Public Health 202D Seattle & King County has confirmed an active case of tuberculosis connected to Rainier Beach High School in south Seattle. The person with TB is already receiving treatment and is not considered contagious while health investigators work to figure out who else may have been exposed. As a precaution, officials are recommending that about 130 people linked to the school get evaluated for TB.
Officials: Who Will Be Tested and How Outreach Works
As reported by KIRO 7, Public Health says Rainier Beach will directly reach out to anyone who needs a medical risk assessment and TB test. The department is focusing on people who spent repeated time indoors with the person who has active disease so that testing targets those at highest risk. Investigators are working with school leaders to schedule evaluations and arrange follow-up care for anyone who needs it.
How TB Spreads and What To Watch For
According to the CDC, TB bacteria spread through the air when someone with active pulmonary TB coughs, sneezes or talks, and it usually takes prolonged, close contact in enclosed spaces for infection to occur rather than quick, casual contact. The CDC notes that latent TB infection does not make a person contagious, but it can develop into active disease. Common warning signs include a cough that will not go away, fever, night sweats and weight loss. Anyone with these symptoms is advised to contact a health care provider promptly for evaluation.
Testing and Treatment Steps
Public Health reports that most active TB cases can be treated with commonly available antibiotics, with treatment typically lasting six to nine months, as noted by KIRO 7. King County's TB Control program offers testing and case management, and the county lists a TB control phone line at (206) 744-4579 for anyone seeking guidance. Families who have not been contacted but believe they may have been exposed are urged to call Rainier Beach's main office at (206) 252-6350 or the county TB line to discuss next steps.
Context: School TB Clusters Are Uncommon but Scrutinized
School-centered TB clusters are relatively rare, but public health teams sometimes launch wide testing efforts after a single active case. Health officials in San Francisco, for example, recently identified hundreds of latent TB infections during an outbreak at Archbishop Riordan High School earlier this winter. That situation highlights why quick contact investigations, targeted testing and timely treatment remain central strategies for limiting spread and keeping schools operating safely.
Public Health will continue its contact investigation at Rainier Beach and share updates as more information becomes available. Families with questions are encouraged to watch for outreach from the school and to contact the county TB line or the school office if they need more details or support.
