Bans on international travel cannot stay in place indefinitely, and countries are going to have to do more to reduce the spread of the novel coronavirus within their borders, the World Health Organisation said, according to Reuters.

Only with strict adherence to health measures, from wearing masks to avoiding crowds, would the world manage to beat the Covid-19 pandemic, WHO Director General, Tedros Adhanom Ghebreyesus, said at a virtual news briefing.

“Where these measures are followed, cases go down. Where they are not, cases go up,” he said, praising Canada, China, Germany and South Korea for controlling outbreaks.
