I seem to have seen a lot of posts where households are "self isolating" and therefore feel they are "safe" after 14 days. Does this mean you've had no contact at all with the outside world? No shopping, no exercise, no post or deliveries? How?
Social distancing (which is what has been asked of most of us) is something else. It's not intended to elliminate all risk of infection, for most indviduals the risk from catching the virus is low. Social distancing reduces the rate of spread to protect the NHS. That is all, it doesn't give individuals any guarantee of protection and it's not designed to.
