The head of the World Health Organization warned the coronavirus outbreak has now reached “unchartered territory” with more than 90,000 cases across the globe.

Director-General Tedros Adhanom Ghebreyesus stopped short of classifying the mushrooming number of cases as a pandemic — but acknowledged that the virus’ “unique features” has created an unprecedented health crisis.

“We are in unchartered territory. We have never before seen a respiratory pathogen that is capable of community transmission, but which can also be contained with the right measures,” Tedros said at a Monday press conference in Geneva.

Tedros has previously said that a health situation reaches the pandemic level when there’s “large-scale severe disease or deaths,” as well as “uncontained global spread of the virus.”

However, the WHO chief said that it is possible the virus, officially known as COVID-19, could reach the status of a pandemic.

“We are monitoring the situation every moment of every day, and analyzing the data,” Tedros said. “I have said it before and I’ll say it again: WHO will not hesitate to describe this as a pandemic if that’s what the evidence suggests.”

The virus has reached 73 countries but of the thousands of cases reported globally so far, 90% are in China — and mostly in one province, he said.

To date, it has caused more than 3,000 deaths worldwide — with 172 deaths reported outside mainland China.

The United States has seen 118 cases of the coronavirus, including nine deaths, all of which were in the Seattle region, according to CNN.
