Dr. Pritt started her blog after she completed her fellowship at Mayo Clinic in clinical microbiology. She attended the London School of Hygiene and Tropical Medicine to study parasitology for one year. During that year in England, Dr. Pritt saw some amazing cases, which she shared with her colleagues back at Mayo through her blog.
