The World Health Organisation has criticised blanket travel bans made in response to Omicron, claiming it "attacks global solidarity".
With the devastation of Delta still fresh in the minds of many, it's unsurprising countries rushed to enact travel bans after hearing of the highly contagious Omicron variant.
By November 28, just four days after South Africa first reported cases to WHO, some 56 countries had implemented travel measures specifically aimed to delay the import of Omicron. Some countries only restricted travel to and from southern Africa while others closed their borders entirely.
However, WHO has criticized the blanket bans, claiming they place a huge cost on developing countries for very little return.
"Blanket travel bans will not prevent the international spread, and they place a heavy burden on lives and livelihoods," said WHO's regional director for Africa Matshidiso Moeti.
