DALLAS (AP) -- The condition of the lone Ebola patient to be diagnosed in the U.S. has worsened and is now deemed critical, the Dallas hospital that has been treating him reported Saturday.<br />
<br />
Texas Health Presbyterian Hospital Dallas, where Thomas Eric Duncan is being treated, didn't provide any further details about his condition, and a hospital spokeswoman, Candace White, didn't immediately respond to emails and phone calls. The hospital previously said Duncan was being kept in isolation and that his condition was serious but stable.<br />
<br />
Duncan traveled from disease-ravaged Liberia to Dallas last month before he began showing symptoms of the disease.<br />
<br />
Health officials said Saturday that they are monitoring about 50 people who may have had contact with Duncan for signs of the deadly disease. Among those are nine people who are believed to be at a higher risk. Thus far none have shown symptoms.<br />
<br />
Included in the group are those people who later rode in the ambulance that took Duncan to the hospital last Sunday, said Dr. Tom Frieden, the director of the Centers for Disease Control and Prevention.
