It shows an announcement with the UK government and the National Health Service logos at the top, claiming that under “emergency legislation” the NHS has ordered a ban on the sale, purchase and consumption of alcohol after discovering that it “lowers immunity".

There is no such ban on the sale, purchase or consumption of alcohol in the UK, although the government has told pubs, clubs and restaurants to close.

But off-licences, other licensed shops and supermarkets have been allowed to stay open.

So far, South Africa is the only country to implement a nationwide alcohol ban as part of measures to combat Covid-19.
