raamdonk said "I get the desire for everyone to be tested, but I really question what an individual is going to do differently based on the test results? If you're symptomatic - stay home until you feel better. If you've been told to isolate - you should be doing that. If you're asymptomatic - why are you getting tested in the first place as the chances of false negatives are far higher anyway. "
It makes a world of difference for isolation and contact tracing.
I read somewhere (maybe it was rules for school for a different jurisdiction, I'm pretty sure it's not Manitoba?) that if you have a negative COVID test, you can come back to school once your symptoms resolve, but if you have a positive test (or no test at all), you need to wait 14 days from onset of symptoms before ending isolation.
It would also make a difference for others in your household, and this would apply in Manitoba. If you have a positive test, unless you have been isolating from others in your household, your entire household will also need to isolate for at least 14 days, possibly more depending if anyone else in the house gets sick. So if you get sick, but didn't isolate from others in your house and someone else gets sick at day 12, your 14-day clock will restart. And it will have to keep going until it's run it's course in your household, or you've gone 14 days with no one else getting sick.
I sure would want to know for sure if it's COVID or not in that case. I have 7 people in my house. If we get it one at a time (unlikely, but possible, we'd likely be staggered in groups), we could have a 14-week quarentine block. I don't want to do that unless I have to!
