The World Health Organization declared the coronavirus outbreak an international health emergency during a press conference on Thursday. The coronavirus represents that first respiratory illness to be labeled an international emergency since the H1N1 flu in 2009.

"Our greatest concern is that potential for the virus to spread to countries with weaker health systems, and which are ill-prepared to deal with it," Tedros Adhanom Ghebreyesus, Director-General of the WHO stated. "Let me be clear: This declaration is not a vote of no confidence in China. On the contrary, WHO continues to have confidence in China's capacity to control the outbreak."

In addition, the White House announced Thursday that the country will allow airlines to determine whether or not they will still fly to China. A number of airlines around the globe have announced plans to reduce or halt flights to China, including British Airways, United Airlines (UAL  ), American Airlines (AAL  ), Air Asia, Cathay Pacific (CPCAY  ), Air India, IndiGo, Lufthansa (DLAKY  ) and Finnair.
