After large increases in COVID-19 cases in other countries, the World Heath Organization said the virus had the potential to cause a pandemic but wasn't one yet.

“The past few weeks has demonstrated just how quickly a new virus can spread around the world and cause widespread fear and disruption,” WHO's Director-General Tedros Adhanom Ghebreyesus said.

But “for the moment we’re not witnessing the uncontained global spread of this virus,” he said.
