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.

In Oregon, some of the most common pathogens that cause disease outbreaks are Salmonella, ShigellaE. coli, and norovirus. Outbreaks of pertussis, gastroenteritis, and measles still occur. Mumps is now a reportable disease in Oregon. Physicians are required by law to report suspected outbreaks of specified diseases, infections and conditions. ​
