Delta is a type of fibre that transmits signals that are interpreted and perceived as pain.

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.

Egyptians were smarter about things when is came to illnesses. I believe that is would be action as in them doing something to be sick or getting hurt. Other wise if you are talking about the "occurrence" of a season or something like that. they believed that illnesses can be caused by a variety of different things. like eating certain foods or drinking contaminated water. They also to believe that gods have something to do with illnesses. All in all I think the answer you looking for is action.
