An eruption of new virus cases in
South Korea,
Iran and Chinese hospitals and prisons rekindled concerns Friday about the spread of a deadly disease that has killed more than 2,200 people.
The World Health Organization warned nations they could face a serious problem if they fail to "hit hard now" against the new coronavirus, which has infected more than 75,000 in
China and over 1,100 abroad.
China pointed to official numbers showing a drop in new cases this week as evidence that its drastic containment measures are working, but fresh cases emerged at two
Beijing hospitals and more than 200 other cases in two prisons.
