TB EVALUATION AT TODD BEAMER HIGH SCHOOL

Public Health – Seattle & King County is following up on the report of a Todd Beamer High School community member who was diagnosed with active tuberculosis (TB). Public Health is working with the high school and Federal Way School District officials to define the extent of any potential TB exposures, conduct evaluations for those exposed, and provide guidance and information to the Todd Beamer High School community.

TB is not easy to spread

TB is an infectious disease caused by bacteria that are passed from person to person through the air. TB is not easily spread; it’s much harder to spread than the cold or flu. It typically takes repeated and prolonged exposure in a confined indoor space to become infected with TB. Even in households with a contagious TB case, only about 1-in-3 close household contacts become infected.

Details on the evaluation
As a precaution, twenty people from the school community are recommended to be screened for TB, based on the amount of time they were exposed to the person with TB in indoor spaces. Public Health will be directly contacting individuals who may need further evaluation. If you are not contacted by Public Health, you are not considered to be exposed, and no action is required.

Active TB vs. latent TB infection
Unlike active TB disease, people with latent (or dormant) TB infection can’t spread it to others and are not ill with the disease. Approximately 100,000 people in King County have latent TB infection. While they aren’t contagious now, they could potentially have active TB in the future and also infect others. Approximately one in 10 people with latent TB infection will develop active TB in their lifetime.

Treatment for TB
The person at Todd Beamer High School with active TB disease is receiving treatment, and is currently not a risk for infecting others. Most cases of active TB are readily treatable with antibiotics that are commonly available; treatment typically takes six to nine months.

To become cured, a patient must complete the entire treatment, even after they are no longer infectious. If the treatment is interrupted before the bacteria are completely eliminated, TB can develop drug-resistance and become much harder to treat.

People at Todd Beamer High School who are identified to be infected with latent TB infection may be recommended for treatment, so that they do not develop the disease in the future. Latent TB infection can be treated in 3-4 months.

More about TB
TB usually affects the lungs, but can affect lymph nodes, bones, joints, and other parts of the body. A person with active TB in the lungs can spread the disease by coughing or sneezing. In King County, 97 new cases of TB disease were reported in 2017. On average, two cases of TB disease are diagnosed in King County each week.

TB program protects the community
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.

TB is a global threat, with over two million deaths every year, as people in many parts of the world do not have access to treatment and effective TB control programs like we do in the United States. Because we are at a global crossroads in King County, we need to be constantly vigilant to prevent the spread of TB.
