SIR - A recent report from Cardiff University suggests the ingestion of alcohol can damage and perhaps even kill the coronavirus by penetrating its protective layer of fat.

The use of mouthwash containing 20 to 30 per cent alcohol is recommended and a recent report suggested infectivity to other people could be reduced.

While research continues may I suggest that a regular tot of whisky or your favourite tipple nay be beneficial.
