Dallas Ebola Patient Worsens to "Critical"
About 10 people are at "higher risk" of catching Ebola after coming into contact with Duncan.
Thomas Eric Duncan, the first Ebola patient diagnosed in the United States, is now in critical condition, a Texas Health Presbyterian Hospital spokeswoman said Saturday.
The Liberian man had previously been listed as being in serious condition. Hospital spokeswoman Candace White offered no new details other than his condition.
Earlier, the U.S. Centers for Disease Control and Prevention said Duncan was in intensive care.
