Defamation Law: The Basics. There is always a delicate balance between one person's right to freedom of speech and another's right to protect their good name. It is often difficult to know which personal remarks are proper and which run afoul of defamation law.
What Causes TB. Tuberculosis is an infection caused by bacteria. It's spread through the airâwhen an infected person coughs, sneezes, laughs, etc. However, it is not easy to become infected with tuberculosis. Usually a person has to be close to someone with TB disease for a long period of time.
Tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air. This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings. Although tuberculosis is contagious, it's not easy to catch.
