Outbreak Investigation in Oregon
cell phone

Call your local county health department if you suspect an outbreak of disease.


The Oregon Health Authority, Public Health Division's Acute and Communicable Disease Prevention program works with Oregon county health departments, other states and the CDC to detect, track, prevent and control the spread of infectious diseases.

Physicians are required by law to report suspected outbreaks of specified diseases, infections and conditions. In Oregon, some of the most common pathogens that cause disease outbreaks are Salmonella, Shigella, E. coli, and norovirus. Outbreaks in healthcare facilities, including hospitals, nursing homes, ambulatory surgery centers, dialysis centers, birthing centers, and community-based care (assisted living, residential care, foster homes), are reportable.​​
