Hm. That's not very biopsychosocial. Plus, infections are good for us now, apparently. They top up our immune muscles, or whatever. Can't go around scaring people about viruses and bacteria, they're so common, they're everywhere, that would make people nervous wrecks, and so on. People just have to learn to live with them. It's either that or crippling anxiety, apparently.
At some point medicine is going to have to decide whether to continue with the biopsychosocial crap, or accept the full implications of the germ theory of disease. Most likely it will be one, and then, after disastrous regression, the other. There's only one order this can take, and it's the most likely one. After all, can't have cheap apps do the one that works. And it's not about whether something actually works, but about how it feels.
