DALLAS (AP) — A Texas health care worker tested positive for Ebola even though she wore full protective gear while caring for a hospitalized patient who later died from the virus, health officials said Sunday. If the preliminary diagnosis is confirmed, it would be the first known case of the disease being contracted or transmitted in the U.S.
Dr. Tom Frieden, head of the Centers for Disease Control and Prevention, said the diagnosis shows there was a clear breach of safety protocol and all those who treated Thomas Eric Duncan are now considered potentially exposed.
The worker wore a gown, gloves, mask and shield while she cared for Duncan during his second visit to Texas Health Presbyterian Hospital, said Dr. Daniel Varga of Texas Health Resources, which runs the hospital. Frieden said the worker has not been able to identify a specific breach of protocol that might have led to her being infected.
Duncan, who arrived in the U.S. from Liberia to visit family on Sept. 20, first sought medical care for fever and abdominal pain on Sept. 25. He told a nurse he had traveled from Africa, but he was sent home. He returned Sept. 28 and was placed in isolation because of suspected Ebola. He died Wednesday.
Liberia is one of the three West African countries most affected by the ongoing Ebola epidemic, which has killed more than 4,000 people, according to World Health Organization figures published Friday. The others are Sierra Leone and Guinea.
Texas health officials have been closely monitoring nearly 50 people who had or may have had close contact with Duncan in the days after he started showing symptoms.
The health care worker reported a fever Friday night as part of a self-monitoring regimen required by the CDC, Varga said. He said another person is in isolation, and the hospital has stopped accepting new emergency room patients.
“We knew a second case could be a reality, and we’ve been preparing for this possibility,” said Dr. David Lakey, commissioner of the Texas Department of State Health Services. “We are broadening our team in Dallas and working with extreme diligence to prevent further spread.”
Dallas officials knocked on doors, made automated phone calls and passed out fliers to notify people within a four-block radius of the health care worker’s apartment complex about the situation, though they said there was no reason for neighbors to be concerned.
Dallas police officers stood guard outside the complex Sunday and told people not to go inside. One said an industrial barrel outside contained hazardous waste taken from inside the building. Nearby residents periodically came out of their homes to ask about the commotion.
Kara Lutley, who lives a half-block from the complex, said she never received a call or other emergency notice and first heard about it on the news. She said the infected worker seemed to have taken all necessary precautions.
“I’m not overly concerned that I’ll get Ebola,” she said.
Officials said they also received information that there may be a pet in the health care worker’s apartment, and they have a plan in place to care for the animal. They do not believe the pet has signs of having contracted Ebola.
Frieden on Sunday raised concerns about the possible breach of safety protocol and told CBS’ “Face the Nation” that among the things CDC will investigate is how the workers took off protective gear, because removing it incorrectly can lead to contamination (see video above). Investigators will also look at dialysis and intubation, procedures with the potential for spreading infectious material.
