They hear it through memory. “Airborne” is no longer just a techn

A science-based breakdown of the hantavirus cruise outbreak, including airborne transmission, Andes virus, person-to-person spread, and how to communicate honestly during evolving outbreaks.

Issue #3 It Passes Between Us On transmission, transformation, and the language before pathogens Welcome to Field Notes. Each week, I take one idea from the episode and follow it where it leads. For Outbreak After Dark, that idea isn’t just biological—it’s how we make sense of what we don’t fully understand. If you want the full story, you can read or listen to the episode here.

Summary Epstein–Barr virus is one of the most common infections in the world—by adulthood, nearly 95% of people carry it. Most remember it, if at all, as “just mono.” A brief illness. A recovery. The end of the story. Except it isn’t. EBV doesn’t leave. It stays—inside the very immune cells responsible for remembering infection. For most people, it exists quietly, held in check by the immune system. But under certain conditions, that balance can shift, linking this common vir

Murine typhus is a flea-borne infection often missed due to nonspecific symptoms and subtle presentation. This episode explores its transmission, urban ecology, and why infections that don’t fit expectations are frequently overlooked.

Issue #1 When Systems Adapt On flexibility, vectors, and persistence Welcome to the first issue of Field Notes.

In the Margins What makes murine typhus unusual isn’t the pathogen—it’s the flexibility of the system. The transmission cycle used to be a closed loop of rats, fleas, and humans. Now the system inclu

A one-year anniversary episode of Infectious Dose exploring how science communication, misinformation, trust, and storytelling shape how we understand infectious disease.
