From Binet's work the IQ scale called the Binet Scale, (and later the Simon-Binet Scale) was developed. Sometime later, intelligence quotient, or IQ, entered our vocabulary.
Tuberculosis (TB) is an infectious disease that usually attacks the lungs, but can attack almost any part of the body. Tuberculosis is spread from person to person through the air. When a person with TB in their lungs or throat coughs, laughs, sneezes, sings, or even talks, the germs that cause TB may spread through the air.
Tuberculosis bacteria are spread from person to person through the air. The bacteria are in droplets of secretions that come out of your mouth or nose when you cough or sneeze. One-time exposure to someone with tuberculosis is not likely to cause infection. Repeated or prolonged exposure is usually necessary.
