Sadly the only answer will be total lockdown. This is because some people simply do not understand how viruses transmit. It's really about lack of education and/or intellectual ability to think beyond the obvious.
They justify AND believe what they are doing is 'fine' because they simply aren't smart enough to understand. I blame the Govt for assuming large numbers of our population have more basic brain power than they actually do. It's all very well for scientists and government ministers to assume people can work it out for themselves but if you have a large section of the population with below average intelligence then they simply won't get it. Take the post by Helga ;
and am not apologising for seeing my 2 adult DC for an hour in MY HOUSE. We are middle aged, and they are in their 20s, and have no children. We also saw no elderly people yesterday.
You see, she genuinely thinks she was acting safely. She saw her adult DC 'in her house' .. she thinks that as she has been keeping to herself and not going outside to visit her DC that she is safe. (She completely misses the point that her DCs could both be infected and have now bought that in to her home) . She goes on to mitigate this 'unnecessary social contact ' (as clearly expressed by the PM) by saying they didn't come into contact with any elderly people. The problem is that she hasn't worked out that as her DC 'young professionals' and DH are still working, the DCs could have passed it to their dad yesterday and dad then pass it to an elderly person either at work or on way to work during the next week. This then becomes a spread that didn't need to happen. However because a lot of people lack the ability to follow the train of thought you will get more and more of a spread.
Me and DH are no more likely to get coronavirus from seeing them for an hour in our HOME, than we are from going to the shops, or from DH going to work and mixing with 100s of people and then coming home.
Again, Helgahelga can see no connection between 'existing risk' (DH going to work with 100s of people' ) and the unnecessary addition of her DCs effectively doubling the sources from where the risk will come.
I am not going to call this OP names. However I am concerned that the likes of Helgahelga are to be found all over the country and the lack of clear rules will make this epidemic much worse.
I worked in a developing country for many years in public health. One of the first things we learned was that containment of an epidemic (our main issues were cholera and TB) HAS to be imparted in a way that the most intellectually challenged can understand.
