On-Service ID Link-o-Rama — Osmosis Edition

First-year ID fellows this time of year bring a lot to inpatient consult rotations. Years of high-volume inpatient care have sharpened their clinical instincts, and at this point they have an impressive fund of ID knowledge. Plus, the fellow on our current rotation gets along great with everyone — patients and consulting clinicians alike — […]

SNAP Trial Helps Resolve Long-Running Controversies Over Management of Staph Bacteremia

For those who do hospital-based patient care, the significance of Staphylococcus aureus bacteremia (SAB) cannot be overstated. It’s one of the most frequent reasons for infectious disease consultations — and for good reason: when mismanaged or complicated, it can lead to high morbidity, a myriad of complications, and a disturbingly high mortality rate. Despite its clinical […]

Looking Back at a Defunct ID Meeting — and Ahead to a Thriving One

Back in prehistoric times, many ID doctors and microbiologists would gather each fall at a meeting to review the latest antimicrobial clinical trials and promising “bug-drug” studies of novel compounds in development. The meeting was called the Interscience Conference on Antimicrobial Agents and Chemotherapy, abbreviated ICAAC. There were a bunch of problems with ICAAC. First, […]

Gepotidacin — New Antibiotic or Rare Tropical Bird?

Imagine you’re birdwatching in the Costa Rican rainforest, Merlin app in hand. A flash of iridescent blue catches your eye. You scan the canopy and whisper excitedly: Look, it’s the elusive Blujepa! A rare sighting! No, not a real bird, but the brand name of gepotidacin, something rarer — and arguably more exciting — than […]

Really Rapid Review: CROI 2025 San Francisco

Wow, that was an interesting conference — in ways both good and bad. The good part was the content, as the Conference on Retroviruses and Opportunistic Infections (CROI) is our leading HIV research conference. There was plenty of interesting stuff. The not-so-good part was the stunned state of many HIV clinicians and researchers. So much of […]

What Is the Future of Treatments for COVID-19?

In this raging flu season, where people with influenza-related illness outnumber those with COVID-19 for the first time since the pandemic hit in 2020, we might be fooled into thinking that we no longer need better treatments for COVID-19. This would be a mistake — this virus still causes much misery, peaking each winter but […]

Tragic Childhood Death from Measles Reminds Us That Some Don’t Understand Either the Medical Significance or the Human Heart

My ID colleague Dr. Adam Ratner, Chief of Pediatric ID at NYU Medical Center, just published an insightful and remarkably timely book called Booster Shots:  The Urgent Lessons of Measles and the Uncertain Future of Children’s Health. Chapter Six is entitled “Making Nothing Happen,” and it starts off with this especially profound paragraph: Prevention can be a […]

The Language Grouch Returns

If you’re an ID doctor, there’s a lot to be grouchy about these days. This. This. THIS! The list is long — and growing. Longtime readers with an interest in ID: I ask that you please contact your members of Congress to convey the harmful impacts of the workforce cuts at the CDC, NIH, VA, […]

This Year Influenza Came Back to Remind Us It’s Not Messing Around

If it seems like pretty much everyone you know either has the flu or is recovering from it, it’s because we’re in the middle of the worst flu season in over a decade. Take a look at this figure, from our state’s surveillance data, updated yesterday: The result of all this “influenza-like illness”? Patients are deluging outpatient […]

Could This Be the End of PEPFAR?

Short email from a longtime colleague, working in Africa at a PEPFAR site: Without USAID, PEPFAR is essentially dead. I got chills reading this. PEPFAR, the abbreviation for the President’s Emergency Plan for AIDS Relief, started in 2003 under the direction of President George W. Bush. To say it’s been a resounding success undersells the impact of the […]
