The Oregon Health Authority (OHA) is publishing data on COVID-19 cases associated with schools that offer in-person instruction. This is to inform the public of potential COVID-19 exposure and to provide transparency surrounding COVID-19 in schools. School is defined as any place of learning for student in kindergarten through 12th grade, or a subset, with at least 30 students enrolled. This includes but is not limited to: public school, private schools, parochial and charter schools. Staff is defined as any person who works at the school regardless of their position. Staff include any person who are working part-time or full-time at the school. Volunteer is defined as any person who volunteers onsite.
Beginning with the September 22, 2021 report:
- OHA will continue to report the number of cases in school by student and staff/volunteer. Active and resolved outbreaks will now include all cases linked to the outbreak and will no longer differentiate between student and staff/volunteer cases.
- K-12 outbreaks are defined as having 2+ cases identified, where there is evidence of transmission, at school. Outbreaks may include cases who were not at school but are close contacts of those exposed at school. This provides a more accurate picture of the scale of K-12 related outbreaks and how they may link to other cases in the community.
Note: To protect the privacy of those involved, no names will be released. Data are provisional and subject to change as additional test results are received and public health investigations proceed. Please refer to the
September 30, 2020, Memo to School and District Leaders for more details.
