The process of infection can be broken down into stages, each of which can be blocked by different defense mechanisms. In the first stage, a new host is exposed to infectious particles shed by an infected individual. The number, route, mode of transmission, and stability of an infectious agent outside the host determines its infectivity. Some pathogens, such as anthrax, are spread by spores that are highly resistant to heat and drying, while others, such as the human immunodeficiency virus (HIV), are spread only by the exchange of bodily fluids or tissues because they are unable to survive as infectious agents outside the body.
I would advise you do more research on .gov websites. But I don't believe they will take anything other than a State I.D.
WHAT WHY IS ZHE SOOOO LONG??

A person with
Parkinson’s disease losses cells that
produce norepinephrine, which causes the nerve endings to
produce several of the non-motor features seen in person with Parkinson’s disease
including fatigue and abnormalities of blood pressure regulation.
In addition, norepinephrine is important for regulating the activity of dopamine
neurons and when the dopamine neurons start dying, the norepinephrine neurons send
signals to the surviving dopamine cells to dramatically increase their activity
and the output of dopamine as to ameliorate the symptoms of Parkinson's disease.</span>
