Unfortunately messages from government have been weak and a lot of downright false information has been spread from unreliable sources.
I have had a lot of customers (and friends) telling me that it's ok to have a non - essential visit because they feel ok and I feel ok so there's no danger. This appears not to be the case.
According to this article in New Scientist (apparently a real scientific journal) I was sent by my daughter (she's much smarter than me) it could be 10% of people with the virus show no symptoms but can spread the virus to (and potentially kill) their friend and family (and customers!) "asymptomatic spread" by non - essential visits.
"..Even though these people were only 55 per cent as contagious as people with symptoms, the study found that they were the source of 79 per cent of further infections, due to there being more of them, and the higher likelihood that they were out and about.."
