Show me your graph on death rate for ages 0-20. Showing us the # of cases per day is useless and testing seems to vary from state to state. Some testing has even been reported as generating false positives...so how much of this data is "real?" Let's base our decisions on more specific data. The virus isn't going anywhere until there's a vaccine and death rates have already plummeted indicating that it's weakening. Speaking of data--with # of cases increasing in Greenville Co. @ roughly 530,000 folks, the overall death rate is a whopping 0.0179% with only 6,227 (1.17%) being infected with Covid-19.
Are you willing to hold these kids out of school for another 3 months knowing the negative, long-term impact it would have? Widespread job and income loss....economic insecurity among families would likely increase number of child labor rates....sexual exploitation, teenage pregnancy, etc. The stresses it puts on families, particularly those who live in tight quarters and have been pent up for months, are increasing the number of domestic violence cases. Keeping them at home will also cause a large number of them to continue being vulnerable to exploitation and abuse. I haven't even mentioned the malnourishment some of these kids are receiving by staying at home. But hey, let's stick with your "scientific data," right?
Where is your data supporting your argument that the virus is weakening?
Also, the stay at home measures we have endured did impact death rates and other measures for the positive. Now that those are no longer in place to a large degree, new data in August will tell the story.
