UPDATE: WHO declares coronavirus a global health emergency

The World Health Organization declared Thursday the new coronavirus an international public health emergency.

This decision comes as cases are beginning to appear in people who have not traveled to China during the outbreak.

The declaration, officially called a “Public Health Emergency of International Concern” helps the international agency mobilize financial and political support to contain the outbreak.

Also Thursday, the first case of a coronavirus person-to-person infection in the United States was confirmed by the Atlanta-based Centers for Disease Control and Prevention.

The latest infection is the Chicago-based husband of a woman in her 60s who recently returned from Wuhan, China, with the virus. Health officials said Thursday the man recently reported virus-like systems and was placed in isolation. Both are reported to be stable.

Illinois health officials said there are now 21 people in the state under investigation for the virus.

Redfield, M.D. “We understand that this may be concerning, but based on what we know now, we still believe the immediate risk to the American public is low.”
