I can only assume that what is happening now would happen on a much larger scale.
I know some parents who refuse to test their children, and some which do it sporadically.
In our town, our children have been back at school for 3 weeks, first week we had a small jump in cases in the town, second slightly bigger jump. 3rd week we have about 200 cases more in a 7 day period than we did 3 weeks ago. This is with over 90,000 tests being completed in our town within a week. If those tests weren't being completed, we wouldn't know, no one would self isolate, and it would spread like wildfire. Its spreading now, but some people having the knowledge they have it is meaning they're isolating and not continuing to be around the wider community.
My concern is keeping the level of normality where it is and trying to move forward to look forward to other things we haven't enjoyed. I think testing is an integral part of that.
If there wasn't a focus on testing, I can only imagine how many people with less severe symptoms would write it off, how many employers would lose understanding of their employees? I bet there would be a few saying, you don't know its covid, it's probably just a cold. You have to come in.
Before we know it, it would be essential masks, lockdowns, school closures and no chance of foreign travel on the horizon again.
I personally don't mind wearing a mask, I find it helps me feel safer, but I certainly don't want to see these restrictions imposed on people who don't want them. Surely testing is a decent compromise?
