The data is similar to the data for the fatal Wuhan Virus cases everywhere. Many folks may get infected, but those most in danger of that infection being deadly are not 80-90% of the population. It is the folks who are already not healthy due to long running poor health conditions and/or cancer treatments done not so long ago. Children especially have not been affected much at all and never should have had their schools shut down. That has been a particular disgrace.
Children do not live on a children’s island. They have parents and teachers, who may have preexisting conditions.
Many of the preexisting conditions, such as hypertension or overweight, do not mean a person is sickly or likely to die in the next ten or twenty years.
These preexisting conditions are very common.
