The truth that younger and healthy people of their 20's, who agreement the disease, die.
The fact that aged individuals over the age of 100 years have recovered from the Coronavirus.
The fact that there are those who settlement the ailment with out even feeling it.
The fact that there are people (no longer many) who recovered from the Coronavirus and shrunk it again.
The truth that a few scientists agree with that there can be two strains to the disease, one moderate and one extra competitive.
These cases ought to lead, even individuals who are not experts within the area, to the belief that there's any other influential chance aspect. This element can certainly be, as described below, the level of exposure to the Coronavirus, or, in different words, the wide variety of viruses to which the frame is uncovered.
The frame's immune system is similar to a countrywide army. The younger and healthier the individuals, the more potent their army. When foreign and opposed viruses invade the body, soldiers of the immune device immediately mobilize to protect it. The assumption through which healthful human beings, and not using a heritage ailments, can triumph over the virus, is primarily based simplest at the exceptional of their immune gadget, but does no longer don't forget the quantity, i.E. The numerical balance of energy among the number of immune device cells and the quantity of the attacking viruses. To higher understand the extent to which publicity to the virus can be vital, we are able to gift two examples of contraction - one with the aid of a healthful young man or woman who hung out with Corona sufferers for several days without preserving a distance, and the opposite, a healthy young individual who only touched a surface several hours after it changed into uncovered to the virus. Clearly, the immune machine of the person uncovered to a "small" number of virus cells can overcome them more without problems than the immune system of an character uncovered to a miles larger quantity of the virus cells.
A special exposure level to the Corona viruses can provide an explanation for why aged human beings with background diseases recover from the virus, why younger and healthy individuals die from it, why humans experience the disease with out feeling any signs and symptoms and why human beings, who are uncovered to a very low degree of the virus, fail to broaden sufficient antibodies and settlement the disease once more. This also explains why there are scientists who believe that there are two strains to the disorder, one moderate and one very violent
