  • One confirmed TB case at Rainier Beach High School triggered precautionary testing for about 130 exposed students and staff members.
  • TB requires prolonged indoor contact to spread; the infected person is now under treatment and no longer contagious.
  • King County averages two TB diagnoses weekly; public health screening aims to prevent further transmission and outbreak escalation.

Active TB Case Prompts Precautionary Response

More than 100 people associated with Rainier Beach High School are being tested for Tuberculosis (TB) after one person was diagnosed and is now getting treatment for the serious, airborne disease. As a precaution, Public Health is recommending that about 130 people in connection with the south Seattle school be evaluated, based on the amount of time they were exposed to the person with TB in indoor spaces.

The person with tuberculosis is now receiving treatment and is no longer contagious. Public Health is working with Rainier Beach High School to define the extent of any potential TB exposures and supporting the school as Public Health conducts evaluations for those exposed and provides guidance and information to staff, students and families.

Understanding Tuberculosis Risk and Transmission

TB is not easy to spread-- it's a disease caused by bacteria that's passed from person to person through the air. Unlike COVID or the flu, it takes repeated and prolonged exposure in a confined indoor space to spread. Even in households with one person who is contagious with TB, only about 1-in-3 close household members become infected, according to Public Health.

Most cases of tuberculosis are treatable with antibiotics, with treatment typically taking six to nine months. A person with active TB in the lungs can spread the disease by coughing or sneezing. The health department has identified those who need testing based on prolonged indoor contact with the infected individual.

Student Reactions and School Response

The news caught many students off guard, bringing back memories of pandemic precautions. "Today, I was thinking, 'Should I just stay home?'" RBHS Senior Anton Duro told KOMO News. "People are coming to school with masks now. It's really weird to me. It's like Covid all over again."

"Our priority is to care for and support the Rainier Beach community during this time," Seattle Public Schools Chief of Staff Bev Redmond wrote in a statement. "We will continue to partner closely with PHSKC and remain committed to keeping the Rainier Beach school community informed as this process moves forward."

Broader Context and Prevention Efforts

In King County, 110 new cases of active TB disease were reported in 2024. On average, about two cases are diagnosed each week. The last time King County had a case of active TB associated with a K-12 school was in 2023.

Public Health – Seattle & King County's TB Control Program ensures that people with active TB are diagnosed and cured, and that others in contact with them who are at highest risk of infection are screened, so that infections do not spread. This essential public health work improves the community's health and saves money by controlling the spread of TB, preventing outbreaks, and preventing the development of multi-drug resistant TB that can be very expensive to treat. The rapid response demonstrates how public health systems work to contain potential outbreaks before they can spread throughout school communities.
