Animal Contact Outbreak Surveillance System
CDC’s Animal Contact Outbreak Surveillance System (ACOSS) collects information from state and local health departments about outbreaks of human enteric illness linked to contact with animals or their environments.
Animal contact outbreaks provide important insights into the way germs spread from animals to people. They also help us understand which germs are linked commonly to which animals, and how we might prevent illnesses.
