Supermarkets vary by size, some mini-marts are also referred to as supermarkets although I doubt they are what people first think of.
There was an article in the Health Service Journal yesterday which suggested that Health Staff are far more at risk in enclosed rest areas and coffee rooms than they are in their work locations. In part due to the enclosed environment, but also because staff don’t wear PPE or take extra precautions in rest areas.
We know that Transmission of coronavirus is already significantly higher indoors compared with outside, and higher still, in small enclosed rooms where people are in close proximity.
We also know that measures like social distancing, Appropriate PPE and good hygiene help to further prevent the Spread of infection.
So now large airey supermarkets offer better protection than pokey offices, especially with the additional measures in place.
During the prelockdown madness though, the crowds could have increased the risks to supermarket workers, especially those in more vulnerable groups.
Sadly, some supermarket workers have lost their lives, most likely after contracting the disease before adequate measures were in place to minimise spread (and also from other non-work environments). The risks of acquiring coronavirus are now much lower and the risks of dying, lower still.
