*Campylobacter* bacteria were first linked to animal diseases in the early 20th century. Its recognition as a significant human pathogen causing diarrheal disease gained prominence in the 1970s, leading to its identification as a leading cause of foodborne illness worldwide.
The main routes of transmission are through consuming contaminated food, especially raw or undercooked poultry, unpasteurized milk, or untreated water. Contact with infected animals (e.g., pets, farm animals) or their feces is also a common source, and person-to-person spread is rare but possible.
Contagious Period: Varies by disease
