The main difference between a unicorn and Sars-Cov-2 is that no one has yet invented a “scientific” test of supposed constituent parts that “proves” the existence of a unicorn, which is a great shame as it would be quite something to observe how many people would be convinced if a ‘unicorn test’ ever returned a ‘positive’. The DHSC also held no information about transmissibility/ contagion but suggested I sent my request to Public Health England. PHE has replied (at last). Here are the relevant lines: Please could you forward any information you have relating to experimental evidence demonstrating that COVID-19 is person-to-person transmissible. PHE can confirm it does not hold information in the way specified by your request. What this means is that no specific investigation has been carried out into the most central assumption (and that’s all it is) that has driven the global “response” to this supposed pandemic!
