The World Health Organization has declared a "health emergency of international concern". You do not know what damage the virus will cause, it said.
After the increasing number of diseases caused by the coronavirus outbreak, the World Health Organization (WHO) has declared an international health emergency. This is linked to tighter measures to combat the outbreak.
The number of infections outside of China is still relatively low, said WHO director Tedros Adhanom Ghebreyesus. The "biggest concern" is that the virus will spread to countries with less well-equipped health systems, he warned.
