Infectious Dose

Just a Little Wider | Month of the Macabre He's already been waiting more than an hour. He's sick, exhausted, and ready to leave. But the dentist can see him now. Surely it won't take long. Then the dentist finds something unusual. As the exam continues, the patient grows increasingly ill. The dentist's behavior becomes more disturbing. Familiar sounds begin to suggest terrible things, and with every passing minute, it becomes harder to tell whether the danger is coming from the person holding the instruments, or from something happening inside the patient's own body. Inspired by the real possibility that systemic infections can leave clues in the mouth, Just a Little Wider is an immersive work of medical horror in which illness, perception, and reality become impossible to separate. 💀 Month of the Macabre 2026 — An original Infectious Dose horror story. 🎬 This week's #SickFlicks: Dead Ringers (1988) and The Autopsy of Jane Doe (2016)—two unsettling films about medical authority, the vulnerability of the human body, and exams that take a horrifying turn. 🎧 Headphones recommended.

The museum is closed. The exhibits aren't finished changing. In the first episode of Month of the Macabre 2026, a routine after-hours visit to a museum of infectious disease history takes an unexpected turn. Past the familiar scenes of Broad Street, the 1918 influenza pandemic, and SARS in Toronto, a new gallery has appeared: a modern train station displaying an outbreak that hasn't happened yet. Then the exhibit changes. And changes again The Collection is an immersive Infectious Dose audio story about infectious disease history, transmission, outbreak investigation, and what happens when knowing the future doesn't necessarily mean you can control it. 🎬 This week's #SickFlicks to accompany the episode: Annihilation (2018) and The Endless (2017)—two stories in which reality begins behaving according to unfamiliar rules, leaving the people inside to figure out what those rules mean.

It’s horror movie night, but Heather can’t stop seeing infectious disease in the monsters. Heather is joined by her friend Valerie to explore the real biology behind some of horror’s most enduring fears: tuberculosis and vampire lore, rabies and werewolves, zombies as outbreak epidemiology, neurological disease and possession, and the strange biology behind The Last of Us, The Thing, and Alien. Plus, Valerie plays the hilarious Horror Movie or Medical Literature? and discovers that when it comes to horror, evolution has had a considerable head start. So grab a drink, pick a movie, and remember the most important public-health lesson horror has apparently failed to teach us: stop hiding bites.

How do eight people get falciparum malaria in Germany when none of them traveled somewhere malaria is circulating? The answer may be that they didn't have to travel. The mosquito did. This episode follows the investigation into a cluster of malaria cases linked geographically or occupationally to Frankfurt Airport, including three deaths. We'll look at how an infected mosquito can carry malaria across continents, why airport malaria can be difficult to diagnose, what previous cases tell us about this rare phenomenon, and what investigators still don't know about the current outbreak.
