The World Health Organization is not ready to declare the newly discovered coronavirus a global public health emergency, health officials said Wednesday, even as the death toll reached 17.
More than 500 cases of the respiratory illness have been reported in China, mostly in or near the city of Wuhan. The number is expected to grow by the hour, as cases are detected in other countries, including the U.S.
“To proceed, we need more information. For that reason, I have decided to ask the emergency committee to meet again tomorrow,” WHO Director-General Dr. Tedros Adhanom Ghebreyesus said during a news conference Wednesday.
On Tuesday, the first case of the disease was confirmed in the U.S., a man in his 30s in Washington state, by the Centers for Disease Control and Prevention. The man became ill after visiting Wuhan. He is said to be in good condition, in isolation at a hospital in Everett, Washington.

The WHO’s announcement comes as the city of Wuhan is preparing to quarantine its residents in an effort to control the ongoing outbreak. Beginning Thursday morning, all public transportation out of the Wuhan city limits will close.
That will likely disrupt plans for millions of people in China, who are expected to travel for the Lunar New Year, a major holiday.
The WHO has declared a global public health emergency just a handful of times in the recent past: the H1N1 (swine flu) pandemic in 2009; the 2014 outbreaks of polio in the Middle East and Ebola in West Africa; the 2015-16 Zika virus epidemic; and last year’s Ebola epidemic in Congo.
The declaration is meant, in part, to improve global communication about the new coronavirus, referred to as 2019-nCoV, and an illness that remains poorly understood.
“Part of what is driving the levels of concern that we’re seeing globally is the lack of information,” Lauren Sauer, director of operations for the Johns Hopkins Office of Critical Event Preparedness and Response, said.
“We need more epidemiological data to understand how this is spread, what the clinical illness looks like, how these patients should be identified and isolated,” Sauer told NBC News Wednesday.
She added it’s important for health care workers to have a good understanding of which patients need hospitalization and quarantine, and which do not.
“If we start hospitalizing everyone who potentially has a travel history to Wuhan, we can quickly overwhelm hospital systems globally,” Sauer said.
