Currently, 76 healthcare workers from Texas Health Presbyterian Dallas are being monitored for possible infection as the hospital treats 26-year-old nurse Nina Pham, who tested positive for Ebola Sunday. She was in good condition as of Tuesday, the hospital announced. Pham had been in the treatment team for U.S. Ebola patient No. 1, Thomas Eric Duncan.
The initial 48 individuals who had contact with Duncan prior to his hospitalization and death have so far shown no signs of the illness, Frieden said. They were past the critical period during which the likelihood of infection would be high.
CDC on Tuesday sent a team of infectious disease experts to Dallas to improve hospital safety. Some of the measures being implemented include having a site manager on hand to oversee the safe donning and removal of personal protective equipment.
Still no explanation has been given as to how exactly Pham got infected. The investigation is ongoing into what happened, but no specific error has yet been identified as the cause, Freiden said.
