Disease Surveillance

The Douglas County Health Department conducts disease surveillance to control the spread of communicable (contagious) disease. These diseases can be spread in a variety of ways: person to person, contact with animals, or eating contaminated food and water. This includes serious diseases such as E. coli, Salmonella, and rabies.

Illnesses are reported directly to the Douglas County Health Department and discovered through investigations. Communicable disease staff conduct interviews and investigations to learn about disease transmission and prevent further illness in Douglas County.
