bacterial growth rates and potentially spread of resistance genes. Extreme weather events can damage healthcare infrastructure and disrupt antibiotic supply chains.

I've worked in regions hit by climate disasters where damaged hospitals struggled with infection control, potentially contributing to the spread of resistant bacteria. And changing disease patterns due to climate change may lead to increased antibiotic use for new or expanding infectious diseases.

Addressing the antibiotic resistance crisis therefore needs to consider climate resilience. Healthcare systems need to be prepared to maintain infection control and appropriate antibiotic use even during climate related disruptions.
