Communicable Diseases are illnesses which are caused by pathogens or microorganisms, e.g virus and bacteria, that are transmitted from one person or animal to another in different ways. It can spread through contact of body fluids or blood, sexual contact, contaminated food and water, or through air.
With the advancement of medical science, different ways of controlling communicable diseases have emerged throughout the centuries and have been proven to lessen the mortality rate as time passed.
One is the development of Immunization. Immunization; to make one's body immune to a certain disease so it will be easier for the body to combat with the pathogens in contact with it. Until now, production of Immunization is still being updated depending upon the diseases that are currently affecting the majority. The development of immunization has given medical science, then and now, a very big impact in controlling diseases. How does it work? Immunization boosts the body's natural immunity whenever microorganisms enter the body. The body identifies these microorganisms as foreign elements, thus releasing certain kinds of cells to help fight off the infection.

The purpose is to not have to do mouth to mouth CPR (conventional CPR)
Explanation:
Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.
<h3>
Delta fibres</h3>
A delta fibres (also known as A fibres) are a type of sensory fibre. They respond to cold and pressure stimuli, and as nociceptors, their stimulation is perceived as fast/first pain input. Because they are thinly myelinated, they transmit impulses quicker than unmyelinated C fibres but slower than other, thicker myelinated "A" class fibres.
Structure
They have myelinated axons that are thin (2 to 5 m in diameter) and have a moderate conduction velocity, or speed at which a nerve signal moves (2 to 30 m/s). These nerve fibres make up the afferent portion of the reflex arc that causes the body to "draw away" from noxious stimuli because they are linked to acute (sharp) pain (e.g. retracting your hand away from a hot stove). A part of A fibres is also linked to pressure and temperature perception (also known as "cold receptors" in mammals). Contrarily, slow-conducting, unmyelinated C fibres convey gradual, scorching pain.
