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 Causes. All cases of TB are passed from person to person via droplets. When someone with TB infection coughs, sneezes, or talks, tiny droplets of saliva or mucus are expelled into the air, which can be inhaled by another person.
