Even if You Think “The Pandemic Is Over” — Let’s Make In-Person Meetings Safer

“The pandemic is over.” Someone very famous used these words recently, triggering all kinds of controversy. While most ID clinicians groaned at the comment, knowing that it would be taken out of context, repeated in headlines without any of the President’s cautionary statements, and fuel Covid denialists, it’s also worth acknowledging that most of the country really […]

Mayo Clinic Study on Paxlovid Outcomes is Reassuring — but Likely Underestimates Rebound Rate

Over at Clinical Infectious Diseases, researchers from the Mayo Clinic published a retrospective analysis of nirmatrelvir/r (Paxlovid) treatment, with a careful review of each patient’s chart. The goal was to determine the clinical outcomes after the 5-day treatment course, with a focus on the frequency of rebounds — a topic of great clinical interest but with little […]

More on Relapses after Paxlovid Treatment for COVID-19

Unless you’ve been hiding under a rock, you’ve heard that some people treated for COVID-19 with nirmatrelvir/ritonavir (Paxlovid) experience a relapse in illness shortly after stopping treatment. It’s both a recurrence of symptoms and a positive antigen test — sometimes after the test became negative. One case report published as a pre-print shows that a relapse can have […]

Yes, Relapses After Paxlovid Happen — Now What?

Around two weeks ago, one of my long-term, very stable patients with HIV called me saying she’d just been diagnosed with COVID-19. Over 60 with hypertension, and overweight, she qualified for nirmatrelvir/r (Paxlovid) under the Emergency Use Authorization (EUA), and took it without problem. (Certain details changed for confidentiality.) In fact, she started to improve within 24 […]

Should We Prescribe Nirmatrelvir/r (Paxlovid) to Low-Risk COVID-19 Patients?

The top recommended treatment for high-risk outpatients with COVID-19 in the NIH Guidelines is nirmatrelvir/r (Paxlovid). It’s quite clear why. In the EPIC-HR study, unvaccinated people at high risk for severe outcomes had an 89% reduction in the risk for hospitalization or death compared to placebo. If we just look at mortality — another important endpoint, […]

What Have We Learned from the Pandemic So Far?

Dear Readers, I need your help. Recently one of my colleagues reached out and asked if I could give a talk to his research group. “Just give one of your canned Covid talks,” he said. Ha. Needless to say — but I will say it anyway — he’s not an ID doctor. Otherwise he’d know that, as I’ve said […]

The Rise and Fall of Ivermectin — 1 Year Later

Here’s a confession few board-certified ID doctors will make — there was a brief period when I thought ivermectin could very well be an effective treatment for COVID-19. It wasn’t when the in vitro data first came out. Therapeutic concentrations were not achievable in humans. Nor when the anecdotal reports started pouring in, and sometimes making news. […]

Prior COVID-19 Is No Guarantee of Immunity

I’m no immunologist — a fact made vividly obvious to me several years ago when asked to teach a weekly medical student section that included cases and problem sets. The challenge was that the course combined immunology and microbiology. I was on much firmer ground with the microbiology than the immunology, the latter often a wonderfully […]

Novak Djokovic Thinks He Can Play by His Own Rules — Australia Says Think Again

There was a truly talented kid on my ninth grade basketball team — let’s call him Robbie G. He was a terrific player, fast and confident on the court, always eager to play, and just brimming with enthusiasm for the game. Every time he scored, the team and crowd (small as it was) buzzed with excitement […]

The Pandemic Life of an ID Doctor — in Graphic Form

Three works of art sit on my father’s desk in his office, gifts from his children from when we were in grade school. From my brother Ben, there’s a little bear, or perhaps it’s some other burly quadruped — easily a B+ in his art class from the 1960s, likely an A- now with grade inflation. A […]
