March 2020: The UK government is taking measures, on controversial scientific advice, to increase ‘herd immunity’. This might have a side-effect or creating millions of potential carriers just when elsewhere the disease is dying down (like in China). Then if the Brits start travelling again it could start a far, far bigger pandemic. Part of this for example would be Chinese students returning to China, some taking active coronavirus with them. Possibly students from China will not be allowed back to China, or similar measures may be taken.
