The Typhoid Files

by Ruth Redford, Jake Hill (Illustrator)

Overview

In the early 1900s, everyone from scientists to sanitation workers were working to crack a true medical mystery--who was spreading typhoid fever in community of Mamaroneck, New York?

All signs pointed to servant Mary Mallon, but could she spread the disease without showing symptoms herself? Marnie and her trusted AI sidekick Glitch are on the case, following the clues to learn the history of typhoid fever, how it spread, and how we're protected from typhoid fever today. Science enthusiast Marnie discovers the fascinating history of this disease while going above and beyond, as usual, for her research project. A fun, graphic novel approach, diverse characters, and humorous text tell this thrilling story of medical history in a high-interest format.

Marnie's Medical Mysteries was developed in collaboration with Nipunie Rajapakse, M.D., Pediatric Infectious Diseases Physician at the Mayo Clinic Children's Center. She completed a Master of Public Health at the Harvard T.H. Chan School of Public Health and previously worked as a consultant with the World Health Organization.
