JOHANNESBURG - South Africa's central bank has warned citizens against scammers visiting homes to "recall" banknotes and coins they said were contaminated with the novel coronavirus.

The criminals carried fake identification badges and provided false receipts to victims, who were told they could exchange the slips for "clean" cash at any bank.

The bank said in a statement issued late Monday that it had "neither withdrawn any banknotes or coins nor issued any instruction to hand in banknotes or coins that may be contaminated".

"There currently is no evidence that the COVID-19 virus is transmitted through the use of banknotes and coins," said the statement.
