Learning Diability (LD) is a neurological disorder that is usually diagnosed in childhood. Nearly 5% of students in public schools have been identified to have LD. The cause or causes of LD have not been clearly defined, although genetics or exposure to toxins have been implicated. LD can be diagnosed through standardized testing of aptitude and achievement. Treatment of LD requires special provisions in schools to provide special educational accommodations in order to utilize the strengths of the learning disabled to assist them in learning.

The human immune system has a memory. As the body is exposed to a disease-forming organism, the immune cells (called lymphocytes) are activated, reproduce by cell division, and attack the offending organism. Some of the newly formed lymphocytes remain indefinitely in the body as memory cells. This process usually takes several days to complete. Therefore, an infectious microbe can cause much damage by the time the immune system has had time to react to, keep in check, or destroy it. For certain microbes, such as Diphtheria, Tetanus, and Polio, several days are enough to cause severe debilitating damage or death.
