Julian Osei spends his week deciding which infections actually need a drug and which need time, and he brings that same triage to the forum. He trained in internal medicine, then infectious disease, and he now leads the stewardship programme that governs how antibiotics get used in his hospital, so he has watched both the good a prescription can do and the harm it can cause.
On the threads his instinct is to slow people down. He explains why an antibiotic does nothing for a virus, why a fluoroquinolone is a heavier tool than a simple penicillin, and why a parasite has to be named before it is treated. He is patient with questions shaped by something a reader saw online, because he would rather explain than scold.
He covers the anti-infective corner of the site: one antiparasitic and one broad-spectrum antibiotic that deserves a real flag. Nothing he writes here is a prescription. It is the unhurried version of the conversation he has in clinic every day.
