The Oregon Alliance Working for Antibiotic Resistance Education (AWARE) is a statewide coalition that promotes the appropriate use of antibiotics to reduce the likelihood that bacteria will become resistant to them.

Emerging Infections Program

Oregon participates in this effort, led by the federal Centers for Disease Control and Prevention (CDC), with 9 other states to explore communicable diseases of current public health concern and newly emerging infections. These data help estimate the extent of the problems and provide a starting point for studying risk factors and developing better strategies for prevention and control.

Healthcare Associated Infections (HAI) Program

The HAI program works to understand and prevent infections associated with healthcare settings through measurement and reporting of selected infections and associated medical procedures.

NW Center for Foodborne Outbreak Management, Epidemiology, and Surveillance (FOMES)

FOMES is a program that fosters the public health practice of foodborne and diarrheal disease surveillance and outbreak investigation. FOMES is a collaboration between the Oregon Public Health Division, Oregon Health Sciences University and the University of Minnesota.

About Us

We work with local health departments, other states and the Centers for Disease Control and Prevention (CDC) to prevent and control communicable diseases and outbreaks of acute diseases in Oregon.

Acute and Communicable Disease Prevention is part of the Center for Public Health Practice.

Read More

We assist local health departments with disease investigation and control and investigate outbreaks with local health departments, neighboring states or the CDC.

We conduct surveillance on diseases of new and increasing concern and collect, analyze and publish reportable disease surveillance data to guide public health policy.

We also provide guidelines about preparedness and response to a bioterrorism event or natural pandemic, educate patients and clinicians about the spread of antibiotic-resistant bacteria, develop electronic disease reporting networks and approve alternative methods of infectious waste treatment.
