I would like to shed a little light on the wastewater testing. Back in 2020 when they locked everyone down and sent all students home, my friend's granddaughter got to stay in her dorm and attend college classes with everyone else in her college. The college began testing the wastewater of the dormitories. If they found it they could isolate those people only for several days while they could go online. That is how the college was able to remain open by keeping covid cases to 52 or less on campus. Test the wastewater and isolate that group if they find it. It was months before the newspapers would write about it. Of course they wouldn't, it would be a way for everyone to be open again and test the wastewater. So now they do that while everyone has forgotten and people think they're being crazy. It is a good way to find it or anything bad and isolate those and you never have to lock down a country again! No college should ever have to send students home again!
