From my laymans knowledge if you think of the 60% of people with general immunity rather than anti body immunity.
So say 25% of people gain antibodies but a further 35% have natural immunity via t cells, immunity from other coronavirus (such as common cold). You could get to 60% without ever knowing you had 60%.
Will be good news if that is the case. Yet I fear even if/when we get more evidence of this people are already paralysed into fear. Plans are being made for the 'new normal', people confidently predicting that we won't have crowds or sporting events for years, newspaper headlines proclaiming Germany's rises cases (they're decreasing)….. its nuts.
My company has gone completely mad.... We have been working throughout (with distancing) and now suddenly there are notices on computer logins, massive "stay alert" notices on the desktops, one way systems to enter our chemical stores....totally bonkers.
