A US healthcare worker who provided hospital care for an Ebola patient who later died has tested positive for the virus and is in a stable condition. Dr Daniel Varga, of the Texas Health Resource, said the worker was in full protective gear when they provided care to Thomas Eric Duncan during his second visit to Texas Health Presbyterian Hospital. Dr Varga did not identify the worker and said the family of the worker have "requested total privacy". Dr Varga said the healthcare worker reported a fever on Friday night as part of a self-monitoring regimen required by the Atlanta-based Centre for Disease Control. Mr Duncan died on Wednesday in Dallas. If the preliminary diagnosis is confirmed, it would be the first known case of the disease being contracted or transmitted in the US.
