On October 23, King County Superior Court in Washington issued an order for home detention and treatment of a potentially contagious individual infected with tuberculosis (TB). TB is treatable with antibiotics, although the treatment generally lasts for months and may start with an isolation period to prevent the spread of the disease, which can be threatening and challenging to infected patients. This particular patient completed his initial TB treatment at the beginning of 2015, but failed to reliably continue to take medication after leaving home isolation, increasing the risk that the bacterium he was carrying might develop resistance to the treatments. To convince him to continue treatment to improve his own health and protect the community, it became necessary to take more drastic steps than usual. While court action is a rare occurrence, it also highlights the ongoing, active role of Seattle & King County’s TB control program.
