The president of Malawi has described travel bans imposed by several nations — including the United States — in response to a new strain of the coronavirus as “Afrophobia,” joining other African leaders in condemning the restrictions.

Many countries have closed their borders to travelers from southern Africa after the new virus variant, dubbed omicron, was identified by South African scientists last week. Experts have warned that travel restrictions probably are too late to be effective, with cases already emerging as far away as Asia and Australia.

The bans have also angered political leaders in Africa who view them as hasty and unjustified — scapegoating countries that have been quick to come forward with information on a potentially dangerous new variant. South Africa’s health minister described the measures Friday as “misdirected” and “draconian.”

“We are all concerned about the new covid variant and owe South Africa’s scientists our thanks for identifying it before anyone else did,” Malawi’s president, Lazarus Chakwera, wrote Sunday in a Facebook post. “But the unilateral travel bans now imposed on [Southern African Development Community] countries by the UK, EU, US, Australia, and others are uncalled for. Covid measures must be based on science, not Afrophobia.”

It is not the first time that countries where new variants have been found have been ostracized for the discovery. The World Health Organization introduced a new naming system, using the Greek alphabet, for coronavirus variants of concern earlier this year in part to avoid the stigma associated with attaching country names to variants.

The highly transmissible delta variant cutting a deadly path across Europe and spreading in the United States was previously known as the “Indian variant,” after where it was first found. Similarly, a strain known as alpha was initially called the “U.K. variant” because it emerged in the United Kingdom.

At critical points early in the pandemic, as the virus first emerged in Wuhan, Chinese authorities appeared to put secrecy and order ahead of openly confronting the growing crisis, potentially delaying its pandemic response.

Dozens of nations imposed travel bans on China in early 2020, sparking a pushback from Beijing, which viewed itself as the original scapegoat. China subsequently proposed an alternative theory that the virus could have come from overseas, possibly via frozen food imports — although it has presented little support for that.

Matshidiso Moeti, the WHO’s Africa director, said Sunday that with the omicron variant surfacing around the world, imposing travel bans that target Africa “attacks global solidarity.”

South African President Cyril Ramaphosa said he was “deeply disappointed” by the travel bans and called for them to be lifted immediately.

“The prohibition of travel is not informed by science. Nor will it be effective in preventing the spread of this variant,” he said in a televised broadcast. “The only thing the prohibition on travel will do is to further damage the economies of the affected countries and undermine their ability to respond to and also to recover from the pandemic.”
