An inmate in the King County Jail system was recently diagnosed with infectious tuberculosis (TB). The person came into contact with other inmates and staff at times between November 20, 2016 and March 1, 2017, mostly at the Maleng Regional Justice Center in Kent. Public Health – Seattle & King County’s TB control program has been notified, and is working with Jail Health staff as they identify and screen exposed individuals.
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, Public Health staff identified individuals who may have had ongoing exposure to the person with TB. At least 66 inmates with ongoing exposure were identified; staff exposures are currently being determined. These people are being screened to determine if anyone has symptoms of active TB, as well as getting TB tests to
The patient in the King County Jail 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. Drug-resistant strains require different antibiotics and may include a longer course of treatment (up to two years).
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 who are identified in this investigation to be infected with latent TB may be recommended for treatment, so that they do not develop the disease in the future.
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, 98 new cases of TB disease were reported in 2015. 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.
