Another nurse noted that Duncan’s urine was "darker in color with noted blood streaks."
It was unclear from the records released to the AP how many of the approximately 70 individuals involved in Duncan’s care had direct contact with his body or fluids.
Dr. Aileen Marty, a World Health Organization doctor who recently returned to Florida International University after a month fighting Ebola in Nigeria, said no amount of protection is going to help if hospital workers do not put on and take off their protective layers carefully.
"The first thing in caring for someone with Ebola is to do everything in your power to never become a victim," she said.
And tracking all contacts, even within the medical setting, is complicated.
Generally, the first step in locating care providers for isolated infected patients is a personnel log on the door, "that should have everyone going in and out, signing in and out," said Dr. Lisa Esolen, Geisinger Health System’s Medical Director of Health Services and Infection Prevention and Control. Medical records indicate the Dallas hospital had a log.
On the day before Duncan died, records indicate that at least nine caregivers entered and exited the room.
A spokesman for Texas Health Resources, the hospital’s parent company, said the CDC probably has a log from the room door that would list everyone who got close to Duncan.
Dr. Christopher Ohl, who heads Wake Forest Baptist Medical Center’s infectious-disease department and has worked with the CDC in the past, said the expanding monitoring "is an abundance of caution that’s probably beyond what needs to be done" because medical caregivers will notice if they’re getting a fever, and they’re not contagious until that point.
"You start to know when you get those body aches and headaches, most people know that," he said. "It’s not like you’re surprised by it. Most people can figure out what to do when that happens."
