A second case of the Ebola virus has been diagnosed in the US, officials said, involving a health worker who provided care for disease victim Thomas Eric Duncan.
The unidentified health care worker had been treating Mr Duncan until his death at the Texas Health Presbyterian Hospital on Wednesday, and reported a fever on Friday night.
The worker wore full protective clothing including a gown, gloves, mask and shield while caring for Mr Duncan, according to state health official Dr Daniel Varga.
In a statement, the Texas Department of State Health Services said the worker was referred for testing at a laboratory in Austin, where preliminary tests came back positive late on Saturday night.
The Centers for Disease Control (CDC) in Atlanta will perform further tests to confirm the diagnosis.
“We knew a second case could be a reality, and we’ve been preparing for this possibility,” said Dr David Lakey, the Texas health service commissioner.
