I'm a physicist and I've got friends in biomedicine/medical sciences. Some of them are involved in bleeding edge research for new anti-pathogen measures. I've had many a discussion with them about infectious diseases, outbreaks and antibiotics.

They have know for a long time that antibiotics are a dead end. Antibiotics only postpone the inevitable and they will be used as long as they work. There's no point in developing new antibiotics, because they're difficult to tailor for specific diseases and in the long run they make us even more vulnerable to infectious diseases.

The solution is to find a balance between us and the germs. Our environment and us are already full of bacteria. Some of that flora is actually benficial to us. If we didn't have a specific set of germs on our skin, we'd be overrun by fungal skin infections and we wouldn't be able to digest our food properly. We're living in symbiosis with these micro-organisms.

The future state-of-the-art methods for fighting harmful bacteria will be based on genetically engineered bacteria and viruses.

You get an infection, a sample is taken and the genes and structure are analysed. The harmful pathogen is then genetically engineered into a custom-made new version. The damage the harmful pathogens do is due to the chemical substances (biotoxins) they emit as a result of their natural metabolism. In the future, their metabolism is modified via genetic engineering so that they survive in the human body even better than the original version, but now they don't emit those harmful metabolic by-products anymore.

Since the new pathogen now survives in the human body and is actually better than the original harmful pathogen, there's no need for it to evolve further (which is why the bacteria become resistent to antibiotics). It will compete with and eventually overrun the harmful pathogen. It doesn't cause harm to a human anymore, because the metabolism has been changed. A peaceful co-existence follows.

So, instead of destroying bacteria, we need to find ways to live with them. That's the only way we can win.
