DALLAS (AP) — Health officials in Texas are monitoring some 50 people who may have had close contact with a health care worker who contracted the Ebola virus from a Liberian man who died last week in a Dallas hospital.
The head of the Centers for Disease Control and Prevention said Sunday that a breach of protocol led to the worker becoming infected while treating Thomas Eric Duncan.
Officials have not been able to pinpoint what went wrong.
The disease is believed to have killed more than 4,000 people in West Africa. Liberia has the highest death toll.
Ebola has hit health care workers especially hard, infecting about 400, nearly half of those in Liberia. Members of the National Health Workers Association are demanding higher monthly hazard pay.
