All nations should exercise extreme caution while re-opening their borders when the novel coronavirus pandemic begins to subside, said Michael Ryan, the executive director of the World Health Organization (WHO) Health Emergencies Programme, APA reports quoting TASS.
"When we talk about opening up and reducing lockdowns, there’s also the question of how people begin to move internationally," he said.
"Obviously, they need to move between countries, and it’s going to become more and more of an issue and more and more of a challenge. So I think the issue of moving citizens home or just getting people back into international travel is going to have to be approached carefully and is going to have to be done, I would suspect, first at the sub-regional level," the WHO official continued.
"Already countries are looking at how we can re-establish the movement. Some of that would be based, I think, on risk equalization and response equalization: where countries have a similar control of the disease, where countries have confidence in the measures being implemented in the other country, then, in fact, the risks are equalized and the movement of people between those areas, in a sense, does not add risk to the other country," he went on.
