Downloaded the latest database from Ohio Dept. of Health.
It contains 28 entries of persons 19 or under dying of COVID.
Out of 26,914 in the 0-19 cohort.
So the statement that there have been no deaths in that cohort is not true.
How many of those young persons had serious pre-existing conditions?
The CDC data shows no deaths for anyone under 24 in Ohio.
