LATELY, we have read about/heard numerous complaints about supermarkets denying entry to customers who aren’t wearing masks. This is a wise move by the managements of supermarkets, as the latest recommendations by the US Centers for Disease Control is that people should wear masks in public, especially where social distancing is not possible.
The rationale is that some people can test positive for Covid-19 but do not develop symptoms. During this asymptomatic period, these infected people can be contagious. There-fore, if everyone wears a mask, we can protect one another, reducing overall community transmission.
