More About Covid on Surfaces

 When I spoke recently on the chances of catching the Covid virus from a surface I was wrong when I said that the Godman study was the only one.   Many studies recently have filled the pages of the Lancet Infectious Diseases Journal. some did work on catching it from a door handle which had been used many times, but another concentrated on the traffic light of a city where thousands would push the button every day.   The Science today that the chances vary from 1 in 10,000 to 5 in 10,000 is well established.    However when the virus broke out in February 2020, there were laboratory tests carried out on surfaces  Several found the virus lived for two or three days, and one carried out by the World Health Organisation quoted a figure of 5 days.   But medical people protested that these tests carried out in laboratories used samples that did not reflect real life, and those that were carried out in real life were soon accepted.

Now for the tricky part.   If what I am saying is true, why is it that in theatres, cinemas, restaurants, and places of worship, there is still such deep cleaning going on?    The first answer is that these facts have in the media remained unnoticed for cleaning and sterilising businesses are making a large fortune out of the labour of the willing staff and volunteers.    But perhaps the chief reason is fear.   "I understand what you are saying but if you do not mind  we will carry on.   It is better safe than sorry."
