So 2 people got Covid 19 at the Gateway Superstore, how when everyone has to wear masks? I'll tell you how, we are expanding our click and collect at all stores and the construction guys aren't wearing masks, nice eh . Turns out one employee and one construction guy are infected, gee i wonder why.
How? Well let's consider some possibilities.
The first possibility is that they were independently infected elsewhere and being in the same workplace is just coincidence.
Barring that, let's consider the likelihood of transmission within the workplace. In general, construction areas are off limits to non-construction people for the purposes of safety and insurance compliance. There should be no reason why your co-worker would be anywhere near the trades people for extended periods.
So, I have to ask... are they both smokers? Cause right there I see the big red flags. Smokers tend to congregate, even if they don't know each other. It's that kindred spirit, us against a world that hates us thing. And think about it? What do smokers do? They expel their breath long distances after taking a puff, much more than if you are breathing out normally. So, a 2 metre separation may be adequate under normal circumstances but not when you're near somebody going phoooosh with every second breath as they try to cram as much nicotine into their systems in the short time they're allotted for their smoke breaks.
