Answer:
Step-by-step explanation:
The World Health Organization declared a global health emergency on Thursday as the coronavirus outbreak spread well beyond China, where it emerged last month.
The move reversed the organization’s decision just a week ago to hold off such a declaration. Since then, there have been thousands of new cases in China and clear evidence of human-to-human transmission in several other countries, including the United States.
All of which warranted a reconsideration by the W.H.O.’s emergency committee, officials said.
The declaration “is not a vote of no confidence in China,” said Tedros Adhanom Ghebreyesus, the W.H.O.’s director-general. “On the contrary, the W.H.O. continues to have confidence in China’s capacity to control the outbreak.”
