GENEVA (Reuters) - The head of the World Health Organization (WHO) voiced concern on Tuesday that some countries were introducing blanket measures against the Omicron coronavirus variant that may not be necessary and penalised African nations unfairly.

"I well understand the concern of all countries to protect their citizens against a variant that we don't yet fully understand," said Tedros Adhanom Ghebreyesus.
