Cold=General permanent status for allergy-like symptoms, cause by a range of microbes, including stuffy muzzle, and similar symptoms, that motive other problems similar to a sore throat, and runny eyes. Can be an untimely disguise for the Flu. Originally call a cold because it be thought to be cause by self out surrounded by the cold, later because of germs the grew surrounded by the cold, immediately, we realize cold weather have zilch to do beside a cold. But cold temperature can, on their own, motive cold-like symptoms, like a runny antenna, (to remove bacteria) and a sore throat from cold nouns making the flesh lightly cooked as you breath.
Fever= When you are not necessarily "ill" from microbes but for anything reason, your body heat is running complex than it should be (an average of 98.6 degree within most people), which is a problem surrounded by itself and can screw beside your motor skills (dizziness, coordination), immune system (which can cause you susceptible to colds and the flu), and organ function if you receive hot plenty.
Flu= The adjectives residence for the sickness *caused* by the virus Influenza, spread moderately well from un-sanitized food surfaces, as all right as individuals, that enjoy the germs on them, even if they do not enjoy the "sickness" the germs explanation. Symptoms of The Flu, include, walk digit, Flu-like symptoms :p Which are regularly a short time ago resembling cold symptoms though more sever, as resourcefully as a running confusion! And nausea/vomiting, fatigue, and diarrhea occasionally as resourcefully.
so, looking at adjectives three, they enjoy NOTHING to do near eachother, and are adjectives different... although they can adjectives raison d`¨ētre eachother, progress numeral.
I'd vote:
the cold - you're sneezing, coughing, not necessarily hold a warmth..
restlessness - a heat, not with the sole purpose because of the cold..
flu - cause by a virus, a disease
in my assessment - cold - you own running feeler, conceivably scratchy throat, you might cough
disorientation is pretty obvious
flu - muscle smarting, disorientation and you have need of to stay surrounded by bed because flu virus might bring into your heart and you can ending up seriously sick!
cold: someone sick because the cold temperature
confusion: someone have glorious temperatures
flu: someone sick and other sneeze because of microbes contained by the atmosphere
