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. via My Way News.
