End-of-Summer Musings — Hepatitis B, Dalbavancin, Alpha-Gal, and More

The last time I did one of these quick “musings” posts, I listed 21, and someone asked me, “Why 21?” The answer — obviously — is that I originally planned on writing 20, but then had to add a 21st, just because that’s exactly how many points you need to win a ping pong game. […]

Does the Fact That AI Is Brilliant at Writing “Learning Objectives” Prove They’re Not Really Needed?

Recently, I was invited to speak at a primary care conference on a terrific topic: “Can’t Miss Diagnoses in ID for the PCP.” Love it. So many great examples come to mind — endocarditis, Lemierre syndrome, vertebral osteomyelitis, acute HIV. A wonderful opportunity to teach about the “rare but there” diagnoses hidden among everyday outpatient […]

Who Gets Sent to ID Clinic? A Field Guide to Outpatient Referrals

Sometimes people ask me what kind of cases get referred to ID doctors in the outpatient setting. Despite what the latest television series might suggest, it’s rarely suspected Ebola (fortunately) or Tsutsugamushi fever — a disease that is much more fun to say by its Japanese name than its common one, scrub typhus. (In Japanese, “tsutsuga” […]

Ceftriaxone Is a Narrow Antibiotic Now — and Other Musings

In no particular order, 20 things I’ve found interesting lately — a mix of ID (mostly), language quirks, clinical stuff, even tennis, and an apology (#21) at the very end. Bonus videos embedded because we all need a break. 1. Isn’t it amazing how, over time, an antibiotic once considered “broad spectrum” later becomes the […]

Two Pandemics, Compared: Reflections on HIV and COVID-19

“Dr. Sax, what’s it like to have lived through two pandemics as an ID doctor?” The question came from a brand-new intern during afternoon sign-out. I took a breath — because wow, were they different. HIV: It Felt Like A Calling, One Miraculously Rewarded I started my internship in 1987, six years after the first […]

Federal HIV Guidelines Face a Shutdown — A Critical Loss for Clinicians and Patients

Each week, our HIV clinical group gathers to review active patients, share updates, and celebrate good news. On our whiteboard, we list four columns: Inpatients, Outpatients, Issues, and Celebrations. This week, under “Issues,” one of my colleagues wrote: HIV Guidelines:  ☹️ Yes, you read that right. This week, we learned that the federal HIV guidelines […]

Why the Sudden Firing of ACIP Members Should Put Every Clinician on High Alert

There are certain irrefutable verities when, like me, you’re an infectious diseases specialist married to a pediatrician. Here are our top two, which are deeply interrelated: Infectious deaths in children, or severe illnesses that lead to lifelong disability, are more devastating than similar events in adults. Each such case in a baby or child is […]

How ID Doctors Get Paid, Part 2: Infection Control and Other Invaluable (but Often Invisible) Work

Before getting to today’s main topic, allow me a brief protest — three recent vaccine-related actions that reek of profound (and misguided) vaccine distrust from HHS leadership. They are: Cancellation of a grant to develop an H5N1 vaccine. Preparation for this looming pandemic threat is critical, and there’s arguably no better way than having a […]

How ID Doctors Get Paid — The Bread, Butter, and Budget Deficits of Infectious Diseases

Two decades ago, Dr. Atul Gawande wrote a memorable piece for The New Yorker about how doctors in the United States get paid. Providing a nice mix of self-reflection about his own experience and some skillful reporting, he described the challenging process of figuring out what he, a newly hired surgeon, should earn for a […]
