Marcus Bellinger spends his working week deciding which infections need a drug and which need patience, and he brings that same triage to the forum. He trained in internal medicine, then in infectious disease, and he sits on the hospital committee that decides how antibiotics get used, so he has watched both the good and the harm that a prescription pad can do.
On the threads his instinct is to slow people down. He will explain why an antibiotic does nothing for a virus, why finishing the course is not always the rule it once was, and why a parasite has to be named before it is treated. He is patient with the 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 workhorse antibiotic. Nothing he writes here is a prescription. It is the unhurried version of the conversation he has in clinic every day.
