The Typhoid Files

In the early 1900s everyone from scientists to sanitation workers were working to crack a true medical mystery--who was spreading typhoid fever in well-to-do Mamaroneck, New York? All signs pointed to domestic servant Mary Mallon. But could she spread the disease without showing symptoms herself? Maisie and her trusted AI sidekick 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 Maisie discovers the fascinating history of this disease while going above and beyond, as usual, for her research project.

A fun graphic approach, diverse characters, and humorous text tell this thrilling story of medical history in a high-interest format.

Maisie'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.
