When someone is found to have active, communicable tuberculosis for 19 years, what does that mean exactly? Were they contagious for 19 years?

In most people who breathe in TB germs and become infected, the body is able to fight the TB germs to stop them from growing. The TB germs become inactive, but they remain alive in the body and can become active later.
