South Korea declares health emergency in its 4th-largest city amid concern about new cases. In the past 24 hours, there have been 892 new confirmed cases, with 118 deaths in China alone.
Earlier, China's authorities reported a total of 2,118 fatalities in mainland China, with 74,576 infected.
According to Adhanom, Chinese officials had been including clinically confirmed cases in order to initiate treatment of these patients sooner, because labs with testing capability for COVID-19 in the Wuhan area had been overwhelmed.
Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases, said Friday that the agency may broaden its recommendations for who should be tested if spread in countries outside of China continues to grow. While that was very low compared to 75,000-plus cases in China, Tedros said: "That may not stay the same for long".
China has said the slowing cases are evidence that its drastic containment measures are working - but fresh infections emerged at two Beijing hospitals, and more than 500 others were reported in prisons across the country.

The decision came after Iraqi Airways suspended flights to Iran.
The World Health Organization warned nations could face a serious problem if they fail to "hit hard now" against the virus, which has infected more than 75,000 in China and more than 1,100 overseas.
Health and city officials say the woman who first tested positive had contact with some 1,160 people, both at the church, a restaurant and a hospital where she was treated for injuries from a auto accident.

Tokyo 2020 Olympic organisers on Saturday postponed training for their army of volunteers due to the coronavirus outbreak, but said that there was "no consideration" of cancelling the Games.
On Thursday, the government in China's eastern province of Shandong said that a prison guard at Rencheng jail in Jining, a city of eight million, had shown COVID-19 symptoms in early February and that subsequently more than 2,000 inmates and staff were tested, with 200 prisoners and seven officers coming back positive. Malls, restaurants and streets in the city were largely empty with the mayor calling the outbreak an "unprecedented crisis".
