Because they don't understand what the numbers they hear actually mean.

First, they incorrectly assume that every single person who catches the coronavirus has been counted, which leads to an accurate mortality rate. The mortality rate is based on the people who were sick enough and died almost enough to be tested for.

Next, they don't understand what type of person is initially susceptible to the virus. You see people who show that they don't understand math at all by saying, "Just multiply the population * 0.034 to find the number of people who will die."

People who are initially in poor health or the elderly will die. The death statistics do not "increase" for these people, they are the death statistics. The boys will be fine and the boys and healthy people will not be tested.

If you really understand what the virus really is, you will find that the mortality rate is significantly lower than stated. It is just a cold virus, which is more likely to cause deep pneumonia.

As for the corona virus, it is very easy to transmit from person to person. This is really the only "pandemic" problem here. It transmits very easily.
